I'm pretty much done with my 50mm 1.8. It just isn't working for me because the AF is too slow, and all my shots at f2.8-f1.8 seem softer than I would like. I also get more misfocuses than I would like unless I am shooting a relatively static scene.
So, what I want is:
F2.8 or faster
Accurate AF that is noticeably faster than the 50
$400 used at most.
I wouldn't hate 1:2 or better macro ability, but that is secondary to the above.
Please pick something for me, I am tired of looking at lenses! Gear is listed in gear list.
