Price Paid:  $700.00 from Canada

Summary:
A real piece of crap. My sample had aberations in all the elements, leading to poor sharpness at every aperature and distance.

Strengths:
Really, nothing at all. I hear the AF model is quite good.

Weaknesses:
Everything anyone could think of. Optically, mechanically, awful. Poor value, poor design. I could not decide whether to smash it or sell it. (I sold it.) Every company makes mistakes. Don't make this one with them!

Similar Products Used:
Pentax everything.

Customer Service:
None needed. They appologised for their design team. I still swear by Pentax products for their price, weight, durability, and optics.
