Just my limited experience with contax planars 50 1.4: the ae versions have tight threads, which basically makes them impossible to be as buttery (some 'whispering'), compared to mm which have much more space for a thicker grease.
Also, the ae versions I had have been better optically (better) than mm. All copies were in very good condition, without any apparent faults. I didn't have any 80+ serial copies however.
but highspeed f1.4 is the reason they are not so buttery like the 1.7 both AE. I have only AE, from 18 to 135, some double(28,45, 50/1.7)for 3dstereo. at 135 i will use zeiss and yashica ML for 3DS.

ALL OF THE AE has the NINJA Star Bookeh two stop before wide open, the MMJ OR MMG they do not have ninja star bookeh. the AE versions do not have the small aperture number in green.
Not all. My AEJ 50mm f/1.7 Planar doesn't have a ninja star aperture.

Thanks again for your input
The now finished Zeiss Planar 1.4/50 C/Y Review can be found on my blog, if you have anything to add please let me know
Phillip,

Please replace "pentagons" with "hexacons".
Not many lenses have 5 aperture blades and produce pentagons. I have one; Rodenstock APO-Rodagon-N 50mm f/2.8. As it's enlarger lens, 5 blade aperture was sufficient for it's original purpose. It's one of the best lenses I have seen, but wide open either suffers from thick filter cover glass caused field curvature or just not good on C-zone. But closing down f/4 or f/5.6 gives the most "transparent" rendering and the most neutral boke I have ever seen, but the pentagons ruin it. I'm transforming this lens to fixed aperture lens (somewhere between f/4 and f/5.6) by adding metal disk with circular hole on top of aperture blades. For 2016, this lens will be my main "flower" and "close-up" lens.

I had the Apo Rodagon borrowed some time ago. Optically it was great (at least at shorter distances) but the plasticy build quality and the 5 aperture blades put me off.

I was referring to the focusing being buttery or not, not the bokeh. That being said, I worked on the lens some more, and indeed managed to get it to be really buttery, top class. It was definitely more difficult though, had to try a whole bunch of greases, also absolutely any speck of dust inside the threads makes it feel like you have sand inside, something that I haven't encountered before on more forgiving lenses (including the mmj).

Yes really crappy plastic build quality - also from usability point of view it's horrible, at least on my M39 adapter it sits so that the aperture scale points down. Also needing short extension ring and M42-focus adapter makes the whole compo looking ridiculous, but actually works pretty well.
Would be nice to have all lenses same quality and usability as C/Y Planar 50...

how about Molykote DX? its a white grease handling also low temperatures. using it in roundshot 360(RS 65/70/220) depending how much i use i can control rotating times. I wanted to tell that its better for speedy lens not to turn buttery. It depends for what purpose.

Molycote DX is probably way inferior to the easily available (and much more expensive) helicoidal japanese greases from microtools. Of course, they are charging a huge surplus just because they can (not anymore btw, thanks to yours truly who talked to the original source of those greases in japan, whom I convinced to sell the same grease on ebay at half price about a year ago).
But still, a helicoidal grease needs to have good properties in time (lots of that time may be just sitting idle, which is one of the main causes for separation). I just don't imagine fairly cheap industrial greases being up to the task. I wanted to try some expensive vacuum greases (basically no evaporation in time at normal pressure), but they were all a bit too viscous for most lenses (according to the specs at least).

If you are adapting Zeiss Contax/Yashica to EOS pls read the IMPORTANT NEWS in my new thread about adapters and chips. incl. LEITAX for some Zeiss AE-lenses not only MM anymore.
there are also news about leitax Contax/Yashica-NEX-adapter which will have a ring added to existing mount. no mount-replacement. and tripod-mount-option.
