Many people seem to own a FF camera for general use, and an APS-C camera for wildlife shooting, where the greater "pixels on the bird" should give some IQ advantage.
I have a 5D4 (FF) and used to also have a 7D2 (APS-C). I once did some detailed comparison shots using a 600mm lens on both bodies, cropping heavily into both images and comparing IQ on crops at the same field of view. I expected to see the 7D2 give an advantage, but was surprised to find the more heavily cropped 5D4 images gave slightly better IQ. I decided that this was due to the 5D4 having a 30MP sensor, compared to the 20MP sensor in the 7D2. Maybe also, the newer design of sensor on the 5D4 was giving additional IQ advantages?
Consequently I sold my 7D2 as I could not see any "reach advantage" from the crop sensor camera.
Now a year or so on the 90D is available with a 32.5MP sensor.
I am wondering whether, if I bought a 90D and repeated my test against my 5D4, I may now find the 90D giving slightly better IQ than the 5D4 on heavily cropped bird photos?
What do people think?
I'd especially like to hear from people who have a 5D4 and a 90D and have done such comparisons on cropped bird photos!
Thanks.
