EOS R5 Mark II issues with colors and corrupted images

[jasonleecs]

Hi,

Any R5M2 owner encountered a "layer" of additional/missing colour platter in your photo taken?

Initially, I encounter image preview issue where the camara states that the "current image cannot be previewed" on the camera but didn't thought much about as it was already night and I'm shooting the cuscus near the homestay. But things took a turn the next day when I'm shooting the bird of paradise. A quick preview on some of the images show symptom the night before and worst, photos with additional/missing colour platter.

As I continue to review the images, I noticed some of the images either have a tinge of colour, e.g. green, yellow, pink etc., either in in full or partial on the images.

Initially, I thought it could be due to the slower SanDisk UHS 2 SD card wasn't able to catch-up with the write speed that causes the problem. So, I removed the SD card and let the camera write to the faster Prograde CFExpress card with the sustainable write speed of 1300MB/s.

However, the issue persisted and even more ridiculous! I took the camera for a sunrise shoot one morning, instantly, the 1st shot encountered the problem describe above on the CFExpress card. Therefore, the theory of incapable card or heating is ruled out. 

Would like to hear from follow R5M2 owner if you've encountered such issues.

The camera config is as followed

Firmware v1.01 // Highlight tone priority D+2 on shooting the bird, and was disabled when shooting sunrise // Elec shutter for BOP @ H+ and Mech shutter for sunrise at single // SanDisk 256GB Extreme PRO SDXC UHS-II Memory Card with R=280MB, W=150MB // ProGrade Digital 1TB CFexpress Type B Memory Card (GOLD) with R=1700MB, R=1300MB

Thanks.

At last.

Congrats Canon. If you cannot come up with a solution at least warn the people.

From my last holiday when I import the photos to Lightroom at least %20-30 of the photos give warning and doesn't allow editing. Those photos cannot be converted to DNG files with a converter as well.

Horrible experience really. This happening since 1DX II doesn't make it innocent, in fact it's worse that nearly in 8 years such 2 big companies couldn't work together and solve such problem.

To be fair, every hardware during the early stage, it will more or less encountered compatibility issues as the real world can be very different from the lab/limited field testing since every combination is a permutations factor for possible cause.

What set a respectable brand apart is the speed and openness to resolve the problem. I don't hold both Canon and SanDisk for the cause of the issue, but the measurement would be the post incident management.

Thus far, my only complain was that SanDisk screw up the RMA replacement and expect the customer to foot for their negligence which I'm not compromising and would rather throw the SD card away.

I'm still awaiting for their subsequent reply before cutting the cards into piece and send it to their case management system.
