Anyone else have this POS lens? :lol:
The build quality sucks (fantastic plastic), but the photos come out looking decent :)


Here are some reviews:

I owned it for a month. It was OK. It has some good optics, but the AF was terrible, and the MF was not implemented well. I had a hard time getting consistent results. Here's a few test shots that came out OK.

The pictures look pretty good considering how cheapie the lens is :lol:

And yeah you're definitely right about the inconsistencies. Oh well

Honestly, in hindsight I wish I would have kept it. It really did have some great optics and it was more fun than the $100 I got for it.
