Canon R6 Mark III ISO & Dynamic Range Performance Review - Canon Rumors
December 3, 2025 - So if Canon has improved the cooling of the camera between successive models, it could be that after prolonged use, the EOS R6 Mark III may actually deliver superior results to its EOS R6 and EOS R6 Mark II predecessors. However, in practical terms, unless you continually photograph in the upper boundaries of the ISO range or sensor dynamic range, the differences are not vast, and in practical terms and you most likely will not notice it.

Canon EOS R6 Mark II in-depth review: DPReview | Photography News, Gear Reviews & Community
Canon EOS R6 Mark II
One minor functional improvement comes from Canon's OVF simulation mode, which debuted on the EOS R3 and provides a more SLR-like display experience. On the R6 II, this feature doesn't benefit from the higher dynamic range display found on the R3, so it's a bit less compelling. The EOS R6 II arrives in one of the most competitive parts of the market, facing off against some very capable competition. We think it rises to the challenge.
Rating: 91/100 ​

So just to clarify, R6ii is the best choice for lowlight out of the current R lineup?
R3 has a slight edge (1/2 stop or less I think) due to the BSI sensor, vs the FSI sensor in the R5, R6, R6II, and R8, but I don't see a practical difference. More on reddit.com

Used R6 vs New R6 Mk II
The original R6 is still a fantastic camera despite being superseded. Most of the significant upgrades in the Mk II version pertain to video use—there are only minor differences between stills shooting with the R6 and R6 II. Unless you're planning extensive video use, there's probably not much to be gained in spending the extra GBP1200 on an R6 II. More on reddit.com

r/canon on Reddit: R6 or R6 Mark II
June 9, 2025 -

I'm planning to upgrade from a 250D to an R6 or an R6 Mark II. I mostly shoot landscapes, but I'm also planning on shooting sports, events and more videos. Here in Italy the 1st gen R6 retails for 1400€, while the Mark II costs at least 1800€. Does the Mark II have any substantial upgrade over the Mark I that justifies the higher price? Like better ISO performance, better dynamic range, better IBIS?

r/canon on Reddit: Used R6 vs New R6 Mk II
May 9, 2023 -

Hello, I have been an Canon RP shooter for the last year and am considering an upgrade to either the R6 or the R6 mk ii. Reasons for upgrading would be, IBIS, longer battery life, more comfortable form factor, dual card slots, and better dynamic range. I don't currently do much video but like the idea of being able to do video in the future if I choose to. One of the reasons I am considering the original R6 is price. I've noticed that used R6's have dropped in price significantly since the introduction of the Mark II, as expected. Especially in the UK where I am currently living, Park Cameras has a used R6 for £1,559, in "Like New condition." Whereas the R6 MK II is currently retailing for £2,779. Is it worth still considering an original R6 in 2023? Am I missing something?

November 2, 2022 - Its autofocus was often unreliable, the buffer struggled with longer bursts, and its sensor wasn’t any different than the one that was in the 1DX Mark III (which means it had its limits when it comes to dynamic range). It had its strong points, but also its weaknesses. Overall, it was average. You didn’t seek out the R6, you got it out of compromise. I can say with confidence that the R6 II is not average. It does not feel like a compromise. Canon has successfully given the R6 series an identity.

February 8, 2021 - The Canon EOS R6 Mark II is the mid-cycle refresh of the Canon EOS R6. While the Mark II does offer some notable improvements and quality-of-life upgrades, they're very similarly performing cameras overall. Some of the updates include a higher-resolution sensor with a faster readout speed, an updated autofocus system, and video quality-of-life upgrades like no recording time limits, no 4k crop, and better heat management.

r/canon on Reddit: My experience with the R5 and R6 II
April 12, 2024 -

In December of last year I got myself a R6 Mark II to replace my EOS R. After using it for 3 months I gave it to one of my family members because they needed a camera, and I wanted to justify an upgrade to a R5 anyway. After a month shooting with the R5 here are some of my experience, hopefully this helps you decide between the two cameras.

Auto focus, the R6 II never managed to miss focus even in dark light and fast moving subjects and always held that focus, the R5 while still very good, is worse, most notably it locks onto the subject slower. But it’s not a big enough difference to be a deciding factor for me.

Image quality, in terms of photos, the R5 is better most of the time. More details, more (little) dynamic range, much more ability to crop. The R6 II does have less noise in lower light, but once again not enough of a difference to be a deciding factor, for me.

Video, for my uses, the supersampled 4K60 on the R6 II is much more useful than the 8K on the R5, so for me I actually like the R6 II better for video, but if you want 4K 120 then the R5 is it.

Build quality, coming from the EOS R, the R6 felt much less “solid” in my hands, while the R5 feels similar. And the EVF on the R5 is a higher resolution which I really like.

Overall, for my uses I much rather the R5 simply due to the build quality and image quality, but if I was a sports photographer or something similar I’d probably go for the R6 II.

According to measurements carried out by DXO Mark, the sensor in the Canon EOS R6 provides a maximum of 14.3 EV of dynamic range (DR). DR is defined as the ratio between the highest and lowest brightness a camera can capture.
