Beginner Question - Limits on a lens
1

Here are three images taken today using a Tamron 17-50 mm lens on a Canon 90D

In all cases the lenses were stopped down and the shutter speeds were relatively fast

Minimal cropping.

Question - for the soccer scene and the kayaker - can a lens taking an image from a decent distance expect to be sharp if I crop to a tight image? Is there a limit to sharpness from a lens taking a photo a decent distance away? The focus points were on the subject.

I am trying to understand the limits of what a lens can produce

thanks for your patience

Mark
