Cons: Relatively slow for a prime lens. Sharpness from corner to corner only obtained by stopping down to at least f5.6 and preferably f8. Expensive. In all honesty, optically no improvement on discontinued 16-45mm f4 lens, which in the UK at least is/was less than half its price.
Pros: Extremely well made. Easy to handle and its diminutive size enables you to comfortably pack and carry two or three other Pentax primes in a small carrying case. Fairly reliable and fast autofocus. Tolerably sharp when stopped down, although Pentax RAW settings will often require some adjustment. Versatile focal length. Neutral colour rendering.
Summary: Despite what Pentax forums would have you believe, there is nothing special about this lens, except for its compact size and excellent, robust build quality. Unless size is a critical factor you are probably going to better served by a decent zoom lens. A vast improvement on the Pentax K-5 kit lens of course, but that's not saying much.
