[paisatge]

Is f2.8 the fastest available "speed" for 21mm and 25mm (M / screw mount)?

thanks. seems like they mentioned everything except Zeiss....

i dont think i have known of anything faster...
its going to 1) be hard to manufacture with such big elements and 2) the light fall off on a recessed lens design (typical of RF) is going to be really bad (i assume)

ok,.....eyeing on the Zeiss 25mm Biogon f2.8

Would you rather get a 21mm Leica or Zeiss?

thanks! will have that in mind. any idea how much can it cost 2nd hand?

quite a bit of money i would think. Honestly if u're looking at slr lenses though, sigma do a 20 1.8 at about 600+ SGD. The olympus is tiny though. U're in Barca right? If i see one in the EU i'll let u know.
