The usual Zeiss Biogon C 35mm f:2.8. I should be getting my 50mm f:2.0 tomorrow. Pics are of a late afternoon in Versailles.

Why do you guys have the problem to mount G-Biogon 21/2.8?

I have no problem with my G->E adapter (Kipon-look-a-like) and reach infinity too.
Because of rear protector of the lens I have to mount the adapter to NEX5 FIRST,
then mount the lens to the camera+adapter SECOND. My adapter is > http://www.pbase.com/kkawakami/image/127863088
Although the corners have slight colour shifting, but fixable by CornerFix program as you know.

Actually we are very lucky G-lenses have a kind of breach-mount which does not
require to rotate the lenses to mount them.

Philber - Wonderful to see Versailles shots from both 5DII and NEX system ( referring to other thread ). I must say that NEX still is a little thing of wonder. Very good result, also due to the quality lens, and the photographer. First and last shot are my favorite with lighting and color. Once again, great to see the amount of detail this set up can provide. Do you, by the way, use or see any need for corner fix ( ? spelling may be wrong ) with Biogon 35mm? I do not notice any issue, and was not sure whether that is because you have already processed them.
Congrats on 50 f2. Planar I am looking forward to see photos from it.

No, Akul, no cornerfix required. And this week, I should also be getting a Novoflex adapter for my Contax C/Y 25mm, so I should have a lot more flexibility with my NEX. The problem the NEX poses is that I am getting plain lazy about carrying my 5D II....

I bid on a Contax G Distagon 21, but bidding and byuying are two different things. If you mean my ZE Distagon 21, I have no plans ot fit it on my NEX, as I would have no way to stop the lens down.

Great shots from the NEX and the Biogon.

Philippe, that is the idea behind the NEX : as long as you put decent glass in front of it the results are good and you start not to bother with the big guns. Of course not for everything, but for this type of shooting it is the right tool.

One of these days, I will stick the ZF21 on NEX and post some shots here. The thing is that 21 on NEX feels a bit ergonomically wrong.


Philber
Contax C/Y25 would be a great focal length for 'walk around' whatever that means. Also the weight should not be too bad. I am curious to hear your reaction to the size as it would be bigger than ZM series. I see contax g 21mm for about $700 USD at KEH.com. I have a feeling that is a bit on the high side.

By the way, it sounds like there will be less and less 5DII shots from you Ha Ha, I am just giving you a hard time.

Yes, Stefan, but that same afternoon, I did take my 5DII + Zeiss with me, and the results were quite a bit better. So I have to get unlazy...

Regarding cornerfix, I am curious what the 'threshold' is in terms of focal length with NEX + rangefinder lens. Seems like somewhere between 21 - 25 mm ? There is already enough steps to get a photo being usable, and I am not a big fan of the idea of using yet another software.

I am pretty sure that 25mm is still OK. I have read conflicting reports on 21mm, and I tried 18mm, which was clearly not OK. Though, even in this case, it does not affect every shot

Here is one example of the colour shift with the ZM 18mm. Otherwise, it is a really excellent lens.

I really like the warmth in the last image. Zeiss lenses are known for being "warm" lenses - how much of this do you credit the lens vs. shooting at what, I would call, an ideal time of the day?

Rather than answer you, corposant, I let you decide. Here is a picture taken in opposite circumstances: late morning, low ceiling, fog, some drizzle.

I may be speaking out of turn, here, but I think cornerfix is a more helpful product for shooting ZM lenses on an M9, because the larger sensor is going to catch the edges where smearing/casts occur on WA lenses. I would think with the APS-C sensor the NEX has, it should only get the best of these lenses (but maybe I am wrong).

No, you are right, the larger the sensor, the more edge problems you have from a given lens. Except that the M9 is designed to nullify this problem with specially designed micro-lenses, plus software once you tell the camera what lens you are using. At least that is my understanding of this not being a Leica specialist.

I think I prefer the sunlight, but all things considered, not bad given the circumstances!

Philber - thank you for the example. It seems sky or snow field would be the tough subject for the color shift. It is a great shot by the way.

Nice Philippe. Out of curiosity, how long have you been waiting for your ZM 50 f/2? I've had one on order since the end of November... hopefully mine won't be too far behind.

Can't speak for the NEX but on the M9 it seems to be very lens dependent and the most significant factor seems to be the distance of the rear element from the sensor and angle of view of the lens. I tried both ZM 21 lenses and the f/4.5 version has extreme vignetting and red shift. I believe that lens's exit pupil is narrower and/or the rear element sits closer to the image plane. The f/2.8 version exhibits this to a much lesser degree and is almost completely corrected with use of a Leica profile. I only have two lenses for the M9 at the moment, the ZM 21 f/2.8 and the 35 C-Biogon that Philippe uses here without showing any red edge. Even when using an appropriate Leica code for it, I can usually see some slight reddishness along the edge. But others claim to have no such problem, so it could also be camera dependent, just to throw in one more variable.

I would think if you were to mount a 21mm designed for SLRs that there will be little to no red edge shift due to the much more nearly perpendicular path light rays are projected onto the sensor plane compared to UWA rangefinder lenses.

It would be interesting to see someone compare something like the ZM and ZF 21mm f/2.8 lenses.

Was checking out the "Sweep Panorama" feature on the NEX-5. Initially thought it was cool, and later just a little disappointed. Besides being jpeg-only, it is also only auto ISO -- adjusting ISO to preserve a minimum shutter speed, after all the camera is in motion while it fires off successive exposures. From the results, considering these factors, it is not a substitute for serious panoramas -- it is basically snap-shot quality. The images are noticeably less sharp than single exposures, mostly likely due to auto boosting the ISO and motion bur from camera motion. Combined with the in-camera jpeg processing and images are just blah.
Here is an example with the Contax G 35/2 mounted (at f5.6 and I'm pretty sure the horizon is not level):

Thanks for this interesting example; Lotus. I had also tried this function, and been disappointed by the results, so I am glad to know it wan't user error.

On my side, I tried the "stabilisation" yesterday in a church (daylight, with a low, great, overcast cloud ceiling. Here are two shots, one done manually (1/15s, f:2.8, ISO1600), and one with stabilisation (1/60s, f:2.8 ISO6400). The feature also alters the default settings in LR (no sharpening at all, no NR), and I am pretty sure it involves in-cam NR.I then applied PP to my liking on both. Let me know what you think...
