Some interesting pics, NEX 5 with M mount adapter and Leica lenses.
While the shots are small and reduced And the crners either cant be evaluated or are intentionally OOF, the stuff with the 35 lux looks sweet! Actually all of the lenses seem to look pretty good although I wasn't a fan of the tilted buildings with the tri-elmar.
hopefully mine will arrive soon.
Here are some comparisons of a few lenses on the RD-1.
I am beginning to get interested!
The NEX 5 with M adaptor is looking even more exciting than the RD1 for me. It's a pity that the adaptors are so expensive though, but I expect that they will start to come down in price when more are available.
There are some really nice NEX 5 images around, most taken by some very talented photographers.
In no time weŽll start seeing more afordable made in china generic adapters on ebay.
Mine arrived today and is waiting for me at home. I will post some shots once I get home and get to try it out.
These adapters aren't really all that expensive, try looking at the price of a Novoflex.
John, looking forward to your tests.
I got my adapter and here is a couple of quick test shots. One with the kit lens and the other with the Leica Rokkor 40mm f2, both at ISO 400 along with a 100% crop of each. The crops are screen shots nd the JPGs are converted from RAW with Bibble 5 Pro all default setting except for white balance set using dropper.
On my monitor it is very evident that the Leica lens is just super sharp compared to the kit lens with no sharpening beyond default applied and the distortion is virtually non-existent.
I have added a side by side comparison at 50% screen shot.

Well, the dilemma deepens. RJ was kind enough to get mine (NEX to c adapter) shipped real quick and I have it. Beautifully machined.
This is really a bargain at this price.
c ----> OM
c-----> Nikon F
c------> Minolta MD
It is also, in principle, possible (for me) to convert the c-mount adapter usable for a pen F.
Thanks for posting these, John. Quite a difference between the 'kit' (which I like for it's versatility) and the Leica lens.
Makes me wonder what can be achieved with my 75 'Cron, for example
I suspect the NEX sensor is capable of producing very sharp images with the right lenses in front of it.
I'm wondering if I should buy a cheaper Chinese adapter or wait for Novoflex. I saw your post on DPR in which you mentioned that infinity is not at the lens infinity mark. Oh well, I guess that as long as you can reach all focus points it doesn't really matter, or does it?
I'm not sure it matters but JR says that they make the adapter a little thinner than needed to make sure it will reach infinity with all lenses. Further, he says, if I want to adjust it I need to add some thickness between the silver metal lens mount that the black holder (between 0.15mm to 0.25mm) via trial and error until it is right. He says to just carefully remove the 4 screws holding it and add the additional thickness behind and screw back the plate. I haven't figured out just what to use to obtain the desired thickness (maybe paper cut to match?). I also haven't decided if it is worth the extra effort.
Here I am adding a few shots taken of my back yard with trees and I think this may be the best I have seen at displaying leaves. I will check against M8 shots of the same area and post later.
Thanks for posting these shots with your Leica M 40/2 lens.
Looks like maybe there is some smearing/loosing sharpness near the borders and the definitely the corners of the bookshelf shot. Not sure what aperture you used for the shot but hoping you shot this shot stopped down to provide enough DOF.
Can you provide a shot of a planar surface like the side of your house and then provide 100% crops of the corners and borders and the center. Just curious like everyone else how well the Leica lens works in the Sony NEX 5 system.
Here are shots of a planar surface with a test pattern. The screen shots should give you a relative idea. They are arranged as follows (first 4 are 40mm/f2 and last two are kit set to est 40mm (actual 43mm)):
First set from the center pattern, next set from upper left and last set from lower right. There was some reflection from a window I couldn't quite block out in the upper right shots but I think you can still get the idea.
I just received my 16mm pancake and will try some test shots with it for comparison.
I'm out of space as usual so I won't post the 16mm comparison; however, it is very very close in sharpness to the Leica at the center but falls off very fast and the distortion is very large where it is almost nonexistent on the Leica lens.
Thanks for taking the time, John. If I'm reading these correctly, it appears that the 40mm is in good shape. The real question is with 35mm and wider M lenses, as that is where the problems happen on m4/3.
I wish I still had my 28 ASPH as it was a really sharp lens. It put the 40mm to shame as did the 50 Cron. I will have to search for some used M mount CVs or Zeis lenses to try one out. My gut is that it will be as good or better than the Epson RD-1 which I thought was pretty good. One note is that the Leica lenses make the little thing feel like a mini-tank. The 16mm NEX lens is really light and the whole thing feels like you could easily put it in your pocket.
Thanks very much John for all your work here. Quite a difference between the Leica and the Sony 18-55.Good to see that with a 40mm lens it doesn't smear the corners or borders.
Because of the 1.5 crop factor I wouldn't expect that much vignetting even on the 28.
Can you post some 28 test shots with corner crops? TIA
The shots are from a fly screen. I am very happy with the lens / NEX combination and will use it together with the 40 Summicron and 90 Elmar-C.
If it will do the 21mm with minimal vignetting and loss of corner resolution it will prove itself to be the best inexpensive Leica replacement going.
Would be interesting to see how the Leica M8 or M9 compares in the corners using same lens but different camera platform comparisons are tough to do with all the different factors of RAW conversion and sharpening etc.
I see a big difference in the IQ of the shot between the 18-55 and the Leica 28 and 40. Keep the Leica shots coming.
I added the thickness of a piece of 24lb bond paper as a shim and it appears that I may now have infinity where it should be. I will know more tomorrow after I have more time to test in daylight. If it is too thick I'll just remove it. You need a 00X50 jeweler's phillips screw driver to remove the screws.
You might want to try using thin metal tape to shim it instead of paper.
I just didn't have any. There isn't much room to work and it reminds me of the old days of trying to cut out gaskets for carburetors out of gasket material only much smaller and more difficult.
I removed the paper spacer and replaced it with a piece of heavy duty aluminum foil. That was easier to work with though less thick so I think I may go just beyond infinity but I can't be sure without a really far off target like the moon. As I recall with my M8 setting infinity to anything closer than a star or the moon resulted in it being off. There is probably another way but I don't know what it is.
John, Your best source would be a shop that sells stuff for models (trains, planes, etc). They should have a set of thin brass shims (it costs ~4-7 Euros for a set of ~4-5 sheets here and it is from Chicago) of various thickness.
Someone should make a NEX to m4/3rds adapter. The Pana 20/1.7 looks good on the NEX. Corners are dark but it does seem to project sharp images even wide open.
My M adapter arrives Monday. I should have results with the 35 Summarit, 50 1.5 Nokton, CV 15 4.5 II and 35 Skopar early next week.
Vivek, Thanks. To the rest, I look forward to seeing what other produce.
Today I took some photos at midday on a perfect winter day, blue skies etc. On basically all photos I experienced a fairly strong purple hue shift.
Yesterday I took similar photos late in the day and I did not see any shift then, but when I re inspected the shots today I also found traces of purple hue shift.
It is not a big drama because it is easily fixable in Lightroom.
I attach a photo below for demonstration.http://forum.getdpi.com/forum/attach...1&d=1279366744
What lens were you using? There is no EXIF data with the image. The image seems a little soft like the 18-55 kit but it could be just due to camera shake from the cold winter weather.
My M adapter arrived early. Initial impressions with a few photos to follow shortly:
Basically clean bill of health, with some caveats: 35 Summarit, 50 1.5 Nokton.
Needs more testing: 35 Skopar.
Failure: CV 15 4.5.
35 Summarit: At f5.6 to f8, the results are superb at all focus distances with no corner smearing whatsoever. Wide open, the results are excellent at close focus through maybe 2/3 of the focus range; as you near infinity focus, the IQ towards the edges slowly begins to decline somewhat -- not m43-style corner smearing, but a drop-off in edge quality that becomes noticeable if you are looking for it (I will try to post examples of this tomorrow). Bokeh sometimes great, sometimes a bit odd. Bottom line: generally great at close- and mid-range focus from wide-open; by 5.6, great across the board.
50 1.5 Nokton: Same pattern as the Summarit but much more disparity wide open between close and infinity focus. At f1.5 to f2, it's really fantastic at close range and the center stays good maybe halfway through the focus range, but IQ becomes disappointing as you get closer to infinity -- edges drop off and a haze sets in over the whole frame. By 5.6, it is stellar at any focus distance. Bokeh sometimes great (esp at close focus), sometimes not. Bottom line: a great look at close range wide open, then great across the board starting at 2.8 and peaking at around 5.6.
35 Skopar: Didn't test this as much but it seemed to have somewhat more IQ degradation towards the edges at infinity than the Summarit; seemed to be very good at close range, although I like the look of the Summarit better and got bored testing this.
CV 15 4.5: Strong magenta discoloration in the corners of every shot. Also, some kind of blurring effect towards the edges at 4.5, 5.6, somewhat at f8. The magenta cast is pretty bad.
So, CV 15 aside, my initial impressions are very positive. The results with the Summarit and Nokton are much, much better than with the 18-55. So far, my impression is that the results are also somewhat better than with equivalent lenses on m43 -- in particular, the color seems deeper and the picture looks less "thin", although the m43 results are already pretty good. The Nokton does better wide open here than on m43.
So here are a few photos. These are snapshots, JPG from camera, imported into Lightroom 3, uncropped (obviously), most with no processing, I think contrast/brightness adjustment on one or two, all exported as JPG at reduced size. Lens and f-stop should appear in the file name. The failure with the CV 15 is first.
I think once we can edit RAW in Lightroom 3, the IQ is going to be very good.

-- You can focus past infinity, so the focus scale on my lenses is a bit off, some more than others. Of course, I'd rather have that than the other way around.
-- The fit on the lens side seemed a bit tight at first, and when I tried to take off the Nokton, it actually started unwinding the LTM-M adapter ring instead. After about 10 lens changes, though, it seems to have become much easier to use.
Just noticed it is possible to post larger size photos. I have to run, but I'll try to post some larger shots tomorrow, including some more detailed examples of what's going on in the corners.
