26mp A7CR apsc image vs 26mp a6700apsc image

I generally, want to be able to crop to a 4K resolution, 3840x2160, an 8.3 MP file

If we were able to shoot an A7CR, in apsc mode, and compare the resulting 26 mp image to an image shot of the same exact subject, at the same settings, to an image shot using an A6700, would there be any difference?

Would the 4k, 8.3 MP crop from the FF sensor produce any better IQ, color, etc? Could we see the difference in the cropped results from an APSC sensor vs a FF sensor?

If you used the same APS lens on the A7CR and A6700 the 26mp images scaled down to 8.3mp images should be indistinguishable from each other.

the a7r4 sensor is not the latest a6700 sensor tech, the sensor tech of the a6700 is the same as the fx30 pro video sensor.

Sony A7CR should give you a slightly better image quality. I can think of 2 reasons:

1. A6700 has AA filter

2. A6700 does not support uncompressed RAW files

Whether you will see the difference is another matter.

Uncompressed is not any better than the Lossless Compressed option the A6700 offers.

Not sure what's being asked, it may be me interpreting the questions wrongly?

Would this be say like using the aps-c 70-350 on the two bodies, then cropping the resulting images to 3840x2160, say a small subject at some distance, or, taking the full res images and processing, then resampling on export to a 3840x2160 jpg for viewing?

Either way, my impression is it's unlikely there'd be a consequential difference, that one could see.

I've never done controlled, direct comparisons between my A7Riv cropped and my A6700. Casually, both have been used in a couple of the same places with different lenses and when I've processed them and view on screen at 3840x2160, I'd be hard pressed to tell which camera was used.

I get the feeling there might be other features or functions in the A6700 and A7CR which could be considered. The A6700 has a full mechanical shutter, perhaps different sensor read out times, processes video differently. It may be that a steady unmoving subject might have different results than a subject with a lot of motion, or lighting types, things like that.

OTOH, the A7CR offers the ability to go the full 61 mp.

I'm confused about the advantages of starting out with 61 MP vs 26mp.

Suppose I use my 70-200mm f4 II lens on both the A7CR or A6700, my final cropped image will be 8.2 MP (4K). How will the final cropped image be different if I start with 61MP or 26MP? If the Final image is 8.3Mp how is there an advantage to a 61MP sensor (forget the other features included in the A7CR vs A6700)?

Thanks

If you don't consider all the other features and factors and have a steady, non-moving subject, with heavy cropping, there's no advantage to speak of for the larger sensor cropped that much.

If you were to put both cameras and the same lens on a tripod and take the same shot, and 200mm isn't long enough, and you need to crop down to a 3840x2160 cropped image, you aren't likely going to see/get a significant difference between them. While they are different sensors, the performance is so similar, it's not likely to make a difference in use - unless you go to things like a fast-moving bird wing, golf swing, mixed lighting where there might be flicker or banding sorts of things.

If you crop after the shot, in post processing, there's some flexibility in moving the crop rectangle around the larger 61 mp ff sensor area (9504 x 6336). Going to aps-c mode or putting the lens on the aps-c body (6192 x 4128), from the same spot, the crop rectangle is centered. either way, you are cropping down from the original to get to the 3840x2160 so that seems a remote chance of happening. You could move either rectangle around some in editing.

I believe from a noise reduction standpoint, resampling from 61 mp to 3840x2160 might give a little less "noise" than resampling from 26 mp. However, especially with noise reduction software, I think that falls into the "technically it's there but in real use, you won't see the difference" side of things.

You could try Photons to Photos https://www.photonstophotos.net/

and do a photographic dynamic range chart of the A7Rv in aps-c (doesn't have the A7CR) and A6700 https://www.photonstophotos.net/Charts/PDR.htm

and see that the results for that testing method are essentially the same, the results overlap. Some argue the method/results but there, the A6700 and A7CR cropped to aps-c would be the same.

The A7CR and A6700 both have the same pixel density. So a DX crop at 26mp from an AC7R file will be IDENTICAL to a 26mp A6700 native file.

The advantage of the A7CR is that you have a 61mp FF camera with an A6700 "built in" for free.

All Sony cameras support uncompressed Raw files (unfortunately).

the thread hints towards extracting stills from video

As almost every lens performs better towards the centre, the lens used might make a difference. An image taken with a FF lens viewed in crop mode, might be sharper towards the edges than the same shot taken with an APS-C lens. The APS-C lens edges will show the edges as seen by the lens whereas the image taken with the FF lens on a FF camera and cropped will show the same image but the seen image edges will not be from the edges of the lens.

It will depend on the performance of the lenses at the edges and of the F stops used. This performance changes from lens to lens.

Whether or not the difference would be perceptible? I have no idea and neither have I ever seen this tested.

No, it's not. The A7CR shares a sensor with the A7R V.

The A7Riv, A7Rv and A7CR have the same sensor. The A7Rv and A7CR share a newer processor. The A7Rs have a bigger body so have some pluses from that compared to the smaller model. The later processor provides for the newer menu and the enhanced focus tracking and focus stacking, etc. The two larger bodies have full mechanical shutter.
