p.1 #1 · New 1.0.3 Firmware Update for Canon EOS R5 Mark II?


I’ve seen in Facebook and in Canon Rumors that there is now a minor firmware update for the EOS R5 Mark II v1.0.3 but can’t find it on the Canon USA site. Is it real or a fake? If it’s real is it worth while updating? Doesn’t seem like it’s the update people were hoping for.

What does it fix?

I download without issue. I have a few zooms, so worth installing it. Not sure if anything will improve but why not.

What is not working well that people are hoping to fix, something for video? My R5 II is working just fine.
Does anyone know what item #1 is exactly?
I usually wait a few days or a week to see if FW updates have bugs.

There is a similar 1.0.2 update for the R1 also.

My guess is the temp meter pops up way early giving the false impression you are over heating at times and it is not. I believe now it should pop up more when it should pop up.

The bar has so many levels it makes little sense anyways. Why have 7 white, 1 orange and 2 red?
Nothing, yellow, orange and red indication would be enough in stills mode.

People were hoping for 4k60 fine and some other video things, pixel shift instead of 'AI upscale', apparently a fix for cold weather instant batter drain, etc.

Yawn (and frustration - where is the fix to weather impacts with new battery and temperature, 4kfine60, open gate, better focus for birds moving away from dof in pre capture, pixel shift higher mpx... )

Interesting that they're always cagey with details for certain fixes, like "AF...in certain zoom ranges".

I've owned my R5ii a few months (upgraded from R6ii) and for portraits and most wide-to-medium shots I've found AF to be quite good. What I did a lot on my R6ii, which I haven't had much of a chance on my R5ii, is birding. Especially at the 500mm range (RF 100-500L). The couple of times I did use the R5ii+100-500L I wasn't getting the sharpest shots at 500mm. This is the same lens that was tack sharp at that focal length on the R6ii.

Since these two sessions were very brief, and were towards the beginning of my ownership of the R5ii and I hadn't dialed everything in (was still learning the menus), I chalked it up to user error/new camera learning curve. For the first session that was definitely true: I had mostly stock settings. But the second session was a couple of weeks later where admittedly I was still tweaking and learning the AF settings, but I'd made several setting changes recommended by birding/wildlife youtubers, and while it did up the hit rate, I still felt like some shots that should have been in focus, were not.

Just updated to the new firmware. Will try to get out and shoot some wildlife/bird shots soon and see if there's an improvement in AF.

Since these

Let us know if you see any improvements with BIF usage. Thank you and take care.

Seriously-

Fix SRAW (100% unusable)
4k Fine 60
Open Gate would be amzing but no Canon camera has it so.....

I hope this is just a serious bug hot fix and the actual firmware feature update is coming-

Have to ask what problems you are finding with SRAW? I haven’t used it yet on my R5 II and I’m usually not concerned with reducing memory usage. Admit I’ve yet to use it on either the original R5 or the R5 II.

Roofs, lines, patrerns etc are all problematic for SRAW- It makes zero sense. Its the highest bitrate but you never know when a problem is going to show up with it.

I was filming the other day in Sraw and the roofs all had moire showing, not sure if that is the proper term for it but I ruined the video.



at 6:00 this shows some examples of it. He is spot on. If its something you needed clean video for, you just can't trust SRAW to not screw up the footage. 8k RAW is great and all the other modes don't show this problem
