Canon EOS R5 Unite and Discuss!

Screen has been freezing up on my R5 also, 300 f2.8 mkii, 500 f4 mkii and RF 70 200 F2.8. Others report 100 400 mkii and RF 100 500

Seems like an issue with the R5 with any lens ,happens to me maybe once on a full 6 hour wildlife shoot, pop out battery to unfreeeze

Screen freezing

What batteries and memory cards are you using with your R5?

Also, have you updated to the latest firmware?


I've only had the screen semi-freeze on me at a wedding. Nothing important but I took a picture during the reception and it stuck on the screen for a second. By the time I reached for my cell (holstered to my side) to take a picture of it the screen cleared up again and I kept shooting as if nothing had happened, I didn't even power-cycle the camera. I was using firmware 1.1.0 at the time but I'll have to check my notes to confirm which R5 body did the semi-freeze because one body had firmware 1.1.0 and the other had 1.0.0.

I had my R6 freeze two times when shotting normally and I can make it freeze using the Canon Camera Connection app on iPad (I have not yet tried after the firmware update ). I just got my R5 yesterday and no freeeze yet.

btw only using the new original batteries.

What about memory cards?

On R6 2 x Angelbird 128 GB SD cards. On R5 one 512 GB CFexpress from SanDisk.

I just retestet on R6 with SanDisk cards and the same result. When the app is connected and I touch the iPad screen to focus the camera freezes. I will test this on R5 later to see if the same happens. Both cameras are updated to the latest firmware.

I have now tested on R5 also and it appears that this issue only exist on R6.

My control ring adapter came today!

As precious as gold these days.
I've got one coming from Asia

I still don't see how you are getting more dynamic range. It should be less. By this reply below:

The dynamic range should be half. Dynamic range is the ratio between the largest and smallest values a value can take. Going from 16K to 8K reduces the ratio by two, or one stop. There's something missing in the explanation.

The range of 8K to 16K does not disappear; it becomes extra headroom, which is the whole point of HTP. 200 with HTP is exactly the same thing as ISO 100 with -1 EC; HTP simply meters for 200 instead of 100, and tells the converter that it is to be rendered a stop brighter. It saves you from dark preview images, and having to set EC with an extra offset beyond that dictated by the scene.

In most 14-bit cameras (of many manufacturers), matte "white" is about 4000 to 8000 higher than black in the green channel, and black is 512 or 2048 with 14-bit Canons (in every color channel). That's the green channel; "white" in the red channel in deep shade or blue channel in very warm light may be 1/4 that or less. The fact is, most normal exposures without HTP don't even use the majority of RAW levels available, and HTP uses even less. Raw levels are sparely used in most real world exposures, with many stops below clipping unused.

I just looked at an externally-metered DPR studio shot with a color checker card in it from the R5 at ISO 100. The white patch, which I believe has a reflectivity of about 95%, IIRC, is 5610 (5354 more than 512 black). With a max of 16383-512 = 15871, that's only 34 percent of full scale in the green channel, and only 25% in the red channel, and 21% in the blue, and for HTP, it will be half of that: 17% green, 8% red, and 10% blue. That's how sparsely RAW value ranges are actually used in a linear scale. Even as high as 8K for white is usually a myth.

The highlighted text makes sense to me. I take pictures like that, then fix the curves and exposure in post-processing.

Yes. Because of COVID Canon couldn't hold a huge reveal event like previous years where these folks would have had a chance to handle the cameras and then vlog about it later.

So now Canon is sending units to the same ones that likely would have been invited, so they get their moment with the gear. For example Jared received everything Canon announced including teleconverters. He didn't actually preorder all that gear and then received it all already months before everyone else.

Lots cheaper this way and still the same marketing impact.

I can see this sticking in the future, if it's cost effective. There are certain youtubers out there that has the following and Jared is one of them.

wildlife guys

3:45 through 6:00 as well as 9:00-11:00----Must listen closely

If you have ever been to Yellowstone and the Tetons....this is extremely disappointing news

Advantage definitely to DSLR.

Also wondering how its going to PU BIF's that quickly appear. A DSLR can get them if you perfect the skill sets. Sounds like this will be a bit of adjustment on the R5

I absolutly agree....some of the best shots you will ever get is when you surprise wildlife. Camera has got to perform here

It will take some getting used to for sure. I would not buy the R5 or any camera without getting the battery grip because I am used to the 1D bodies and I don't want to messing around with changing out single batteries.

As far as the evf freezing during shots goes, one may have to get used to shooting with both eyes opened and track the subject with the eye that's not behind the view finder. It's awkward and takes some practice, but it can be done.

I have been shooting with both eyes open for 20+ years. Constantly amazed people dont do this

I can’t. I’ll open the left one quickly to get an idea where the subject is but most of the time it is closed.

I find it very helpful for shooting weddings as well.

Now that I have been doing it with both eyes open for years, I can't do it with an eye closed. It is almost like BBF; muscle memory isn't there to use regular shutter button as effectively.
