If this is so, I wonder how Tamron are able to continue manufacturing their Leica ADAPTALL mount? (referred to in a recent post)

Dear Francis,

I have not heard of the Sigma 50-200. Can you tell us more please?

Kind regards,

Justin

A question to clarify the discussion on the recent history of the Vario-Elmar 35-70. The f3.5 lens had an E60 filter thread and was fully made in Japan.

The lens mount was then redesigned (intro 1988) with the front barrel no longer rotating. (the optical system was not changed just the mount) As a result the filter thread size was increased to E67. This lens was made in Japan but assembled in Germany. Thus, engraved “Germany†instead of “Japanâ€.

The current (intro 1997) f4 35-70 Vario-Elmar has gone back to the E60 thread size. Is it also made in Japan but assembled in Germany?

Is this a correct summary of the Vario-Elmar 35-70?

Thanks in advance, Craig
 
Yes Craig,

I think the f/3.5 optical cell was a Minolta design and the f/4.0 designed at Solms but the cell made by Sigma in Japan and shipped to Germany for assembly.

Dear David,

There is no such thing as Leica glass. The glass lab at Wetzlar was closed in the late eighties.
