k-hawinkler Posted May 7, 2012 Share #81 Posted May 7, 2012 Advertisement (gone after registration) Yup, the Sigma 30mm got excellent reviews indeed. However, there certainly is no lack of quality manual lenses for the NEXs, considering the Leica and Nikon lenses that work well. Link to post Share on other sites More sharing options...
Advertisement Posted May 7, 2012 Posted May 7, 2012 Hi k-hawinkler, Take a look here NEX-7 + Summicron . I'm sure you'll find what you were looking for!
asoares Posted May 7, 2012 Share #82 Posted May 7, 2012 I use the Nex 7 with an older 35mm Summicron for a very nice compact walk around camera. Great manual Leica lenses with real manual focusing and real manual aperture control are a very nice addition to the modern Sony body and sensor. Some of the wider lenses have some softness in the corners but medium and longer lenses yield spectacular detail. The very accurate framing provided with all the lenses is a treat, but especially the 90mm and 135mm. Focusing with magnification is the most accurate focusing I have ever used. Hi Joe, I have a 35mm summicron v4 pre-asph and I am thinking in buying a nex7 for it. Which version is your summicron? And how does it performs regarding the known issues of color cast and softness in the edges? Thanks in advance, antonio Link to post Share on other sites More sharing options...
brian Posted May 7, 2012 Share #83 Posted May 7, 2012 I think the problem seems to be with the 35mm I have which is the latest Summicron 35mm Asph but strangely enough on film this lens performs exceptionally well in the corners but because the rear element is close to the sensor it creates problems with a none Leica camera. I will still probably buy the NEX 7 though because the problem is only really noticeable with the lens wide open in landscape or sky scenes which I do not photograph much and I have almost never used this lens wide open for landscapes. Cornerfix will solve the problem anyway although it softens the corners. I think if one is type of person that gets niggled by little things probably it is not a good idea to buy the NEX 7 but if you are the type who tries to make the best of what you have and find it easy to weigh the goods against the bads then the Nex7 seems to be a good cheap alternative with lots of possibilities with other none Sony lenses too Hi Joe,I have a 35mm summicron v4 pre-asph and I am thinking in buying a nex7 for it.

sandymc Posted May 7, 2012 Share #84 Posted May 7, 2012 Cornerfix will solve the problem anyway although it softens the corners. No, it won't. Really - it will amplify noise in the corners to the extent the corners need to be lifted, but softening is something different. Sandy Link to post Share on other sites More sharing options...
brian Posted May 7, 2012 Share #85 Posted May 7, 2012 OK I had just read it makes the corners lose resolution by photographers who had used the software. I really do not think noise in the corners is a great problem because a good picture for me is good content with clarity within the area of interest which is almost never in the corners on a landscape or city scene. I saw many photographs taken with a NEX 7 tonight by a guy who was using a NEX 7 with the lens in question and they looked good. I have 5 Leica lenses and I know that the other 4 will perform well with the NEX 7 and the one will not perform well at the corners wide open in a lens I very rarely use wide open. I have handled the NEX 7 and I enjoyed holding it and I liked what it had to offer over the other none Leica alternatives so I can see no reason to be put off a 90% positive reaction by a problem that in reality will only constitute a negative reaction of 3 to 5% Should I want total perfection I would have never lived from photography because perfection is a personal interpretation and if it is achieved there is nothing to strive for. No, it won't. Really - it will amplify noise in the corners to the extent the corners need to be lifted, but softening is something different.

BJDrew Posted May 8, 2012 Share #86 Posted May 8, 2012 OK I had just read it makes the corners lose resolution...Should I want total perfection I would have never lived from photography because perfection is a personal interpretation and if it is achieved there is nothing to strive for. I found that setting Cornerfix to ignore the vignetting (it's modest and noise really isn't a huge issue if you're not printing at 4ft+) and only to address the color shifts has largely done an impressive job. If I'm printing at 13x19" for display, I may have to spend a few moments with the eyedropper tool and curves in Photoshop - but honestly, considering all the time spent with M8 files getting the colors right, it's a dream. I really see no corner resolution difference between the M8 and NEX-7/Cornerfix with the Voigtlander 21mm f/4... And I may have 3 photos out of 5,000 that a small change in corner sharpness wide open would matter. From a practical standpoint, Cornerfix is a nuisance, but a very nice solution, even for pixel peepers. Link to post Share on other sites More sharing options...

algrove Posted May 9, 2012 Share #88 Posted May 9, 2012 The Sigma 30mm is getting rave reviews on the Nex 7 and it only costs about the same as a Leica lens cap. LensRentals.com - NEX-7 Lens Imatest Results I'll take a US$30 lens. Where did you say you bought one for that? Link to post Share on other sites More sharing options...
Washington Posted May 9, 2012 Author Share #89 Posted May 9, 2012 Daww Gone! Damn, I have one of them-thar 30mm Sigmas for my Nikon and forgot all about using it on the NEX….. got the NEX to Nikon adapter too. Hey, what can you expect? I’m an old fart with brain rot: really.

JeTexas Posted May 15, 2012 Share #92 Posted May 15, 2012 I was so close to pulling the trigger on one of these until I started reading about the video overheating problems. Some people aren't getting more than 5 minutes at a time before it shuts off from the heat. Seemed like an almost perfect solution, but I'm back to waiting.

mobr Posted May 23, 2012 Share #93 Posted May 23, 2012 Hello just found this thread. i want to buy a Nex5n or Nex7 for travelling and as digital back for my R-lenses. Are there any expirations about using Super Angulon R 4/21 Vario Elmar 21-35 3,5-4,5 Asph Super Elmar R 3,5 15 Are there the magenta problems with the 7? Is the 5n the better solution? a solution with Cornerfix? Thanks for infos Bruno Link to post Share on other sites More sharing options...
colinet Posted May 24, 2012 Share #94 Posted May 24, 2012 I got the NEX-7 body a few weeks ago and the Voigtlander adapter, but since I got Sony's Zeiss 24mm f1.4 (which my Leica dealer reckons is better than any Leica lenses!!) I haven't got round to trying any of my 3 (28mmf.2, 50mmf1.4, 90mm f.2 )Leica lenses on it. The NEX-7 and the Zeiss are fantastic. If only they'd bring out some more Zeiss lenses for it.

brian Posted May 27, 2012 Share #95 Posted May 27, 2012 I have since bought the Nex 7 since I last contributed to this thread and I do have the Summicron 35 mm Asph lens as well as the modern 50mm Summicron, 90 Summicron APO as well as the 135 older Tele Elmar. I originally had fears about the Summicron 35 Asph lens because of the bad reports I had heard about this lens with the NEX 7. I posted privately to a member on the Rangefinderforum and to a professional photographer who I both new had this lens in combination with the NEX 7 and they both replied the problem was nothing to worry about and it performs well. I can now report that all my lenses perform fantastic on the NEX 7 but the problems with the Summicron Asph are slight colour cast on some landscape pictures wide open but strangely enough it does not reveal this problem on all the landscape pictures with lots of sky at the same aperture. Are there many photographers who shoot landscape photos wide open I am certainly not one of them. Cornerfix will solve the problem as well as Capture one. I have realised now that many of these bad reports one hears about lenses not performing well are not always to be taken seriously and are on occasions more an indication of the photographers personality than the performance of the lens itself. The Nex 7 is a wonderful camera and it performs well with all my lenses and it is a dream to use Leica glass on the NEX 7. I will add though if one has wider lenses than the 35 mm lenses the results could be worse than what I have experienced because on some of these lenses the photos I have seen with the NEX 7 did appear to be more extensive but then again not all of the lenses.

Washington Posted May 27, 2012 Author Share #97 Posted May 27, 2012 A slight color shift is corrected in Lightroom in 5 seconds... all cameras set to automatic white balance will do this from time to time. Link to post Share on other sites More sharing options...
brian Posted May 27, 2012 Share #98 Posted May 27, 2012 I agree if there is a slight colour shift it it not a problem to remove and if you pay a lot for your equipment I think it it is logical that you will do a little post photo work on your shots in digital because the possibilities are there and if it is necessary. Purists might say no but if one shoots jpg the camera does it for you anyway. I have only noticed a slight corner cast on the 35mm but I suppose if I spend hours looking for faults I could probably find some kind of fault in every lens but if I ever did get to that stage I would throw away my camera and buy a good microscope.

Joe S Posted May 27, 2012 Share #99 Posted May 27, 2012 Color shift problem appear with wides and some standard lenses like 35 on APS-C. That is the accepted internet dogma, but as Brian points out.. ".I have realised now that many of these bad reports one hears about lenses not performing well are not always to be taken seriously and are on occasions more an indication of the photographers personality than the performance of the lens itself." Cornerfix is a great tool that eliminates the color shift problem for me. There is some softness in the corners with the 21mm and 15mm Voigtlander lenses, but in actual large prints I have found there is very little to choose between the M8 and the NEX 7 in the corners. That may not be the case for those engaged in endless pixel peeking and eternal gear comparisons but I believe it to be the case in actual photographic prints.

lct Posted May 27, 2012 Share #100 Posted May 27, 2012 Vignetting and color shifts are well documented facts with 35mm and wider M lenses on the Nex-7. The way photogs decide to live with such issues is another story. Link to post Share on other sites More sharing options...
