Gordon Laing from Camera Labs has completed his review of the Canon EOS R5. Instead of reviewing the video performance of the camera, his review focuses on stills photography. The Canon EOS R5 looks to be a great one.
From the autofocus to the competitive dynamic range, the Canon EOS R5 will likely find its way into a lot of photographers’ bags.

These reviews always make me want to spend money....

I was convinced the R6 would be the right entry point for me in to the mirrorless realm. But these R5 reviews are tempting. I need to see some more R6 reviews to change my mind back! :) Its more financially my speed too.

Rolling shutter "noticeably superior" to the R6. Well that's quite an accomplishment for a 45 mp camera

Here's a chart showing the dynamic range compared to other cameras. The R5 is excellent. https://www.photonstophotos.net/Charts/PDR.htm
Yeah it beats even A7rIV, there was a discussion in another thread. There's a caveat though: the low-ISO metrics are coming from images with noise reduction applied. It looks like the R5 does some noise reduction on raw files in camera.

That's a decent review, although I was surprised with noise comparison made on jpegs. It's basically useless.
Not really IMHO. I'm not interested in the amount of noise, I'm interested what I can get out of low light situations. And while actually seeing less noise in a comparison might be satisfying in some way, knowing that I can have an ISO 12.800 picture processed with no noise visible benefits me more.

Why there is a jump around 400ISO?
I remember hearing that the algorithm changes at ISO 400

...looks like the R5 does some noise reduction on raw files in camera.
Ehm, it's not RAW any longer then.

You can apply arbitrary amount of NR on raw files depending on your taste and target image dimensions, so the noise comparison is most valuable if done on raw files before any noise reduction is applied.
Out of camera jpegs have some unknown amount of NR applied in camera, so noise comparison on jpegs actually shows how nice NR algorithms are in different cameras.

For those who were talking about R5's Dynamic Range...
Now add the specs (top AF, IBIS, 12/20fps, 8k Raw, 4k HQ), RF Glass and the colors Canon provides and then come and tell me that Canon has not the the best hybrid system out there!! Expect a few firmware updates that will extend record times and reduce cooldowns. Im telling this mostly to myself who cancelled the preorder and now I have to wait for sometime...

that makes zero sense, a raw file is not completely raw? sure, ok

It's as raw as you can get. Whatever processing the camera may or may not do is a black box to the user. Complaining that CR3 is not "raw" is just semantic masturbation as long as it's not possible to make the camera output anything more raw than what we already get.

Depends. If the camera can actually have a measure of actual sensor noise and subtract it from the data the image is still RAW, in many ways a better RAW.

Anything not based on real noise measurement but on algorithms trying to detect what is noise and what is not is a different thing.

Why hasn't anyone mentioned the bulb-timer? That's handy stuff...

Set to Bulb, dial in your calculated exposure time, set self-timer and Bob's your uncle. No crappy IR remotes or cable remotes or mobile phone apps.

No, the measurebation is on Canon's part for messing with RAW in order to come out better than Sony in NR comparisons.
