FA*24/2 wide open

At wide open, the 24/2 is quite soft. The bokeh render the light source into slightly donut shape, which is normally not desireable. However, the lens still give very good color and the vignetting is acceptable. Nevertheless, f/2 at 24mm is considered as very fast, and the little drawback should be acceptable because when you need the speed at wide angle, it's the only choice in Pentax.

I havn't compare it with other 24/2 lens thou.
