Quote:Can't reduce the size, sure sony B) A biotar can perform better than a distagon (and vice versa) - it just depends on the skill of the designer.Small M lenses don't work so well with mirrorless digital cameras because of the glass in front of the sensor. Leica's workaround is to use very thin glass (<1mm), Canon/Nikon/Sony are around 2mm. The solution seems to have a larger exit pupil.

On the other side, the new Zeiss Loxia aren't that much bigger than ZM lenses but don't have that issue.
