1D X Mark II Owners Unite! Discuss & Post Photos

I just arrived home this morning from a 2-week non-photography trip. My Canon 1D X Mark II has been tucked away patiently waiting for my return.

Low and behold, within an hour of arriving home, Phase One has released Capture One Pro 9.1.2 which brings RAW and Tethered support for the 1DX2. Talk about just in time! I'm downloading the update as I type this and thought others who use C1P might want to know that it is available now.

Cheers,
Bryan

I'm tihnking it helps to rule out the image processor but not necessarily the CFast card slot and associated specific module(s) and/or processor(s)

Which is why I didn't explicitly say that it ruled out the camera. But you are correct, there are various subsystems within the camera that would need to be ruled out.

So I performed some other tests last night but I couldn't use my flash testing tool on the CFast card.

After formatting in camera, I copied 16GB worth of 1DX raw files to the card with my computer then copied the files off, imported into Lightroom and built standard previews and all the files looked ok.

After formatting in camera I then went outside, with the camera set on Raw+Jpeg, writing to both cards and took a bunch of pictures, copied them off, built standard previews and all files looked ok. I'll keep these files on the card and continue to reimport them to see if they degrade on their own.

If the card does in fact have bad sectors, which I am fairly certain of, I suspect the wear leveling algorithm in the flash controller will cause the errors to show up "randomly" as the controller systematically writes the files to the chips. Most controllers have the ability to mark bad sectors but formatting usually removes that.

FWIW
I've taken 3000+ photos with the standard sandisk 64 GB Cfast card and reader and have had zero glitches.

It's not a wedding camera where one would expect raw shooters to proliferate.

Highly disagree with this school of thought. Probably the best wedding camera Canon has ever had in its line up.....By a Mile

Agreed ^^^^

Coming from 5D3 this camera is a game changer, shot two weddings already and the fast and accurate AF makes huge difference, not to mention the high ISO performance..... dark churches, no problem!!! I am so happy to use the 1DX2 not for sports but as a wedding photographer.

I know I showed some early skepticism about this being a good wedding camera ,thought it was going to be too loud, maybe not enough pixel density, but know that I used it this last Saturday in my first wedding - holy f'ing crap - it is awesome - put a 24-70 on it and you have 80% of the pictures with a 98% AF hit rate - from a wedding perspective - that is money. I am glad I also had my 5DSR as a second camera for super rich pixel density portraits, but if I had to pick one camera and one lens on earth to shoot a wedding, it wouldn't even be a close decision - 1DX II with a 24-70 F2.8.

Another user here with a CFast problem and this time with a Lexar 3600x 256Gb card.

I first ran card through a H2testw test using a Lexar CR1 reader and USB3 to check whether genuine and it performed OK.

Test finished without errors.
You can now delete the test files *.h2w or verify them again.

I formatted the card in camera and shot around 300 frames saving RAW + large jpgs. Perhaps 1 in 50 jpgs were corrupted. I checked the RAWs from the corrupted images and all opened in ACR fine. I re-formatted first in Windows, then in camera and tried the same test again with about 200 shots and 3 jpgs were corrupted. On the 3rd test I tried 2 one minute videos on standard setting. One was fine and the other had a few bad frames at the beginning of the sequence and 4 out of 120 jpgs showed as corrupted. I cannot say about all the other RAW files in my tests apart from the ones I specifically checked as I only open the ones I wish to work on after viewing the jpgs..

I didn't try the Lexar Full Format and Refresh tool as I didn't know it existed at the time so I returned the faulty card for a refund. I have since taken about 1200 further shots with a standard 1066x 64Gb CF card with no problems at all.

I am now awaiting the Sandisk 64GB Canon promotion CFast card and will stick to standard CF cards for the time being.

Man, I hate hearing about these problems with the CFast cards. I hope Canon and the card manufacturers can get to the bottom of it quickly and figure out what is going wrong.

I have not taken my set-up out yet except for a 20-min backyard test, so I don't know if I have the corruption problem yet.

Bryan, please a nutshell on what is going on. I'm far away and no access to the 1Dxii....what is going on?
I played with the 1DXii before flying off but only with a compact flash card and a battery from my 1Div.
We've been on the move almost constantly and i can't read all the forums.

Well, I would chalk this up as card problem. Because if it turns out to be a camera issue (from the built-in CFast slot), you know Canon would replace it under warranty without any hesitation.

I'm using the 256gb Lexar CFast card and *knock on wood* no issues at all whatsoever. Over 926 RAWs and I'm good. No evidence of image corruption.

I don't have a link but someone on FM posted that the only CFast 2.0 card that has been tested and apparently certified by Canon is the Sandisk card included with the bundle. In addition, the Sandisk reader should be used. I've read that Transcend and Lexar are a problem which isn't a Canon problem but, the CFast 2.0 card manufacturers issue. If I hear anymore information, I will pass it on.

my problems are with the Sandisk card & reader that came in the Premium pkg "bundle" with the camera...soooooo

Someone should use a CFAST card that has exhibited these issues in camera, plug it into the included card reader and X-Copy a huge folder of big RAW images FROM the computers FAST HD (like SSD?) to the C-Fast, and see if any corruption happens then.

This will help to rule in or out if the issue is strictly card based, or if the issue only occurs between the interface between camera and card.

A few yeaars ago I had the same problem with my new 5DIII and CF cards. The same corrupt files as shown up in this thread. I was advised to replace the card reader which I did with a lexar reader since I only use Lexar cards. The problem was solved and I never had any corrupt files again.

I've used the reader & also have downloaded straight from camera & have had problems with both on same files...

Ditto

I was talking to A noted LA photog who had the D5 and was getting usable shots at 32000 ISO that his assistant with the 5D3 could not get. And the shots were very usable...... Usable 25000 ISO is a game changer. This was from the first wedding i took it to.....6400 in really crap light ...looks really good to my eye for available light at 6400.... I had shots at 16000 that were darn impressive with available light.......12800 on the new sensor is 4000 on a 5D3...dream come true for wedding photographers. the focus was on grandma
