Speaking of which, would the autofocus system of my camera be another issue? Because I believe that I achieved the sharpest image (using the watch as a test) by manually focusing. The difference is barely noticeable except when viewed at 100%, but it made me wonder if there's anything I can do to optimize AF accuracy? For instance, I use an AmazonBasics UV filter.

What mode of focus acquisition do you use?

I typically use One Shot autofocus, but have also experimented with AI Servo. I've read that AI Focus isn't reliable or is generally rubbish.

Good advice re cheap filters and hoods. I'll replace my filter with a better one. As for the hood, I'm not sure which to buy. Is there a specific form/shape I should look for? Or would a generic 58mm lens hood suffice?
