Can someone elaborate on the EOS R5 stills 1.6 X Crop mode

I was seeing RobAmy's images in the R5 images thread and saw several that he posted as "cropped mode" that have amazing detail. I shoot a 7D MkII and was thinking that I would miss my crop sensor advantage for reach. I already crop my images from my crop sensor camera and know that if the resolution is high enough on a full frame image that it would just be more extreme cropping to accomplish the same image. I was just dreading having to deal with the large file sizes and slower workflow that would result. But it looks like the R5 has a stills shooting "crop mode" that would give the crop sensor reach, reasonable file sizes, and maybe even less work (less heat) on the X processor.

Can someone that has the R5 in hand elaborate with details such as file size....?

According to the R5 manual, it is "Approx. 17.3 megapixels (5088×3392)".

I get the impression that GAJoe was more interested in image quality than the pixel dimensions. This is something I also would be interested in hearing about. How does APS-C mode in the R5 compare to 7Dii images?

What are the file sizes?
Do the images afford cropping? To what extent?

The R5 in crop mode will have a little less resolution (17MP vs 20), a little less noise, and also has a better AA filter, so there will be less aliasing artifacts with pixel-sharp captures, despite slightly bigger pixels. The AF intelligence, however, might be the biggest practical difference, and IBIS will complement stability.

Extra teleconversion or a longer lens can tip the subject resolution in favor of the R5, of course, with or without crop mode.

Dont forget

Robamy is using 600 F/4's and 400 DO's

Glass and post processing is the bigger factor with his outstanding images v/s camera sensors

this 1.6 crop mode has very very little to factor in with great glass like this

I will second the above comment. I think most of the images that Rob has posted as in crop mode are with 600 f4 (sometimes with a TC).

Although you lose some MP's with the R5's crop mode v's the 7Dii you do have the opportunity to focus @ f/11, getting extra magnification of the subject if you use extenders.

Sorry I missed this post. I really like crop mode, comparing it to the 1dx Mark III which has 20mp file the 17mp file is really close. You can easily still crop in a bit. All my files on Flickr are sized to 24x16. I have printed up to 30" with no issues. I like having the 45MP when needed but the crop works very well. I find it pulls the subject close which helps the eye focus a bit. I rarely use it for flight because you lose some screen AF real estate vs the full frame which is almost the entire screen. There is no advantage in quality vs cropping in but when I just shoot basic things I do not need a bunch of 45MP files for nothing. Where I really like it, my 400mm f2.8 has an equivalent mm of 640mm f2.8 which is very nice.

How well do they work in crop mode ?? with a 1.4TC that 640mm become 896mm+ at F/4.....IF IT WORKS CONSISTENTLY....thats a killer wildlife set up

They work great, crop mode does not change the quality at all. The extender quality in full frame equals crop mode quality.

Funny I just used that setup last night in crop mode with the 1.4x

All with the 400mm f2.8 + 1.4x in crop mode

I like the consensus that is building on the quality of the crop mode images in these cameras. However, there are two factors that make be question whether or not mirrorless is in my future (as long as there is a choice, that is). How is the shot lag with the EVF vs. optical? Also, battery life? As one who waits for the moment before tripping the shutter, shot lag is a big factor.

Lag with the R5 is really not an issue at all for fast movement, the EOS R was awful. Coming from the 1dx Mark III battery life is not an issue either, I get 2-3k shots with 2 batteries in the grip. Battery life with the 1dx is better but not a issue in the field.

All Canon mirrorless work very well with the TCs and AF, even the M series.

I routinely use a 1.4xIII and 2xIII on my 100-400 with my mirrorless bodies (M50, R, R6). Once light goes down though, it does get a bit inconsistent. With a 2x, it also does get a bit slower, I haven't noticed too much performance degradation with the 1.4x though.

I agree. I haven't noticed anything glaringly different with shot speed after AF lock and shutter click on the R6 compared to the 5D4. The R was just slower in about all aspects, but we know that Canon kind of rushed that out anyways to introduce RF lenses.
