La Leica M monta i Leitz e non gli Zeiss.
Non parlo di Leica M come macchina fotografica ma di baionetta Leica M, Cosina produce gli Zeiss (baionetta Leica M) per la telemetro Zeiss Ikon.

Cosina assembla, dal momento che non produce lenti .
Sono pochissimi i produttori di vetro ottico: Cosina non mi risulta tra questi, e non certo per Leitz. Le ottiche Leitz sono made in Germany e made in Canada.
Come ho detto prima non produce vetri per Leitz dato che li produce per le Zeiss Ikon.
Copio/incollo un estratto da un'intervista fatta a Kornelius Mueller (Marketing Manager della Carl Zeiss Germany)
Domanda:
Why are the lenses to be manufactured by Cosina in Japan, and should photographers be concerned about a reduction in optical or build quality as a result?
Risposta:
We want the ZF lenses to be available for as many photographers as possible. This requires a price which - although reflecting the high quality level of the lenses - does not render them luxury items which only a tiny few people ever will find access to. Also, for industrial useage, the price point has to be in line with the Nikon lenses to be replaced by ZF. We therefore decided to use Cosina in Japan, that same factory which is producing the high performance ZM lenses, the ZEISS lenses for Leica M mount. We are sure that ZF lenses made in Japan deliver a performance even better than the ZEISS lenses for Contax RTS. And those were found superior by numerous Nikon and Canon photographers, clearly superior to what they had available for their own cameras.QUOTE(giannizadra @ Apr 29 2006, 09:22 AM)
PS. Con tutto il rispetto, tra un Nikkor e un Cosina non avrei dubbi...

Nemmeno io avrei dubbi... e non voglio provare gli ZF... giusto per non farmene poi venire di dubbi
