R5 Mark II artefacts in photo

Picked up an R5ii last week and finally got the opportunity to test it out. I admittedly haven't figured out all of the best settings for shooting - but I did notice all of the photos except for the initial two have the same bands / borders on the left and top edge. Any idea what these are? They seem to show up on every photo regardless of lens used (RF, EF adaptor, manual lens...) Do I have a faulty product, or have I overlooked some setting? I'm assuming it's a setting as all of the pictures are taken on the same day and the initial two seemed OK. This is a JPEG render from the RAWSee bordersSee borders

Almost all Canon raw files look like that, so it is normal. Called masked pixels/optical black and are useful to set the right black level or to remove row noise.

This should be from my Canon EOS D30 from 2000.

It means your software needs to be updated to crop it out. If you see the masked pixels other things may also be off, like the right black level. Should be around 512 for low ISO and 2048 at higher ISO. If all your raw files show a strange colour cast, then your black level is probably 0.

ovejitamorada,

Welcome to the site.

I have been following a thread on another site with people that are having the same issue. What software are you using to view the images? Have you viewed them in Canon DPP?

This is a quote from that thread:


The issue is with Adobe Camera Raw, not the camera. If i load the shot into ACR the fringing appears, if looked at in other apps there is no fringing. Which leads (me at least) to the conclusion that is an ACR issue and not the camera. Fringing appears when viewing in bridge also. When i looked to import it into LRC, it looked fine before import, but fringing shows once imported.

The overall thought was that software without current/update software profiles display the band.

I'm not sure if this helps but thought the information may be useful.

Greetings,

Interesting.  Almost like letterboxing on both horizontal and vertical axis.   

Someone needs to test this in DPP v4.19.10 or provide us with a .cr3 sample which can be viewed and converted.

Thank you! You were right it ended up being a viewing problem, and after installing the correct plugin on Photoshop I was able to view everything properly. Thank you for the help! 🙂
