Incredibly loud AF
Sticky focus ring
comment:This oddly build lens has been a great surprise.
I have tested it against the Tamron (which I love) and the sharpness is on par when stopped down (the way macros are supposed to be used). It's AF hunts a lot less and is equally precise. Colors are the same.
If I could buy two more of it, I would, but it is not widely available.
Love this little gem and hope it will keep working for a long time in despite of the awful build quality.
A must have have for macro beginners.
