The best advice I can give is please don't bother chasing "the best" DA limited, buy the limited at the focal length you "need", and the speed you "need". That's what it's about. I couldn't care less if Pentax made the greatest, sharpest 200mm F/4 macro in the world, for me it is next to useless. I have almost no need of 200mm, f/4 would be too slow even if I did, and I have zero interest in macro photography. So even though the A 200/4 macro slaughters a FA*24 in the test chart reviews, I'll take the FA*24 every time because I "need" 24mm and "need" f/2... tests be damned.
