Zeiss lens question

[Steve Mack]

If I buy a Zeiss 50 mm SLR Nikon mount, do I get to keep Matrix metering with my F100? I know that I lose autofocus, but what about the other functions?

Thanks to all who reply.

With best regards,

Stephen

Yes, the matrix metering is built into the camera, not the lens.

Steve is right about the metering.
There are two versions of the Zeiss in Nikon F mount. The original which allowed aperture changes with the ring on the lens only.... and ZF.2 which has a chip in it and allows aperture changes by either the ring or by the camera dials and wheels.

You can check out my website for pricing if you like.

Somewhat related, but Rob is a terrific guy to deal with...a solid supporter of analog. I have no connection or financial interest in his business, I'm just saying.

FYI/FWIW, meters in an SLR judge the light by what is projected onto the ground-glass in your prism.

Or through a separate optical path, using light split-off the light going to the viewfinder.

Touché!

just a quick clarification since it may not be clear... w/ the ZF lens matrix metering on the F100 does not function, w/ the ZF.2 lens and its CPU, matrix metering is possible. also, if you want aperture ring control w/ the ZF.2 lens, make sure to set the F100's custom setting 22 to [1].

What is the difference between ZF and ZF.2 lenses?
The ZF.2 lenses are an enhanced version of the ZF lenses. They feature an electronic interface (CPU). This CPU enables the ZF.2 lenses to support all important operating modes such as shutter priority, aperture priority and programmed auto exposure or manual exposure settings even on non-AI compatible camera housings. Photographers no longer have to set the parameters in the camera menu as the lens now transmits standard data such as focal length, speed and the aperture setting to the camera. This data can then be viewed in the EXIF data of each picture.
Furthermore, the silver fork coupling is not available on the ZF.2 lenses. For this reason, you cannot use light metering on older cameras (F, F2, Nikkormat, etc.). The ZF.2 lenses have a mechanical lock on the aperture ring to lock the aperture ring at the lowest setting and prevent unintentional adjustment while taking pictures.
For technical reasons, the ZF.2 lenses do not have a half-step aperture lock between the lowest (stop position) and the second lowest aperture setting. This guarantees reliable recognition of the automatic position. The lowest aperture on the ZF.2 lenses is orange to emphasize the automatic position of the aperture ring.


And a bit more

For details regarding metering modes and further functions, please check the camera´s manual. The ZF.2 lenses accord to the Nikon AI-P standard (manual focus lenses with CPU).

In contrast, with an F6, you can enter the data of a non-CPU lens, including a ZF, into the camera and use matrix metering.
