FA 20mm F2.8 or DA 21mm F3.2 Limited

To add to my LBA which of these 2 lens will work better with my K20D?
Which has less CA and better edge to edge sharpness? I don't care about the speed I ususally shoot at f8 anyways.

Photozone review of FA20/2.8
Photozone review of DA21/3.2

According to this the DA might have a small edge.

A zoom like DA16-45 might be just as sharp and would have low distortion at this focal length but CA would likely be worse than either of the primes.

if you find a FA 20mm F2.8 , buy it.

or buy a DA 21mm: it is a good lens too.
