Photo Forum / Digital Photography / DSLR Cameras / December 2005Carl Zeiss ZF lenses for Nikon?
Their web site has been hinting at something of that nature. I guess the question I have is, why? >Their web site has been hinting at something of that nature. I guess >the question I have is, why? In early 2006, Carl Zeiss will announce the first in a range of new ZF lenses with Nikon F mount and. I believe, AI coupling. The lens range is a joint venture between Carl Zeiss and Cosina of Japan. Cosina already makes several of the Carl Zeiss ZM range of lenses for Leica M mount plus the Zeiss Ikon 35mm rangefinder camera. >>Their web site has been hinting at something of that nature.

AI coupling went out with the Ark. It would certainly limit the surefulness of these lenses with newer F-mount cameras.

AI(S) lenses are still being sold *new* by Nikon. The S feature only works on a few models and is largely useless anyway. Perhaps you are getting confused with the pre-AI Nikon F mount, which needed lenses with "ears" to couple to the Photomic meters? They became obsolescent when Aperture Indexing (AI) was introduced. >>>>Their web site has been hinting at something of that nature. I guess >>>>the question I have is, why?

I suppose that Zeiss lenses will mostly be used on the high-end cameras that can use AI, but even so it seems that using the mechanical coupling on a new lens is an odd thing to do. We'll see, I suppose. Andrew. >But why not make them CPU lenses? I suppose that Zeiss lenses will Could be a licensing issue. (pure speculation here). >mostly be used on the high-end cameras that can use AI, but even so it >seems that using the mechanical coupling on a new lens is an odd thing >to do. We'll see, I suppose. Hey, it's another opportunity for this guy Roland, the guy who "chips" older Nikon lenses. http://home.carolina.rr.com/headshots/Nikonhome.htm Pere Kodak >>Their web site has been hinting at something of that nature.

The lens range >is a joint venture between Carl Zeiss and Cosina of Japan. Is that because Cosina already has a license from Nikon for the F mount? but perhaps not the D or G series lenses. Vater Kodak >Cosina already makes several of the Carl Zeiss ZM range of lenses for >Leica M mount plus the Zeiss Ikon 35mm rangefinder camera. Does not sound very liklely to me, AI indexing is incompatible with the metering systems on Nikon's current range of SLRS and DSLRs. > Their web site has been hinting at something of that nature. I guess > the question I have is, why? >Does not sound very liklely to me, AI indexing is incompatible with the >metering systems on Nikon's current range of SLRS and DSLRs. s/current range of SLRS and DSLRs/low-budget SLRS and DSLRs/ SignatureThat was it. Done. The faulty Monk was turned out into the desert where it could believe what it liked, including the idea that it had been hard done by. It was allowed to keep its horse, since horses were so cheap to make. -- Douglas Adams in Dirk Gently's Holistic Detective Agency >Does not sound very liklely to me, AI indexing is incompatible with the >metering systems on Nikon's current range of SLRS and DSLRs. Nonsense. AI lenses work perfectly on the F100, F5 and F6 and FM3A film SLRs. They also work perfectly on all the D1 and D2 series DSLRs, plus the new D200. They also mount on the consumer SLRs (N80 and below, D70 and D50) but the meter does not work. Precisely the point made in the last sentence "The meter does not work" That will limit saleability of such lenses definitively Of course there will be 'die hards' who will argue in favour of such limitations... >>Does not sound very liklely to me, AI indexing is incompatible with the >>metering systems on Nikon's current range of SLRS and DSLRs.

A very good and important point. -espen Signaturehttp://www.seland.org/ >Precisely the point made in the last sentence "The meter does not work" > >That will limit saleability of such lenses definitively I suspect only pro's will buy those lenses, and pro's also tend to have older, AI Nikon lenses and camera bodies that will meter with the pro's. However, it does limit their usefulness with Nikon flash systems. >Of course there will be 'die hards' who will argue in favour of such >limitations... Really? Help me understand who those die hards are, and more importantly, WHY they make that argument? Sheesh. I stopped using my Weston Master IV meter, oh, 40 years ago. Love built-in meters. However II did recently buy a used Pentax Spotmeter V [analog, not digital :) ] Abba Kodak |
