Clever people,


I'm considering getting a Carl Zeiss 50mm f1.4 Planar T* ZK lens (Pentax K mount).

The lens being manual focus, I'm in doubt if it will "communicate" exif, priority & shutter values to the camera body on a K1?

I have its 'cousin', the Milvus 50mm makro planar with my Nikon D3 where all values are passed on to the camera, so I would assume it's the same with th K mount version even if it's an older model, but would like to have this confirmed before buying.

Put another way, I have a Pentax 77mm limited lenses, one of my all time favourites. I assume the Carl Zeiss will function the same way in all manners except being without the autofocus feature?


Huge thanks in advance,

Kasper

This should be covered in the K-1's owners manual booklet.
I'm not a pentax user, so no easy answer from here.
I did have a D-200 which is a similar time frame to the pentax, and the exif data could be manually entered as above.

Hello again,

I ended up getting the 35mm f/2 instead of the 50mm 1.4. There seems to be different generations of the different Zeiss classic lenses with KAF mount - some with an 'A' setting an some without. I got the first - and there's communication between camera & lens after setting the focal length (which the camera identified as '35'mm). In essence, it works like my 7mm 1.8 lens but witouth autofocus.

It's a fine piece of engineering.
