Pentax 135mm f/2.8 IF SMC P-FA
(From Pentax lens literature) The Pentax SMC P-FA 135mm f/2.8 IF is a great portrait lens as it allows a comfortable distance between the photographer and subject. It allows for a shallow depth of field and is ideal for working in low-light conditions. It features an internal focus system to make focusing smoother and faster, and is treated with the acclaimed smc coating for maximum light transmission, sharp definition, and high contrast while minimizing flare and ghost imaging.
Pentax 135mm f/2.8 IF SMC P-FA User Reviews
9 out of 10 points and recommended by danag42 (4 reviews)very fast focus, sharp lensmodern lenses have too much plastic in their construction
For a modern lens, which supposedly is better for the use of polycarbonate material in the barrel, this is pretty sturdy. I prefer the old metal barrels, but this lens focuses quickly and accruately and produces very sharp images. Pentax's multicoating is as good as it gets, and the lens is light enough to be easy to use (another benefit of polycarbonate?).reviewed August 6th, 2006 (purchased for $270)
