Whew, I am definitely falling behind, hard to catch up !! Amazing works from everyone as always.
Bernd - That B/W portrait with ZF85 is really beautiful. Great rendition, capturing ambivalent atmosphere.
Lars - I truly enjoy the wide gamut of your works and subject. From impeccable flower macros to the strange cup-o-noodle-like structure to serene buddhist images.
Dalmass- Great texture and detail capture of steam locomotive. Love the color very much.
prosep - beautiful cherry flower. I am struggling to capture decent one.
Alkanphel - Great little pebble. Love the pov.
Bob- Congrats and welcome to NEX club. Too bad you don't have ZF lenses, which could be used on NEX I am very drawn to the second shot. Super detail puncutated by red umbrellas. Great shot.
Carsten - How about field curvature on 50MP. Is it playing any role in the focus transition at all ? Lovely citroen by the way. Love the period of those design. Streamlined metal body.

Akul, as far as I can tell, the field is pretty flat most of the time, apart from the extreme corners, but really just the last couple of mm. I don't understand why Zeiss would not have made it just a touch larger to avoid that. Makes no sense.
I love the Citroen DS as well, beautiful car, and very advanced for its age.
Just got my 35/2 ZE. So far I really like it, but I'll have to examine photos more.
Annoyance - I've found out that the infinity setting on the lens is actually slightly past infinity focus, which I'm finding to be highly annoying - why the hell can I just focus straight until it stops at infinity?
Is this a common problem with the 35/2 or Zeiss in general? I verified this with live view magnified 10x and it's fairly easy to see with the naked eye at around 30 ft or so.
I don't know why it bugs me so much, but it does. Maybe because I just paid $1100 for a manual focus lens that has infinity slop like an AF lens
I hope I'm wrong here and this is normal.
Some shots (almost SOOC, no sharpening, etc. White balance tweak)
alkanphel, excellent POV. As rji2goleez mentioned, 3D feeling is there; although it's not like that I fully understand 3D.
Almass, excellent colors, sharpness.
rji2goleez, great details.
Lars, excellent shots, as usual.
mortyb, love the bright blue colors.

partitura, I'm no expert, but BW is really good as far I know.

cputeq- 30 ft is not far enough for 35 distagon's inifinity. You'd need to test with subject much further away. # 1, # 3 are quite a lovely shots.
alkanphel- great texture love the grain
Gotcha yeah I tested it with further stuff too and it focuses past.
I found some blurb online about people saying some ZE lenses will go past inifinity to allow for expansion, but I think I'm going to write zeiss and ask. The lens stops dead-center of the infinity mark, but it's definitely not in focus at infinity (far trees at 100+ feet).
Cputeq, I have owned 7 ZE lenses, and what you are experiencing is not unusual. My 5DII had to go in for a shutter replacement, and, when it came back, it was not "adjusted" the same as previsouly. My guess is that this is the cause for lenses going slighly past infinity: to cater to camera tolerances. As to what this means in real terms: nothing. I just "learn" where infinity is on each lens, and go there instinctively, rather than "flat out".
Have fun with your new lens! It looks like you already are...

Yes, it is a common problem. Also my ZE 35 (on a 5d mkII) shows the same issue and it is well discussed by Lloyd Chambers in his Guide to ZE/ZF lenses. Lloyd states that it is not a lens issue but an issue of the combo lens+camera, that even at f/8 cannot give optimal results if you focus ay infinity stop.
Lloyd writes also that similar problems were found with ZF21+Nikon D3x.
IMO the combo ZE21+5dmkII has no this issue.
I haven't tested other lenses, but Lloyd thinks that it is a common problem with high-res cameras

I actually have a subscription to Lloyd's but I wasn't aware he had talked about past-infinity, though I had read his issues with slight mount / lens misalignment in ZF and ZE mounts.
If this is fairly typical, though, that's fine and I've almost pretty much figured out by memory where infinity is. I asked Zeiss last night about it anyways, so I'm interested in hearing what they say.

Actually I think that is by design to accommodate for a range of temperatures. At high temperatures the lens will expand and it will affect the position of the infinity stop. Any lens, especially any metal lens that has the mechanical infinity stop dead on may not be able to reach infinity at a different temperature.

You think so? I've only heard about this being the case for super tele's. They're also often painted white so that they heat up less in the sun (which would make them expand). I think the heat expansion of a 35mm would be negligable.
I think so. If it was a question of poor production tolerances we'd see a spread in the other direction as well (i.e lenses that can't reach infinity). I have 10 Zeiss lenses, 5 ZE's, 4 ZM's and one adapted. All except one (the 35/2 Biogon ZM) go slightly beyond infinity. The 35 Biogon is dead on at optical infinity at the mechanical infinity - or at least within DOF wide open.
It's very unlikely that I got 10 flawed lenses in a row, so it must be by design and a tolerance to variations in temperature is the only thing that makes sense.
Do your ZE's also focus beyond infinity on your 7D? On how many bodies did you try them? It was rumoured that Zeiss originally said they didn't want to make lenses for Canon mount (until they came with the ZE line) because of the sloppy tolerances of that mount (on the cameras' side I presume). If there is some truth in it it would make more sense to me that they would focus beyond infinity simply to take the tolerances in the registry distance of Canon bodies into account (to be on the safe side).
I am very drawn to the second shot. Super detail puncutated by red umbrellas. Great shot.
