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!

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....
