Canon EOS R5 or R6 & why

I am sure there are many more like me on the fence.
I for one would like to have the solid resolution of R5 that can compensate for the limited reach.
Rest of the differences are not so important (at least for me).
While I do prefer the mode dial on R6 over the top LCD, that may be another point to R6.
However the sheer less than half resolution is pulling me back from R6.
On the other hand the cost difference of almost half the price of R6 for R5 does not look justified either (considering just the resolution advantage)

What are your thoughts?
If you were on fence for some time and bought one vs other, what are the boxes you checked?
Let's keep the availability factor aside (due to which you may have opted to go for R6).

Appreciate your inputs.
Cropability of R5 is what will compensate the limited focal lengths for the bird and wildlife.
So how far can we stretch R6?
Could you post some extreme crops with either camera to help decide?

Thanks to @Dave63401 for posting a comparison in this post.

R6 for me as I dont need the resolution and print large but the low light sensor used is needed for me.
I am considering the 1DX3 and R6 though .

OVF for long events as staring EVF for long period of time make my eyes kinda tired ....

I have my 5d4 for more resolution when needed, but the R6 works well in most situations.

Also resizing the R6 up to the 5d4 resolution doesn't really show that much difference.

45MP resolution & 8K video. To me at least, those are the big selling points of the R5, so if you don't feel that you'll take advantage of those features, then save yourself a ton of money and go with the R6.

For my own use case I went with the R5 because I'll potentially use it for birding someday, otherwise I most certainly would have went for the R6... and I'll level with you, I have a tiny bit of buyers remorse I probably bought too much camera because until I start using it for birding (which may never happen) it's mostly going to be used by my wife for her portrait/lifestyle/por​trait photography, and I think she'd have benefited more from the low light capability than the extra resolution (over the EOS R we had previously). Oh well, the die is cast, I'm sticking with my choice and am looking forward to capturing some great photos going forward.

Here's what my reasons are from another thread:

Totally agree about the cropibility factor. Even with 8K video, which I do not do, you have 35MP frame grabs

I too keep flip-flopping. My other reasons is the EVF (5.7MP vs 3.6MP).

Why get the R6? $1400 less, two SD card slots (CF express are so expensive). If the R6 were at least 24MP it would be a no-brainer...but Canon knew that

I forgot to mention the bigger pixels of the R6 equals better low-light performance. The R6 can focus at -6.5 EV vs -6.0 EV on the R5. Is that a BIG difference?

I found the lowlight performance with AF astonishingly good on the EOS R6. Even with an EF 100-400mmL II lens PLUS an EF 1.4x III Extender I was able to focus on seabirds at night under a partial moon. The EYE-Detect AF worked with some interruptions but it did the job. The EOS R6 does have larger light-wells and that makes a difference. Normally that -6.5EV requires an f/2.8 lens (or faster) to function in super low light.

Two images taken seconds apart (handheld and with JPEG) using the EOS R6 + RF 85mm f/1.2L USM lens on the day of release.

OK, OK...you've convinced me LOL! Now if I can only find an adapter in stock! Oh wait...I'll jump next year and hopefully that won't be an issue!

It the extra dough is affordable I think the R5 is the right choice. The low light performance is outstanding and the ability to crop creates great flexibility.

Thank you all, and very good points.
Looks like R6 is taking the cake.
Based on latest rumor, may be R6 now and the APS-C (assuming it has all the good stuff from R5/R6) with a new sensor of higher density & low noise could be a choice.

This is exactly my thought too when considering R5.
If one does not lug around the heavy tele primes (that will make your wallet lighter), the extreme cropable sensor could be the alternative.
Especially for the bird photography.

I went with the R5 for the 45MP. I love having a crop mode of 17mp file. Using my 400mm f2.8 in crop mode gives me the equivalent of a 640mm f2.8 lens, just wow to me. The R5 with the 400mm f2.8 is just about perfect for me with what I enjoy doing. I love being able to go in tight in crop mode and then go full frame at the touch of a button and be ready to get flight or more environment. A big thumbs up for me.

Thanks Rob for your insight.

Hi Rob, about the crop mode.
Is it any different than manually cropping the frame in post.
I assume the crop mode will use part of the sensor and that could have same effect has you taking the full frame and cropping it in post.
I was bit confused so asking.
