Quote:"Only" 21mm f/2.8? Sounds pretty good by me.The 20mm f3.5 tests badly at PZ MFT distances, but performs better at normal "infinity" distances. And you are right, corrections make a lens bigger.Besides, it's probably optimized for IQ, and outright compactness was probably not on the agenda. Compare the performance of the ZF 21mm and the Color-Skopar 20mm - they were both tested here in the Zone - and you'll see why. But I'm sure you already know it all.
I meant the "only" as in 21mm f2.8 is not spectacular, so the lens is not remarkably small. But the lens sounds good to me too. B)
