Canon EOS R5 Unite and Discuss!

Correct me if I'm wrong, but if I'm shooting at say, 1/1000 or even higher, I don't really need image stabilization, is that right?

So "they" say; but I generally/mostly leave it engaged as most newer models can determine whether tripod mounted, or not; and I've not noted any problems leaving it on in any event.

I'd probably "mess-up" more shots by forgetting to turn it on, then by forgetting to turn it off, so I just leave it on,

I think it depends on what subject your are shooting and how long a lens you're using. Shooting go fast boats with the 100-500L I'm typically in the 1/2500 to 1/5000 range depending on focal length. I still keep IS on because it very helpful steadying the subject as I'm tracking it versus having the subject bounce around alot more in the viewfinder.

I'm looking for assistance on finding a correct setting.

I generally shoot landscape and wildlife. I have custom settings for both (C1 and C2). Both work fine. When looking through the viewfinder, both work in respects to the question I am about to ask.

I had occasion to so some indoor portrait shooting last weekend. I set up C3 for this purpose, with people eye auto focus, and manual settings for use with a set of strobes. The photos came out well, in spite of my issue.

Issue being, when focusing, for a brief moment, the viewfinder would be lit sufficiently for me to aim, compose and focus. For a brief moment, that is. Then it goes too dark. Not black, just very dim making it difficult to see whats going on, after I did the initial focus. I don't have that happen on the other settings. I've compared MENU settings on all three, and outside of the focus settings (e.g. animal eye vs people eye) I am not finding anything different.

Any thoughts? I've spent a fair amount of time going through the R5 manual, and the internet, and haven't found what I am looking for. But I may not be using the correct search keywords either.

It sounds to me it would be the 'exposure simulation' setting. The EVF is showing the exposure based on settings (shutter speed, aperture and ISO), but because you rely on flash for exposure, the set values result in an underexposed image without flash, so dark viewfinder. When using flash, you can disable exposure simulation and the viewfinder would remain fairly lit, like it is with focussing.

For your landscape and wildlife your dialed in exposure settings result in a proper exposure based on available light, hence you see a well exposed image in the viewfinder.

YES! That appears to be it. Thank you!

I have another portrait session in a month, and did not want to have to deal with this again.

A new firmware 1.7 update is now available. Changes are minimal:

"Corrected the phenomenon that, on rare occasions, the camera would not operate normally while shooting a small subject.

Fixed minor bugs.":

Two years too late for me as I've already purchased the OEM BG-R10 Battery Grip, but here's finally a third-party grip for R5/R6 that looks promising. Here's a video that compares the OEM vs. third-party (Mcoplus), $349 vs. $94:

Yes, the information is minimal. I doubt the content are. Because releasing a software has efforts, so I am sure Canon will not spend it on small changes. It's just that they will not tell you anything.

I have no idea what Canon's updating; wished they'd be more specific. I did update the firmware but have not seen any changes. That's probably about right, since whatever Canon updated has to do "on rare occasions" and "small subject."

I updated last night as well. I'm always leary for a few days after updating. I'd hate to start getting all those lockups again!

I'm going to pass.

if it ain't broke....

I was still on 1.5.2, never went to 1.6. I did my now normal process of saving camera settings, resetting camera (first option in reset), update firmware, restore settings. Seems to be working fine. I had notice that autofocus on eyes was not as good on 1.5.2 for eyes on more distant subjects than I thought earlier versions were, but it was stable. We had some cedar waxwings flocking in the backyard and it did seem to do a better job, but that is seat of the pants reaction, nothing scientific. Anyway, I’ve taken 400-500 shots with no issue sover a few sessions.
