Re: M-20/4 vs. K-24/2.8 ?

[Arnold Stark]

The K or A24/f2.8 as well as the A or FA20/f2.8 are not free from 
distortion, either (which super-wide-angle lens is?), but the distortion 
of these lenses is much smaller as that of the M20/f4. The perspective 
of the 20mm lenses really is W -- I -- D -- E, I think too wide for a 
general wide angle. I would pair a 20mm lens with a 28-35mm lens.
