Zeiss

Some news from Zeiss.
First they will change the name on their lenses from "Carl Zeiss" to "Zeiss"

Second news is a bit more Pentax oriented.
You can now get the 13 industrial lenses they have in ZF (nikon) in M42 mount and the 25, 50 and 85mm lenses made for infrared are also avaible in M42.

You can sadly not get them at the normal photography store.

Nice, M42 mount is good - though I love the auto aperture feature of the KA mount lenses. Still - M42 can be used on Sigma cameras as well...

In the press release, I like the term "large area sensor" for 24x36mm.
Avoids us having to use the persistent F-words "full" and "frame" on this forum!

Yeah M42 is certainly good for these kind of lenses, very sturdy mount and future proof because they like you say can fit on most camera's.

Have been thinking to only invest in these kind of lenses for the future.
I can throw them on my K5 and on my collegue 5D and when who knows, maybe when we buy a video camera they will certainly also fit on those.

Indeed since the term full frame has a different meaning on a forum that is aimed at medium format camera.
You have true digital 645 sensor but also some like in the Pentax 645D that are slightly smaller so they use crop for then and FF for sensors that are 6x4.5

That's the small format, though

Nobody is saying it's large or medium format

Large area are sensors around these ranges "very" large is the next step but i ain't sure when a sensor is called that.

It is but it's understandable.
Who on this forum has a modern Zeiss for the k-mount (bought in the last 10 years), you can probably count them on one hand...
The M42 market is much larger.

I have a Zeiss ZK 35/2 and it really is a stunning lens in terms of the image quality achieved, and the ability to change the aperture on the K5 e-dial is a real bonus when using TAv mode.

The reason not many people on the forum have the Zeiss ZK lenses is three fold - first they are expensive, second they are becoming increasingly difficult to find, and third there are Pentax equivalents that are as good, or very nearly as good - particularly the limited lenses.

I certainly enjoy using my ZK35

Looking at Dr Nasse's blog

http://blogs.zeiss.com/photo/en/wp-content/uploads/2011/12/en_CLB41_Nasse_Le...s_Distagon.pdf

it appears that the new Distagon 25/2 already has almost optimal IQ at f/2 on APS-C.
Under those circumstances,
the M42 version would be fully usable on a Pentax DSLR with an M42 adapter,
no need to stop down unless you wanted extreme depth of field,
or a slow shutter speed for motion blur.

Yeah the limiteds are great.

What i mean is that i understand why they are dropping the K mount though, like you also say it's only a very tiny market for them.
The bonus ofr the aperture is indeed great but not essential, these lenses are manual focus so the high speed kind of photography is not what they are made for. So the lack of that is not hurting them much. For me to fit it on almost every camera is a bigger bonus.

For Pentax equivalents with the superior MF of the Zeiss lenses,
you have to go to legacy lenses,
which are often harder to find and more expensive than the ZK were.
For example, my ZK 85/1.4 was a lot cheaper than the prices I saw for the A*85/1.4.

Looks like universal mount will be the IN thing again...
Works on any sort of camera system from NEX, Fuji X, to Canikony/Pentax/Samsung, and FF.

Hopefully (and I believe it will happen), some enterprising folks will buy these lenses for industrial 'use' and divert them to photographic sale.

Also, the color rendition is quite different, more modern with the Zeiss 85/1.4, and there is a lot less pronounced "bokeh fringing". Good thing about the Zeiss lenses, is that even though the design of the ZK lenses is mostly quite old, the coatings are very modern, and I feel the lenses are quite suited for digital. I had less of that feeling when I used the Pentax K and M lenses.
