Decent lens, but far from perfect...

Re: Decent lens, but far from perfect...

Maybe you were responding to me. I'm not saying your terminology is wrong. You are probably right to say sharpness, and complain about sharpness. What is wrong is to assume that this is solely a lens issue, or tells you anything about the resolution of the lens.

Resolution is a lens issue.

Sharpness is a processing issue.

Your image is not sharp. However, I can't tell if the lens has adequate resolution, as this isn't a good subject to test resolution. You need to use a test chart of something with fine detail. That can include text from a book or magazine, but only from very far away. This image is too close and there is no fine detail. Also, I don't know the size of the text.

Brick walls are popular as bricks are a standard size. However, you have to shoot them from far away, as you are trying to resolve the bricks, not the texture on the bricks (which can vary considerably between bricks!)
