Here's f/7. I found out why I'd never done f/11 or f/16 -- my camera stops at f/8! RTFM a few times over, I guess. :)  Posted by Hello

Still then, it is a superb shot. Actually the sharpness of your lens varies with the aparture ... like my tele is sharpest at f/11 whereas the prime is at f/3.5

Keep experimenting! Don't call yourself a newbie, the shots are JUST GREAT!

blush Thanks. Okay, I will no longer call myself a newbie. But I still might ask some basic questions.

Such as: Why does the lens sharpness vary with aperature? Is this an easy thing to figure out?

I don't know exactly why, but I read about them and found it to be true. Generally if a lens rating is f/x, then maximum sharpness is obtained in f/2x aparture.

Hm... My macro lens doesn't have that info.

I guess I'll just have to experiment. What a shame. :)

Ahhh... found my FujiFilm's rated for f/2.8. That makes a lot of sense given my experience and your equation!
