[Leica] Leica M lens MTFs

[Paul Roark]

Thanks, that's a good set of data sheets.

My reading of the various postings regarding the new Summarits suggests
that the 35mm might actually have a new formula, with an aspherical element
added, but we'll see.

On another forum someone had asked about the 75 2.5 I use with the Sony
a7r.  I had a copy of the old PDF that I posted for him, but I could not
find the official ones where I thought they used to be.

I wonder how Leica evaluates its sales into the non-Leica camera base.  The
WATE and everything above 50 mm is better than anything else on the Sony
(unless perhaps one has a porter to carry around the new huge Zeiss top
end).
