Pentax 50mm f/2.8 Macro SMC P-FA

Users of Pentax film and digital cameras can use this lens, with its full image circle, and digitally optimised optics with SMC coatings to reduce flare....

Very versatile lens, useful not just for macro, but also portraits, landscapes, etc.

This is a 10. Wonderfully made, solid and durable. Nice focus ring, large enough and easy to grip. The throw is around 270º. It makes for slow AF, but creamy MF. The focus clamp helps with MF. A focus limiter would be nice.
