Chronos User Discussion / Re: Let's talk LENSES!
« on: October 14, 2018, 02:02:09 AM »
Oh, Wow, Thanks for the info. I never knew how those Auto-Iris Lenses Worked. I also never actually owned one myself. But good to know anyways.
.
I wont buy that lens, since it is for 2/3", which is perfect for the Chronos, but wont cover the 1" sensor of my Nikon1 completely without vignetting (Just guessing). Just stumbled across this thing on Ebay and found, that it would be worth posting here since the Lens is most likely good brand Quality and quite Cheap, very wide and a good Fit for the Chronos. Also, most people would have the 12-75mm Lens, so an 5,6mm like this would be an Nice addition to anyones Camera, both for wide-Angle/ Tight spaces and also for lower Resolution/ very high-framerate Shooting.
.
If someone buys this, and happens to own some Kind of mirrorless Camera, it would be very nice if he could take an image with this lens, if the image Circle of the Lens is 15mm or bigger, i will also get one of those. Otherwise its not worth it for the use on the Nikon1 for me.

Here is an very wide Lens for an reasonable Price for anyone searching for one.
CS-Mount, so no Distance Ring required.
Lens is auto-Iris so you propably cant change aperture on the go and most likely will need to use it wide open all the time.

  • This might not actually be a camera/sw bug, but the produced DNGs can't be opened by my Photoshop (CS5 with CameraRaw 6.7.1). As far as I can tell it basically complains (understandably) that it is has now idea about the used Camera Model I was however able to open the DNGs with UFRaw, so maybe there are just a few settings missing in the files or Photoshop can't actually display DNGS from "unknown" cameras at all.

.
The DNGs directly from the camera also wont open with none of my Software: Photoshop CS2, Photoshop CS6 Extended or AfterEffects CS6.
But someone uploaded DNGs here in the Forum, which presumeably where generated by that pyton-Tool, those open just fine with my software (not tested on PS CS2...).
So there should be some way to get DNGs directly out of camera which would be able to be opened with common Software i guess. Would most likely just be some small problem there, but i honestly have no idea how exactly those Files/ Container-Formats/ Tags on the Files work.

What is that overlay on the Clip?
Is that done in post or can you add it in Camera already?
It can be done on the Chronos directly using the last beta software.
Ok, well, thats Cool!

My 1.5 inch bore black powder cannon at 10000 fps shooting a tote of water.

Projectile, 1.5000" ball bearing.
60 grams FFFg powder.

Also, if done in post what software was used for that?
I had to do an similar overlay for an Analysis of the exact timing of a Machine, that kept Failing.
But since the only option i had was to shoot at 1200fps, it was quite a pain to add exact timing-Overlays on the Frames. I did mine in Adobe AfterEffects 6.0 back then and manualy animated the Numbers to give correct timing information on each frame.

This looks quite promising. What is shown on the last pic? I can't figure it out...
Maybe this last image should just show off production Quality i guess. Details you normaly wont find on an Selling Website. To get an better idea what you get when you buy that exact same monitor.
Yeah but WHAT is ist? does not look like any part of the monitor to me
There you can see which part of the Monitor it is:

So after reading this thread I know that I want to get a speed booster/focal reducer for my Cronos. I'm just not sure what lenses will be most affordable to get for this idea. I have a Markforged 3D printer and a very nice machine shop that I have unfettered access to that I can make all kinds of widgets. So I have the resources to make it happen, but not the knowledge to execute on it. The Cronos is my first ever not a cell phone camera and I am still learning a lot about lenses in general and I'm getting a handle on it I think, but I have no background on different mount systems and cameras and the lenses for them. If someone can help me figure out some solutions I'd be more than happy to make extra parts of anything I have to manufacture to make it happen.

I could start with Nikon1's 3D printed widget. I could either use a MFT lens straight on that or a MFT to ??? speed booster with a ??? lens mounted to said speed booster correct?
You could use any native MFT-Mount Lens aswell as an MFT-To-Somethinge_Else-Speedbooster.
Just make Sure to get the Flange Distance right.
My 3D-Model posted here is just guessing on the Data i found around here.
Cant verify that it works (Since i still struggle to get enough money together to finaly buy an chronos myself...), so you maybe need to adjust the Height a bit to get proper Focus on infinity and close Objects.
For MFT-Mount Lenses make sure, that you have any way to adjust things Like Focus and apperture on the Lens itself, since a lot of MFT-Lenses are Focus-By-Wire only, so that will mean, you need an Camera with an electronic connection to the Lens to make any adjustments to the Lens. And you (obviously...) dont get any kind of Electric Connection with this 3D-Printed Adapter and the Chronos.
.
For myself i have to say, i would only get an speedbooster if i actually had an existing collection of really good, already fast Glass for an bigger Format or an seperate Camera System with an way bigger Sensor.
Otherwise, if you have not allready a lot of other Lenses or an seperate other Camera system laying around, also look into "native" lenses for the Chronos, like C-Mount and CS-Mount.
There Are Lots of very great choices in every single Mount available, most very good options come at an price though.
Nice thing about the Chronos is, that you can basicaly just can adapt virtualy everything to it, even Like Sony-E-Mount or even Nikon1-Mount-Lenses. But Try to avoid Focus-By-Wire, like said earlier allready. Will make your life a whole lot easier.
If you need help in designing an adapter for some other special mount, just ask, i will take a look at it if i can do any helpfull about it.

Chronos User Discussion / Re: Cheap SD cards class 10
« on: October 02, 2018, 02:15:02 AM »
Guys, you spent several thousands on a camera, and want to save big on the SD cards? Really?
There Will allways be those kinds of people who buy the most expensive Cameras and expect it to make somehow Magicaly good pictures or videos on its own and then they try to be cheap on Lenses, Tripods, cards, Lights and so on...
And i think this is not only exclusive to DSLRs or the new Mirrorless-Craze (just to be clear, i like DSLMs...), this also applies to Chronos-Users.
Something about Cheap Lenses on Expensive Cameras:

Be very careful with (micro) SD cards, there are chinese clones everywhere and they just copy the specs on the website but the card will never meet them...

Personally I only buy good known model/brand from reputed sources and I never had any problems.
Like i said i would be pretty surprised if this card with such an high capacity performs well at such an low price point.
I Bought an cheap 512GB Micro-SD once without any Specs about read/ Write Speeds and it was super Slow.
Since it was for someone Else (and had to be cheap and big), who would only put Music and Audio files on there (And propably almost never change them), and would just replay them, it was completely fine for that.
But if you plan for using this in any kind of camera, i personaly would buy some Reputable Brand.
You dont want the Card to fail, which could easily happen with this china-Stuff, especialy if you put some Work into whatever you film...
My Micro-SD-cards cost between 50 to 100 each and are "only" 32 or 64GBs each. if you want an super-high-Capacity one with good R/W-Speeds and that would be durable, you will pay a lot...
Would highly recommend to not be cheap on cards on which you have to actually rely on.

So, what happened to Pritchboxer?
Are you still here?
Would still love to see what you can do to those DNGs :)

Those super-High-Capacity Micro-SDs are usualy pretty slow, especialy at that price point.
If the card would be fast, you Would find ratings somwhere on this website, but since i didnt fnd any info about card Speed there, you could expect it to be an rather slow Card.
i dont know, How that would affect Save-Times on the chronos, but for general Usage i can not recommend slow and Big cards like this, unless you plan to use it as an storage for an media-Player to write once (Will take some time to fill the card i guess) and Play multiple times.
Read Speed usualy are not super bad, but Write Speeds are Painfully slow most times with cards like this.
