The Pentax SMC-FA 31mm f/1.8 AL Limited is an excellent lens. It is already sharpat f/1.8 and razor sharp at medium apertures. Distortions and CAsare very well controlled. On the downside it vignettes quite a bit at f/1.8 sothe ultra-large max....

Its front heavy and large compared to its peers the 43 and 77
