Excerpt: I am a semi-professional photographer that shoots on a K-5IIs. Up to this point, I've solely shot prime lenses (with this camera), as I've never wanted to sacrifice image quality. I bought this lens to use on a wedding as a "back-up" lens, and never ended up taking it off my camera body.
Pros: Consistent Output, Lightweight, Nice contrast, Strong Construction, Very Sharp
Summary: This lens do what is made for and I strongly recomanded this. Very fast delivering and I have one questions with other bayers: Did someone receive this item without original package and boy and also without user manual and varanty list? That I have to give only 4 stars.
