My T7i is so good...

Would it have been better if I purchased a Canon 90D instead of two Canon T7i (800D) cameras (even though it was still less money)? How about the Canon EOS R camera? That one looks excellent, but it is more expensive.

Well, if you consider the following DXOMark measurements , it would seem that the T7i and 90D are already pretty close to one another, while the EOS R has a significant dynamic range advantage.

First, there's a caveat that the link compares the 77D, which is considered equivalent to the T7i, and the M6, which uses the same sensor/processor as the 90D.  If you accept that equivalence then you see the T7i and 90D have effectively the same dynamic range from ISO 300 to 3200 with the T7i holding and advantage at lower ISOs and the 90D pulling slightly ahead at higher ISO - but not by very much.  The EOS R on the other hand is easily 1 to 2 stops ahead on in the ISO 300-3200 range.  After all, the R is a full frame camera, while the others are APS-C.

So if you're looking for better low light performance the EOS R wins hands down.  But I can't see a reason to buy the 90D on ISO performance alone - although autofocus, burst rate and ergonomics may be important to you as well.

What I can't tell, and I'd be interested to hear, is whether or not a newer camera like the 90D will deliver a clearer, sharper and better color image than the T7i, given that the specs don't tell the whole story.

Thoughts?
