>>4289243>how much better are pictures from a canon r5 in comparison to a 90d?The image quality has plateaued long time ago. You'll get better autofocus, IBIS and low light performance. Manual focus lenses are easier with proper focus peaking too. In the end, if you have good light, the glass matters much more than the body.
You probably should wait a bit more. R5 will probably get a Mk2 and see a more price drops in the near future.
