A small (in fact, the smallest of all systems) fifty dollars with an aperture of 1.4. Autofocus, by the standards of Pentax, works quickly and accurately even in low light. It's soft enough wide open that it makes you think of shooting portraits, but it turns out that the bokeh is not that great compared to 77 lim. Extremely sharp starting somewhere from 2.8. Nice and very reliable design. The overall impression is extremely pleasant.
