I’ve spent lots of money on what I understood was a great lens, but I am not satisfied with the results I am getting. Do you think I have a bad copy, or am I doing something wrong? To give you a little more information, I use a Canon 80D with a Canon 16-35mm f/4 L IS lens. I mostly shoot landscapes with maximum depth of field for extra sharpness.
The problem is that the extra sharpness just isn’t there. Any ideas?
