Title: Chronos 1.4 Footage Thread
Post by: PaulBryanTV on June 15, 2017, 02:30:01 PM
Hi guys and girls!

I thought it would be a good idea to have a main thread for people to post their footage in.
So whether it's a piece filmed for a YouTube video, or just some test footage, post a link below and let's marvel at the Chronos footage.

Also as jefish said below, please put 'Chronos 1.4' in your title and tags on YouTube. It will help for those who are search for footage!

Peoples Channels (Forum name if available):

Please DM me if I haven't added you yet, I'll update as I go along and see them!

Also, please put 'chronos 1.4' or at least 'chronos' in your Youtube descriptions, if you happen to think about it.

I know there must be more videos out there by now, but they're not showing up in search results.

Exact same thing I've been doing every day, not much new even though there are units out now.
I'll add that to the original post :)

Anyone else get this line? Mainly in areas of lower exposure and I think on resolutions under 720p.

Did you do a black cal?
Title: Re: Chronos 1.4 Footage Thread
Post by: Critters on June 16, 2017, 02:19:17 PM
You need to do a black cal each time you change the resolution, and it helps (i've found) to do it after the camera has warmed up a little

I did a black cal yeah, it seems to be directly on sensor, as when I move the recording 'Area', around the line moves accordingly, as well as some other spots similar to it.

At 720p the picture seems fine, but at lower resolutions the lines appear as seen here - https://www.youtube.com/watch?v=SIRFr4rGwM0
They do not display on lighter pixels, but do in shadow / midtones.
I did a black cal multiple times, restarted etc, still there.
Is it a sensor problem, user error or software?

The Line that shows up at lower resolutions is a current software issue and is high on the debug list. I will update this message when I have more info on the issue.

I am guessing it seems to move up and down when you change the shutter timing as well?

I haven't seen any steady lines like those shown above but occasionally I have seen light/dark bands that will move vertically as the exposure time is adjusted. I'm not sure if they are associated with any particular resolution or frame rate but I'll see if I can reproduce it.

How about some electrical arcs crawling across and through wood:

Anyway here is a video of what's going on guys - https://www.youtube.com/watch?v=n7jFQWE8b28&feature=youtu.be

In the first part I just lower the aperture to make the lines more visible, there is one permanent dark line, one lighter line, and then the bugged shutter line.
After the text, I am simply moving the shutter to show the moving line bug.
Help? It sort of makes lower resolutions unusable currently.

The line is there for most shots over 15Kfps, It is most noticeable in low light situations. As long as you have plenty of light it shouldn't be an issue. We do hope to have the bug fixed in the next software release.

I had one sensor that had a problem like this, but it was quite obvious, I sent that sensor back to Luxima for evaluation and am waiting to hear back. This camera may have a similar problem but not as bad. I'd like to swap your camera out for another one and investigate the issue, especially to figure out a way catch these problems in production.

There are 2 permanent lines, mostly noticeable in lower light, one dark line and one lighter, both about a 3rd from bottom / top.

Funny how both the dark "Spotting" non-linear pixels and the black lines both show up in under exposure. Could it be that it is the same problem that a 3 point calibration could solve?

I have seen the lines myself at high shutter speeds and could be some AD problem from the readout timing.

Title: Hitting nails, very high frame rates!
Post by: gyppor on June 19, 2017, 10:02:35 PM
Being able to go well above 1000-1200fps (where my two other cameras maxed out) seems to open up entire new worlds, there are so many things to film right at home. I love it, hours and hours of fun. I still feel like a kid on Christmas eve.

Hitting rusty nails with a hammer, filmed at 13,000-38,500 fps. Lighting was not optimal, there was cloud cover so I had to use a bit of gain to make things look ok. The shots turned out decent despite the exposure being just 26 microseconds in the last shot.

Taken with the computar lens from about 1m away.

All three of these shots were with a 135mm f2.8 from the 70's. The softness in the first two is from having the aperture wide open and having a lot of glare from behind and beside the subject. The last clip shows off how sharp the Chronos 1.4 can be with the right lenses and lighting. Thanks David!

I agree, I love that shot! I've got a few lenses coming soon that will give me some more range of motion for stuff to record in interesting ways!
Want to work with ballistics and explosives a bit more now that we can comfortably achieve frame rates that show the characteristics of them in slow motion.

I'm using a vacuum cannon but for anything larger than a ping pong ball it won't work (has to do with the mass of the air in the barrel vs. the mass of the ball). Before you build anything check your local laws as going over certain speeds or Ek can get you in big trouble.

I'm not a big fan of firearms, however things that can launch corks, ping-pong balls and larger past the speed of sound is simply brilliant.

DerpykV, your going to have to take some more shots with it and an (realtime) overview video.

nik282000, love how you can see the pressure wave build up and the disk break just before the ball touches it.
I'm assuming you've tried it with clear packing tape too? I've used it very well in the past. That with enough lighting, the ball painted black/white and the camera aimed as strait down the barrel as you dare would give give a very interesting shot indeed.

400 psi? Holy crap! What kind of speeds were you getting?

Electra, on my early versions of the cannon, air that slipped past the ball would build up and pop the mylar like you mentioned but in the gif I posted I am using a modification that eliminates the back pressure and allows the ball to hit and break the mylar directly. I do have some transparent mylar in the shop but I haven't tired it yet as it is heavier than what I am currently using and I'm not sure if it will negatively impact the ball speed. Lots more to think about and test on my end.

Anyone think it could be a cool idea to do a Chronos 1.4 Footage Compilation on one of the larger YouTubers channels?
I think Tao did something like this a long time ago?
Be a great way to get some of the cool footage we all film into public eyes.
Of course it would only be with the generosity of one of these remarkable larger channels. But I think it would make for some good viewing!

To be honest at this current moment Krontech currently does not have the production capacity to deal with a higher order rate than we currently do. Once we have the Kickstarter orders completed and we can expand into a larger office/production facility it should be good.

I'm assuming the popcorn is in a pan? And it's not just being cooked by the lights?

I wasn't working the Chronos 1.4 camera. I was working the remote start for the camera in the video that is closer to shot lol. I know about the Mark in, Mark out and Save but I don't think he did that. He saved it to the memory card rather than uploading it straight to the computer. Also, I'm not the best at editing videos lol. I just started becoming familiar with cameras when in June. We needed to find a high speed camera and we came across this one and saw all the positive feedback so we decided to get this one. I am so glad we did, this camera is great!  :D

Getting to shoot the Hurley Pro in San Clemente
loving the camera
the screen is super dim for focusing in bright light, focus peaking is decent but need the HDMI out in next firmware to hook up an eyepiece for outdoor action shooting
having to find shade and hide under a towel to see what I'm doing
the camera has locked up on me probably 4-5 times in shooting all day every day this week, needing a restart
it would be great to have a kelvin temp selector for setting white balance if you don't have a white card
would also be good to be able to save settings for things like focus peaking color and intensity
just read the forum on how to change frame rates going to try that tomorrow

Camera arrived yesterday.  I took a trip to Microcenter and got a 256 gig SD.  Didn't have much time (or interesting subjects) to film.  Turned the camera toward some bubbling fry oil in the kitchen and this is what I got: https://youtu.be/qeZXKtkyRRc Was kind of surprised by just how shallow the field depth was at f/0.95. I could only cleanly focus on about 1/3 of the pot from about 3 feet away.

Here is a test video lighting of a e-match
https://vimeo.com/236510378 (https://vimeo.com/236510378)

The footage was shot at 800 x 600 at 2,873 frames per second with a shutter speed of 89 usec or about 1/11,000 sec.  The e-match had a resistance of 1.227 ohms measured with a milliohm-meter.  The red LED is in parallel with the e-match so the current starts flowing in the e-match when the LED lights.  There is immediate reaction but the pyrogen doesn't start burning for about 0.1 second later.

The objects were illuminated with home built LED lights using a constant current source.

Something like that might work, I was thinking of making something that looks like a rifle stock that lets me support, aim and trigger the camera with one hand and use the other for focusing only. Having a handle on the focus ring would definitely make it easier to hit the same mark repeatedly, thanks!

As we are a firearms marketing firm ,expect more of that soon!

Got some new footage:

https://www.youtube.com/watch?v=SPf6Pv2KeGk

It was on a German "outdoor" shooting range, so basically indoors... low light conditions. Still don't have constant light sources to illuminate the scene.

There are colored lines visible some times. I know this can happen when the memory is cold, but it was about 16 °C, which I wouldn't consider cold. Is there any way to prevent this? I plan to do some more filming in early January, and don't want all of the footage to show these lines.

Also I got trouble with focusing. It seems like the adaptor ring doesn't have a good hard stop, and the backfocus needs to be set depending on the torque that was applied when mounting the lens. I still store the camera in its shipping box, because this is very well stuffed, but that means I need to take off the lens for storing.

Any ideas on how to get this fixed?

The cold temperature RAM issue will be completely fixed in the next update. We're just testing this update right now before releasing it, expect it in a week or so assuming no problems are found. We've tested the camera down to -20C and there is no issue at all with the new software.

To avoid taking off the lens, cut out a portion of the box foam so you can store the camera without taking off the lens. Also, check that you tighten the backfocus lock setscrew enough, if it's not tight the ring will spin and change backfocus when you screw the lens in hard.

Here's a quick one, a great shot (scientifically speaking - resolution is low) showing a shock wave produced by an explosive target.

As a bonus, the shadow of the shock wave is also visible. As the shock wave moves through the air and compresses that region, the refractive index of the air changes, making it act like a lens. This is what causes this shadow to be visible.
Or something like that.

I often find the joy of filming in high speed is finding out that you've inadvertently captured something after the fact. There's so much to look at in even a short clip. I love it.

Hey :)

Did you film using the battery or was the Chronos plugged into a power outlet there?
If it's been on an outlet: maybe there are things on the same grid which introduce small linespikes and result in such artifacts?

All the best

Yep it was v2512 with fast option and larges memory. Only problem was the finnish weather and short day :D But I got funding for the camera with really short notice and it's just couple days in country when you order that so you get the weather that happens to be on filming day. We actually filmed this week also one day with the thing since one of my friends customer needed 80 000 fps camera so they had to rent that one again and they needed it only for one day and I got the second day really cheap since minium rent period is two days.

This time we did some DIY shaped charges and 70 litre gasoline bomb :D The shaped charges looked quite nice with the phantom but I got also really nice clip with the chronos from gasoline bomb. I am publishing that video tommorow and I can add link here when it's out.

But in generally I think that the v2512 phantom and chronos are good match for youtube videos. You can take clip from small details with really high frame rate with the phantom and then wider shot with chronos with speed aronud 1000-3000fps. I am probably filming next time when it's bit more light or if I get somebody else to pay for the phantom.

I think this is also really nice shot https://youtu.be/HcTRapGoHK8?t=3m43s
It's the same reaction filmed with two chronos cameras, color version and black and white. I had color version recording 500fps to get more light and black and white little bit faster. I think I could do better now since this was my first video with the black and white model and I didn't know how to exactly set it up to get best possible picture.

Howdy, thanks!  Yeah, I communicate with him all the time.  He'll be at our booth at the SHOT show, 20645 in the Law Enforcement section.  He got screwed the way a lot of us with gun channels did, with most of our videos that have been up and monetized for years all of a sudden not being "appropriate for all advertisers".  Fortunately I have a good day job; he didn't.

Lets be honest, there is lots of old stuff that is cool to look at, but you are happy you don't have to actually use.

I have been going to the steam thresher reunion in Rollag, MN ever since I was a child. Lots of fantastic machines. Glad we don't have to run our society off them anymore.

Crash testing lego cars. Had some settings wrong and we need a longer runup but it shows promise. (And editing mistakes at the end)

https://www.youtube.com/watch?v=4yQ6KYem8z8

The car is pulled along by a kilo wight and spectra fishing line over nearly a meter. Surprisingly realistic results.
Next time we've got a space that will allow 2.8m of runup. So we can go from scale speeds to insane speeds. :)

Electra, what an awesome idea! :D
And the "let's be fair" comment and continue smashing the first one in "4-year-old" mode, was funny, as was the whole video :) Thank you!

Maybe just "half press" each Lego brick? Tight enough to hold and not losing too many bits on the way, but loose enough to have the tendency to deconstruct fantastically..?
I'd recommend heavier pull weights, exact offset impact, maybe with a guiding rail solution and maybe inserting weighted inlets (lead) into the car, to increase mass (maybe only with heavier pull weights)?

Love to see more! :D

All the best
Martin

Hello, at first sorry for my English :D  here some of my first shots with chronos.

Airsoft grenade - i messed up a little bit montage (doing it for first time :D ) so quality of footage is not the best, in second link i put some "clean" file of first explosion, it's look way better (and its still after yt compression, on PC look even better). First explosion is 1000 fps, and second about 5000 fps - second one looks really bad because i had to much sunlight on screen so i didn't even see the settings :D 

https://www.youtube.com/watch?v=-ykGt13FaQ4
https://www.youtube.com/watch?v=OKJIW2ke1Vw

And today I was taking some shots of water drops but I fast realize that computar lens isn't the best for that.

https://www.youtube.com/watch?v=g8-rTKL6CoU

Still learning the camera but it's pure pleasure to do it, in future i will post more for sure.

Bonus - setup for light to filming water drops :D

Filmed @1000 fps at the German Championship in Cowboy Action Shooting Black Powder.

First two videos show me with my 1873 short rifle, the second two videos are with one of my Shofield Revolvers. 3 shots each.

EDIT:
The clips were shot at low ligthing. It was about 1600h in the afternoon, on a German "outdoor" shooting range. Layout of range see here: (no slowmo in this vid) https://youtu.be/qLkEXiOPwjM

The flickering in the background is 50 Hz from the electric lighting on the range. I had to crank up brightness in YouTube to make the action visible at all. I'm trying to brighten it up in a better video editor and re-upload it. The quality of these edits is just poor. Sorry for that.

Finally got to a range with all the new lighting I've accumulated since getting the Chronos and here are some initial test results.
There's a horizontal band which I couldn't get rid of on the day, but hopefully we'll find out the reason for it before the next tests.

All of this footage was shot using a Nikon 10-24mm f3.5 DX and Nikon 35mm 1.8 DX prime attached to a Metabones XL Speedbooster using a MFL to C mount adapter made by Aimed Research. Still could have done with more light as it was a dull day and the range was mainly in shadow, so I didn't get much help from the sun!
Shows promise though I think.

The reflex sight is an Amazon special, not the cheapest one but it's not made for a real gun. To mount it I drilled a 1/4" hole in "gun rail" which is used for mounting hardware on to guns, and ground down a 1/4-20 screw to sit as flush as possible with the top of the rail. If the head sticks up too far the sight won't mount properly. There are kits that let you mount gun rail to a hot shoe (camera flash mount) and kits that let you mount a hot shoe to a 1/4-20 hole but the taller your mounting setup the more parallax error you will get and the less stable it will all be.

Every time I shoot the sight has to be adjusted, it moves a little while being transported but mostly it's to account for the range of distances I am shooting that day. By picking a spot midway through the field and centering on that it is pretty accurate as long as I remember to aim high for close subjects and low for distant ones. If you are going to film fast moving subjects it is worth the $30.

Yeah, its a 400mm f6.3 non-telephoto lens. Being f6.3 makes it only good for very bright sunlight but it is not heavy compared to telephoto lenses so I always keep it in my kit.

Ok, for that kind of Focal Length on that small Sensor, you would propably want a gun sight.
Would be kind of difficult without i guess.

Couple of videos as we really start doing doing some cinematic and industrial work with the 1.4

Ar500 target testing and glass armor testing. The target testing saved the company more than a few dollars when they saw bullet spall being cast out to the front due to some basic plate misalignment, it was corrected before production saving thousands of dollars in recalls.

Post by: Buddlich on May 29, 2018, 12:11:22 AM
Hi Nikon1,

I used the Fujian Prime lens from the store and a Back-Bone Computar 1/2″ 8-48mm F1.2 6X Zoom C-Mount Lens. It produces that vignetting if it is fully zoomed.
Hadn't enough space between action and camera so that i couldn't zoom in to see no vignetting...

Until now I have not found a solution to get rid of that problem :(

:EDIT: BTW: Nice Colors on those HIghspeed-Shots. TBH the first clip filmed on a chronos (which i have seen at least) where i realy like the colors and find them realistic. Did you do any fancy Editing Magic on that or is it just straight out of camera? :EDIT:
Hi Nikon1,

I used the Fujian Prime lens from the store and a Back-Bone Computar 1/2″ 8-48mm F1.2 6X Zoom C-Mount Lens. It produces that vignetting if it is zoomed out.
Hadn't enough space between action and camera so that i couldn't zoom in to see no vignetting...

Until now I have not found a solution to get rid of that problem :(
Ok, now that makes sense. I was wondering, if the 12,5-75mm Standard-Lens would vignett so badly on the Chronos...
But if that is just a 1/2" Lens, than this makes much more sense.
The only thing i know of, that would be realy wide and also "affordable" @230€ is this lens:
https://www.amazon.com/Azure-Photonics-AZURE-0614MLM-C-Mount-Megapixel/dp/B00OBMUSUK/ref=cm_cr_arp_d_product_top?ie=UTF8
Amazon and B&H are the only places i have found it yet for sale.
But i dont know if B&H ships their stuff to Germany.
Have never seen one sold used.
Should cover 1" completely while not beeing Fisheye.
I donīt have this Lens Yet, but that will be one of the next Lenses to get for my Nikon1 J5.
Or maybe try a Wide-Angle-Converter (Like 0,8x or 0,6x) and combine it with the 12,5-75.

I did just remember that i had a 0,5x Wide-Angle-Converter lying around. i just tried it, and it would work great with the 12,5-75mm and the Chronos.
Pictuers attached to that post. Also pictures of the Converter itself.
(http://)
Shot on the Nikon J5. The Red Frame Shows the Chronos-Sensor-Size.
Both Shot @ 12.5mm. The one With Converter is unfortunately out of focus by a little bit.
I dont think, that this will give you a real 6mm Focal length, but it makes the Lens quite a bit wider, while almost not vignetting.
For 16:9 it should be no problem at all.
.
Since i dont use it and since it would also most likely be not worth the effort to trying to sell that thing, i can offer to send it to you for free if you like it.

Here are two videos I took off of my set up filming rockets at the Spaceport Americas Cup.  This one pitches and follows the rocket and shoots at the default 1,057 fps.

This fixed mount is located near the top of the rail and shoots around 2,000 fps.  I hope to post how this camera was protected in the near future.

I'm impressed with the performance of the CHronos cameras.  They ran about 10 hours in 107F/40C temperatures and had no difficulty with them at all.

Your footage is amazing! Did you follow the first rocket manually or do you have a jig with some kind of actuator that pans the camera?


Here are two videos I took off of my set up filming rockets at the Spaceport Americas Cup.  This one pitches and follows the rocket and shoots at the default 1,057 fps.

Thanks, the cameras pitch automatically based on the rockets acceleration and liftoff is detected with a switch on the rail.

The mechanism is straightforward, a geared motor controlled by a Pololu Jrk21v3 motor controller with feedback (https://www.pololu.com/product/1392 (https://www.pololu.com/product/1392)).  The feedback is provided by a potentiometer to provide position.  It is triggered via a switch at liftoff and uses a slight delay.  The other cameras in this particular set up are the Sony a6300 for stills and a Sony X1000.

What Lens do you have on the Chronos in that Picture?
Looks fairly wide to me, like around 8mm or 6mm or so?
Maybe Kowa?

Finaly sombody did a (more or less) proper Comparison between the Chronos und and an Sony RX, which has the same Sensor as those Nikon1-Kameras (and Therefore basicaly the same Image Quality).
Also in the Comparison a Phantom from Vision Research.
Chronos seems to have the smallest Dynamic Range in that Comparison.
Still Waiting for that HDR Mode on the Chronos. Chronos could have way better Dynamic range with the HDR mode Than any of those other two cameras, realy looking forward to that.

That Video is not my own work btw. It is from BTP/HPC on YT.

Yes the lens in that image is the Kowa LM8XC.  I use a 5mm Kowa for the camera on top of the rail.

Havenīt got my Hands on that exact Lens yet, but i own an Kowa 8mm 1.4 for 1" and it is realy amazing. Got it used in almost new condition on ebay for someting like 130€.
Would expect that 8,5mm to be amazing as well.

A buddy and I have been doing videos on youtube for a couple years, and finally had the experience and confidence using the chronos to go for our one take at blowing up a rifle on high speed.

Any Idea, why there are Artifacts in this Video (referring to the Cronos Footage at 6:45):
https://www.youtube.com/watch?v=EBypmvktKJQ
I have seen artifacts like this in quite some of his videos. Always wondering about that.
I guess he uses the Chronos realy much and maybe put it through quite some abuse, given the stuff heīs Filming, all the Explosions, and so on, and the extreme temperatures in Finnland.
Could that be the Reason for those Artifacts or is this because of bad SD-Cards (which are used too too much, for Example).
Or what else is that?

Nice Footage, have just been able to watch in 480p, because of slow internet and not so much time... but looks realy sharp at 480p.
Is that first real-time part of the Video also filmed with the Chronos? It has MUCH more Vibrant Colors and also more Contrast than the highspeed-Footage. Or is it just different Grading.
Havenīt seen the video in full resolution, but if the first part of the video would be actualy 4k resolution, then it was maybe shot on an GH4 or GH5 or alike anyways...?

No no no, The real time part was filmed with a Panasonic HC-X1000 4K Cam. :) (also see the video discripton for all my (video)camaras)
I wish there will be a 4K Chronos-Version in the future ... or at least a FullHD Version * _______ * Oh my... Alone the idea lets me save money on it. :D

I am waiting for a affordable 1080p Highspeed-Camera with reasonable image-quality for a realy long time.
But i realy hope, there would come something up sometime soon.
The GH5, the Nikon1-Line and The Chronos are a big step in the right Direction, but we still have quite some way to go...

It is really freakingly hard to film flying birds...
however I managed to get one half-decent shot:
https://youtu.be/o6WquZ96vUo

I cant wait for external monitor and zooming in software, it should make focusing much easier.
Also: I'ts great that you can do such shots without any prep at all. I just went outside and pointed the cam at the next best flying thing. Those birds are fast! I had no time to setup focus and aperture.

If you want to film birds I _really_ suggest getting a gun sight and mounting it on top of your Chronos. Before shooting you have to align it with some object at the same distance as you expect to be filming and then you are set. I have used it to get frame-filling video of birds in flight, taking off and landing. (https://imgur.com/FxxIw9q)

You could also try spliting or cuting something like a Playing Card mid Flight. If that is too hard to pull of alone, you could maybe mount the Card somewhere.
Another idea (sadly not involving Swords) is to put screws on a Speaker and Turn up some Music, then upload the Slowmo on YT and call the Video someting like "Screws gonin Nuts".
I dont know why nobody has done that yet.

I was really surprised how well this weeks Chronos footage compares to our previous Smashinator videos that were filmed with +200 000€ Phantom setup. https://youtu.be/MYoBkIzkH1k

Sure it's bit nicer and with high frame rate but on Youtube use especially framerates bellow 3000fps are pretty damn nice.

Nice to see you around here!
I always wondered, do you use the Chronos "Kit"-Lens for all your shots or did you ever try using any other Lenses?
I dont have that same Model of the Kit lens but an much older, similar Lens and i find it not to give good image Quality, even stoped down.
Maybe this newer Version of the Lens is much better, but i would guess that there are still a lot of lenses with better image Quality than this kit Lens.
So it would be interresting if you ever looked into the whole thing about Lenses, because sometimes Lenses could make quite a difference in image Quality.
From your red hot [things] Videos i would assume, that you have a TON of Light when you are Filming those.

I think I should try out prime lenses that I have now here for the cameras if there is a difference. But in general we need zoom lenses on all cameras when we film since we don't have much time to use per one video, safety things also dictate camera placement and with high speed cameras the changing resolution makes things also bit hard. I try to always stay over 2 aperture since I think under that picture comes out always bit soft.

The point i tried to make is not about Zoom lenses vs Prime Lenses. Its not like it would be a crime to use a Zoom Lens or something  :)
If you need to use A Zoom that is fine.
What i Wanted to say is that there are a lot Better Options even for Zoom Lenses, and i was just curios if you ever tryed someting else than the "Kit Lens".
The 12,5-75mm kit lens is a pretty reasonable Preformer for the Price an Size of the Lens but is still a fairly low-End Lens qualitywise.
.
If you must have Zoom then maybe check out Lenses Like the Sigma 18-35mm f/1.8 or the 50-100mm f/1.8. Also, maybe a 24-70mm f/2.8 and 70-200mm f/2.8. Those are realy good Lenses, there are a lot of different ones on the Market and you could get some older model (without Autofocus) for quite good price.
Keep in mind that you could pair all of those Lenses mentioned above with a speedbooster like a Nikon-F to MFT one. Those Lenses should give you an Optical performance very close to an Prime Lens.
.
If you want to go with only one lens, then have a look into ENG Lenses , for example B4-Mount Those tend to have MASSIVE Zoom Range, sometimes up to 20x or even more, Aperture up to f/1.6 for the full Zoom Range and Built in Macro and can be found for high resolution Cameras. Sensor Size of the Chronos is perfect for those Lenses.
.
If you could afford changing lenses more often, Prime Lenses are also a serious option, because you could get smaller and sometimes cheaper lenses which still perform very well.
.
But most good stuff costs good Money...
If you just want to test out Lenses, then here a quick tip:
Visit a camera Store, pretend you want to buy something but want to test it bevore.
If you REALY like it, you could buy it, but you could always say you have to think about it and just leave without buying anything.
But get yourself a adapter for the Lenses you want to test BEVORE you go to test them, because the usualy dont have such adapters in the Stores!
