From where did you got the information? It would be awesome if Zeiss is at least "ready" to produce them.

I doubt that we will find 500 buyes for a lens-type. In my inventory the 21 and 135 are missing.
from zeiss themselves would you like to sell your 100mm?

If there is a running poll or tally, count me in for a 21mm

I have four Zeiss ZK lenses, that I use on the Sony A7r. The 85/1.4 and the 35/2 don't really perform like they are comfortable with a 36mp sensor.
The 28/2 and the 50/2 however are my standard lenses on this camera.
I have debated whether to get the Loxia 21 (E-mount), as I was too late for the Distagon 21/2.8, but I would prefer all my lenses in K-mount, for I might go for the Pentax FF in future. Also, the larger dslr lenses are somehow more to my liking than the smaller E-mount lenses, with the shorter registration distance and the consequent large distortion on wide angles that has to be corrected with a profile. The distagon 21/2.8 is a great performer on e-mount as well as dslr.
So count me in for the 21/2.8

I was actually thinking about whether this would be an opportunity of an entrepreneur. Order two models of Zeiss lenses, 500 each, then sell them at a higher price over a longer time period. But the problem with this would be margins and a small market, I guess

Interesting that you mention that you feel the 85 and 35 aren't really up to a 36mp sensor. A huge part of the reason why I decided to get these two lenses for the k-1 is because of the STUNNING images I have seen as a result of these lenses mounted on the D800/D800e/D810. They got great ratings on DXO mark on the nikon 36mp's also... The likes of the 21/50/100/135 to have a slight edge and are better, but I really don't think the 35 and 85 are far off. There are few (if any) lenses that are available still for a pentax FF that I feel are any better than these. The zeiss 25 is another that is available that produces outstanding results as well. Its certainly up there. It also gets VERY high results on DXOmark and I have seen some jaw dropping images from it.

Heres some examples of some of these lenses on the Nikon 36mp sensors. Pretty good results on such a sensor from amongst the few FL's that are still available!

Also, whilst on the topic of zeiss lenses, if you haven't seen the pancolar 80mm 1.8, there are still a few going of this lens also! They are stunning. They are more of a classical lens that produce finely rendered, neutral tones, sharp as a tack. Not cheap, but worth a look and I imagine they would perform very well on the k-1.

If I didn't already have a 77mm, sigma 70 macro and the 85mm zeiss, I'd be getting one.


heres a good example of the luscious booked and the fantastic sharpness this lens can produce. SO much character to this lens.

Please don't buy any until i have the extra money to splurge on this lens which I love, but currently feel is unnecessary given my current line up! hehe, no, really sharing is caring. Someone please do make good use of one of these lenses on a k-1 for me!

Interesting, as the industrial versions
are rated down to a 3.6 micron pixel pitch for the 85/1.4 Planar and 35/2 Distagon,
but only 3.9 micron for the 28/2 Distagon.

hmm... the "legendary" 31mm. Its good. I'm yet to find an image that shows its as sharp and resolves as well as the best of the zeiss though. I did think about it, but I've gone with the 35 distagon instead, with absolute confidence that i've made the right decision. If I want auto focus at a similar focal length, I'll simply use the 43mm and take a step or two back.

Just another reason why the ZK 28/2 is prized - wide and fast

Well, perhaps I should add a bit of nuance. The 85/1.4 has a lot of fringing on the A7r at apertures wider than f2, but beyond that and certainly from f4, it is a great lens. So if you limit your use to f2 and beyond, it should be a wonderful lens.
The 35mm f2 distagon was my favorite lens on the K5 cameras, but not so much on the A7r. It is more of a classical rendering style lens, and can produce great images at wider apertures, portaits eg., but it is not really an allround lens, the distagon 28mm is easier in this regard, as it has a more modern color rendering, and has a less temperamental character. There is also something about the very sharp edges of the 35mm that makes it a less easy lens for allround purposes, it can be bitingly sharp. The makro planar 50mm has the more modern high resolving and transparent look.
If you like high quality (portrait) images with a classic style look and a lot of character, than the distagon 35 is unbeatable. But beware of the strong colors and sharp edges!
The planar 85 is a great lens, all the more as it doubles easily as a stunning landscape lens, but you cannot really use it at f1.4-f1.8 on a 36mp ff sensor without running the risk of heavy CA.
Of course, these are ZK mount designed lenses, and the Pentax sensor stack and raw treatment will play their part in how these lenses will perform.
Overall, I was very impressed with especially the ZK28/2 and the 50/2 on the Sony A7r (with the matching voigtländer K adapter).
The Zeiss cosina made series are lenses to last, wonderfully made and always impressive, hard to produce a dull shot with them. I regretted that I was too late for one of its best: the distagon 21. I have tried to find one for three years, but no luck....

You are not alone in that quest - they are rarer than hens teeth in K mount

It would be interesting to know how many ZK 2.8/21's were actually produced.....

I also contacted Zeiss when the Pentax FF was first announced, asking if they planned to resume production of (some of) the ZK lenses when the FF would be released, but unfortunately, they have no intention doing so.
Apart from the practical obstacles of actually ordering 500 ZK 21 distagons, it would not be such a bad idea to assemble a list of people serious about getting one. It is still simply one of the best 21mm lenses ever produced for FF, and manual focus is pretty much what people would use at this focal length on FF anyway.

The way it is going, I assume a Kickstarter solution or similar would be the best way forward.
Re the comment about the 31 quality, it was my opinion that the focal length is too close to 25. And I think as well that the 31 has better optical quality than the 25.

Hi Everyone

It has been commonly stated that Zeiss have stopped making K mount lenses. Though true in part, its not entirely true. Just wanted to throw this out there, that they actually still will if there is an order for 500 of them. Now! Who is after a Zeiss and is feeling organised to muster up a little (wait, make that a lot) of extra interest/committed buyers?

K-1 (or even just Pentax) and Zeiss.... um... doesn't that sound right do you?


Kindly,

Rob.
So counting lenses Zeiss lenses price, if your order for something like 1 million$, they'll consider it... Lol. For this price, can you have various models or do they have to be all identical?

Honestly if they really wished they would offer a service to buy a lens in any compatible mount and transform it for a high price. Maybe 500$ ? I am sure some people would still buy it and they would make a benefit on it.

Here the only possible use case for me is a distributor doing and reselling at a higher price. And still I guess selling everything at least in K mount would be very difficult.
