FA31, no doubt. but the K28/3.5 and K30/2.8 are closely behind. at same aperture speed, they are completely equal optically speaking. clear advantage of the FA31 is fast aperture and AF.
DA21 is not a joke. the optical sharpness and contrast is outstanding all over the frame once you reach f5.6. is a great lens even at wide open if you use it for center isolation shots because it's very sharp at the center. I think you haven't really used nor tested this lens.
I don't think the FA24/2 is terrible. I believe it is just not worth it's value right now. I think it's cheaper K24 predecessor performs a lot better than it though.
Definitely agree on the gap.
from 20 to 31 it's quite a step IMHO. It's like 31mm compared to 50mm on FF/film. It's manageable and well spaced gap but it IS a gap. Add to it that my version of 10-20 only does f5.6 at 20mm and it leaves me with nothing wider than 31mm for available light (and this is probably bigger reason behind my drive to get something to bridge this gap, than the mm difference itself!)
I can't comment on 21ltd as I never had it, but I'm not planning to purchase it anyway, I saw FA20/2.8 on sale in marketplace though, I may think of that one... but anyway, many lenses are sharp when stopped down to f5.6! I'm not doubting the qualities of 21ltd, I know there is many people who like this lens, it just never caught my attention seriously enough....
And as far as SMC xx 24s go FA*24 is really pricey but more than that it's practically unavailable in UK!!!
Now to this story of K24 (and to my understanding A24 is the same optically) being better. How good is K24??? I did give it a go but my MF skills are not the best, is it worth second look? It is for decent price from reputable seller and it is in good condition for 30odd years old lens...
AND: anybody has experiences with the Tokina 20-35/2.8 is it worth £300 in mint condition???
TIA
