I'm getting fed up with this lens!
it's auto focus is picky, slow, and loud.
there are no reference marks on the focus ring for night shots.
it's plastic.
no IS.
Chromatic aberration when subject is against a bright BG (birds in sky)
and its high aperture with small lens picks up little light.

It was very dark out to the point where I could only see movement, so I had to guess the focus between shots, this is where reference marks would have been nice.
the viewfinder was even darker.

But I guess that's what you get for $200, I'm still saving for a better one...
