Attached to this post is an JPG Image containing the Text "TEST".

It looks like we overlooked a configuration variable during the forum migration, but it has since been fixed. Sorry about that!
Means Images working again now?

Not sure how fast the auto focus would be on a Chronos !

did you Format the SD Card in Camera?
 Have you tried if it works with a Different SD Card?

Chronos User Discussion / Re: Chronos powering-up problem
« on: July 31, 2023, 02:38:51 AM »
Hi,

We are facing a strange problem with our chronos 1.4 camera. If there is an AC power and if we unplug it, the camera can be turned on and off without problems. But if we remove the battery to swap it, the camera can not be turned on again (the power button does not react - absolutely nothing happens) until we connect it to the AC power (it is sufficient to plug it for only few seconds, then the camera can be started from the battery).

Could You advise what is wrong?

Thanks.
There is a Setting somewhere on the Camera to lock all Inputs for Shipping, called Shipping mode. it will disable the Camera to be powered even with a loaded Battery installed, and can only be Powered on, once the AC adapter is plugged in, to confirm it has Arrived at the Customer. Sounds like that Mode is possibly enabled, check your Settings for that. (though its weird, if it does that every time; its supposed to only do that once)

oh, i just re-read your earlier Post, and you Said other Lenses mount fine to the Adapter. That Pretty much confirmes then, that the little Spacers on the Backside of the Front Ring are Probably a little oversized to fit the Metabones.
 .
 Only Question now is, if you have any way to somewhat accurately Meassure those Tabs?

I am trying not to insult People by asking super dumb and Basic Questions, but sadly more often than not i seen the Problem actually being the most Obvious and Basic Errors, so i kind of have to ask at some point. However, thanks a lot for Clarificaton, so i can assume you know the basics on how to handle and Mount Optics and such.
 .
 As for QC, i had my hands on Adapters from this type from three different Batches, and Krontech had quite some QC issues on the First run, was really not happy with that one and sent it back myself. the Next batch was better, but still had some Flaws, however i did Keep that one, and just fixed the Problems myself, as i just needed a Mount eventually, and sending it back and fourth gets expensive.
 .
 as for the part if its a QC error, i have to ask, do you have access to a Micrometer somewhere (decent Quality digital Calipers would also work, but its a lot more difficult to meassure with)? If so, i might give you some instruction on how to meassure if its in Specification on size (i have a guess on what the Issue probably is).
 .
 From my own testing and Reverse-Engineering of the MFT-Specification itself, there is Quite some Tolerances involved in MFT Lenses and Adapters, and Metabones Speedboosters being on the Tighter Side. So if you have any very Cheap Native MFT Mount Lenses or some of the Cheap China MFT Adapters, try to mount one of those and see, if that will mount propperly.
 .
 Krontech Customer Service in General is good, but it can be a bit of a Pain and take some time to even get some Conversation with them going. But once you manage to get a Conversation with someone from Krontech going, it usually goes pretty smooth from there (at least it did for me whenever i needed anything so far).

Here it is: https://imgur.com/a/zp0jS3s

 The Speed Booster simply will not turn more than about 10 degrees. Regular M4/3 lenses will indeed turn and lock on this mount though. And both the speedbooster and the lenses will attached to a GH6 and Black magic pocket 4k.
Well, seems normal to me from the images...
 Just asking the most obvious Question, you do line up the Dot on the Speedbooster with the Red dot and turn the Lens In Clockwise Direction (Clockwise while looking at the Camera into the Lens / From the Front)?  Also, did you Remove the Little Standoff Thing / Tripod Support Bracket on the Speedbooster before Mounting? its usually Screwed on by two Hex-Head Screws from the Bottom, and on most of the Speedbooster versions can be in the Way to mount it on the Chronos in that way.
 Other than that, maybe try to share a very short Video of it, trying to mount it and showing some Closeup of the Speedbooster Mount all around. From the Image, i cant see anything wrong with it so far...

As for the Attachments, those seem to just not work currently on this Forum, had some issues with it Yesterday myself. Contacted Krontech about it, but have not heard back from them or dont know how long until its fixed. Until then if you want to share something, maybe try to use some External File / Image / Video Sharing /-Hosting Platform and just post a link here until it works again hopefully soon.
 .
 i seen you linked the Thread where i already have shared my encounters of that Problem.
 For me i usually just make sure to save more than i need, and cut the first and Last bunch of Frames in editing.
 To line them up, if its really that much of an issue, consider using your Trigger Button to also Trigger some kind of Flash that works similar to a Clapper in early Analog Recordings of Silent Films, that would give you Clear Sync-Point and should only take up one or two Frames.
 .
 Now for the Random Mixed up Frames within the Sequence itself, that indeed is some Pretty Nasty error and annoying to fix. Had that happen to me, but it seems rather Rare on my Camera...
 If yours does that a lot, maybe contact Krontech directly via their Mail or Phone; or try some slightly older Firmware Version to see if it changes anything.
 The other Issues are somewhat easy to fix or find workarounds for, and have not bothered me all to much, but the Thing with the Random Corrupted / missordered Frames within the Sequence is bad.

Can you share a image with the M3/4 Adapter Mounted to the Camera but no lens Attached to the Adapter, where the Sensor is Visible? (Front View of Camera Basically)
 I do own a 0.64x and a 0.58x Metabones Speedbooster and have had Hands on with an 0.71x from Metabones, they all do fit usually.

Chronos User Discussion / Re: Procedure for RAM upgrade
« on: July 17, 2023, 02:39:00 PM »
Glad to hear your Upgrade went well.
 i lost pretty much all Hesitation of taking this Camera Apart, i did it way too often by now. But it can be pretty intimidating if one is to do it for the First Time.
 The Short Ribbon Cable can very easily be Replaced by a Longer one for less than 10 € Cost, those are Standard Size.
 Posted an Image of this in use in the other Thread, but the Image Link no longer works, so here is the Image again Attached to this Post. The Cable can not be directly seen in the image but was needed to make the Camera work with the Risers.
 #EDIT#: I can in fact not upload the image for some reason, contacted Krontech about it, so attachment will be missing for now, might add it later, when Attachments work again #/EDIT#
 In this Video i posted, the Longer Ribbon Cable can be seen directly:
 https://www.youtube.com/watch?v=9zUavp2P5Kw
 Would need to look up what Cable i used exactly, if someone wants to know, @ me in here, i will reply as soon as possible.

Have you tried any Recordings with Different Resolution Settings? Do those give the same or similar Results?
 .
 If they also dont give usable results, try with a Much older Software Version like 5.1 or 6.0 and see if that changes Anything.

Chronos User Discussion / Re: Fitting the Micro Four Thirds Mount
« on: June 22, 2023, 12:27:47 PM »
I've been shooting using a C-to-EF adapter on my Chronos 1.4 since March of 2019 with great difficultly.  No C to EF adapter on the market is stable enough to shoot with the weight of a the 11-16mm EF lens.  The connection continually works loose, causing the backfocus distance to change which makes the lens go out of focus and require resetting the focus.  This happens nearly every time the camera is picked up, and I have countless shots ruined by being out of focus due to this issue.   I eventually bought a rail system to provide more support to the entire setup, but even this was not enough to stop movement of the lens on the adapter.

The MFT mount appears to have completely fixed this problem. I have a native MFT wide-angle lens and an MFT-to-EF adapter using the same 11-16mm lens, both are rock solid now and I don't need to keep using the unwieldy rail system.
That Yukisoa User is a Spam Bot btw.

I suppose the bulk of my confusion comes from never using an MFT camera or lens before.   I know about the crop factor as it pertains to using a full-frame lens on a crop sensor camera, but many sources say that MFT lenses on a MFT mount all have crop factors of 2X.

 The General Rule of 2x Crop for MFT = Micro FOUR THIRDS = Micro 4/3 = 4/3" Sensor Size is true; but the 1.4 has an even smaller Sensor at 2/3" Size, meaning basically another 2x Crop on top of that / Half the Diagonal Size of MFT YET AGAIN. its a really Tiny Sensor.

15
While assuming Full Frame Format to be 36mm Wide and 24mm High of a Sensor Area ( which is not 100% accurate, cause different Camera brands use slightly smaller or Larger Sensors, but its usually close enough) and the Chronos 1.4 having a Sensor size of 8,45mm Wide by 6,76mm High at full Resolution; the Horizontal Crop factor compared to FullFrame would as a Result be 4,26x.
 In the 1.4 Manual the Crop Factor is Quoted as 3,9x, but this isnt really accurate if the 1.4 is used to shoot 16:9 Format Footage (the Quoted Crop factor is refering to Diagonal Field of View, which of course is technically correct, but wont apply unless you use the Full Width as well as Height of the Sensor, therefore Horizontal Crop Factor is more accurate in this Case)
 .
 Meaning your Tokina Lens zoomed out would end up being a Equivalent Focal Length of 46,86mm when Converted to FullFrame Equivalent.
 For anything really worth calling a Wide Angle Lens on the Chronos 1.4; you would want to have a Lens with 8 to 6mm Focal Length or even wider, especially if you use smaller Resolutions (which will Crop the Sensor even further....).
 For Focal Length that short, you will usually have a Hard Time finding appropriate Lenses For EF-Mount, using C-Mount or MFT-Mount Lenses is likely the only thing that makes sense.
 .
 If you got some Special Focal length in mind you are Looking for, i can try to see if i can find any good ones.
