jmahto Posted March 11, 2014 Share #4381 Posted March 11, 2014 Advertisement (gone after registration) I was thinking more about a direct comparison with the same lens on both A7 and Nex 6 actually, disregarding the different angle of view Gerry Sent from my GT-I9505 using Tapatalk I will be interested to know the same as well. I currently use M9 + NEX6 and for 28cron and 50lux I have to use f5.6 or higher on NEX6. Somehow CV15 works nicely on NEX6 (after LR's flat field plugin correction). BTW, 90mm and longer lenses are fine on NEX6 and I read that they are fine on A7/A7r as well. Although I get less shutter shock and 10fps with NEX6. I am not able to see any reason to switch NEX6 with A7/A7r. Link to post Share on other sites More sharing options...

Guest polygamer Posted March 12, 2014 Share #4382 Posted March 12, 2014 I am not able to see any reason to switch NEX6 with A7/A7r. Hi, many pros and cons of NEX-6 vs. A7 boil down to APS-C vs. FF, discussed here Sony A7 and A7r Review | Sans Mirror — mirrorless, interchangeable lens cameras | Thom Hogan under Final Words. So, people like myself, who have an M9, NEX-6 and A7 might ask themselves which body/adapter/lens combination is optimal. Link to post Share on other sites More sharing options...

Guest polygamer Posted March 12, 2014 Share #4385 Posted March 12, 2014 Quite a surprise for a fast low cost WA lens not from Leica, I would say. The ZEISS Biogon 2/35 and the SONY A7 are simply not a good combination ... (The NEX-6 vs A7 comparison is not forgotten;)) Link to post Share on other sites More sharing options...
gyoung Posted March 12, 2014 Share #4386 Posted March 12, 2014 Thats pretty good, shame that is so big and heavy. Do you have a Summicron 35 by chance? I remember someone else (Thomas Chen?) doing some with the 35/2 asph which showed it pretty good at medium distance, but appeared to be a bit soft at the far edges at or near infinity.

Hi, that is the reason I take the Nokton rarely with me. The ideal and typical Leica lens has the size of the Summicron 2/35. Writing of which, I only have version 4 bought in 1988 with my Leica M6 "starter kit". So, I wanted to use a more recent lens. When I tried my Summicron on the A7, I was quite satisfied with the results. However, it showed tiny dark vignettes, even at f8, and unpredictably. With my 21 Leica mount lenses, it simply takes time to try them out. I shall use my Leica Summarit 2,5/35 for the "ladies' swimwear test" next ...

gyoung Posted March 13, 2014 Share #4388 Posted March 13, 2014 They have Leica M mount, and thus M owners have them to fill gaps not covered by Leica's products. That is reasonable IMHO, lets not get carried away by 'not invented here' tunnel vision. Gerry Sent from my GT-I9505 using Tapatalk Link to post Share on other sites More sharing options...
gyoung Posted March 13, 2014 Share #4389 Posted March 13, 2014 Here we have someone putting a lot of time and effort into sorting out queries of interest to many leica lens owners, ie if leica lenses such as the 35 Summicrons work poorly with this camera, are there any related lenses which will, such as the voigtlander or zeiss items with m mount. I don't know how this relates to your problems but you sound like a child who has been told off so sounds off about other's 'misdemeanours'. There is a sytem for reporting posts that concern you, for my part I am sure the moderators can do their job well enough on their own and would only report abusive or profane posts rather than trying to interpret rules Gerry Sent from my GT-I9505 using Tapatalk Link to post Share on other sites More sharing options...

Guest polygamer Posted March 13, 2014 Share #4392 Posted March 13, 2014 So, what do we make out of the differences in border sharpness in landscape photography? In the good old days of analogue photography, they might have gone unnoticed, because enlargements were done rarely. I used to watch my slides presented by my Leica Pradovit, and was happy. I cannot remember getting up form my chair and looking into corners ... So, everybody must decide how relevant differences in border and corner sharpness are, unless one is doing documentation or digital surveillance. P.S.:@3D-Kraft.com: I am working on a polite reply to you recent contributions. This takes time. Please, watch this thread! Link to post Share on other sites More sharing options...

For Leica newbies CF lenses were calculated for the curvature induced by cardboard mounts. Soft corners could be avoided this way to some extent.

ferdinand Posted March 13, 2014 Share #4398 Posted March 13, 2014 An extraordinary amount of experience here with A7/A7R. I am about to purchase a Sony for use with my limited collection of R glass (19/2.8 V2, 35-70/4, 80-200/4). I am leaning toward the 7 for electronic first curtain and also because I think 24MP should be plenty. My concern with 7R is shutter vibration, although I haven't finalized my decision . Any comments on pros/cons of 7 vs 7R would be very much appreciated. The R 2,8/19 performs very good with the A7r and the 4,0/35-70 and the 4,0/80-200 are not very critically in terms of sharpness. Look to my short test of the A7r with Leica R lenses (It's in German) Leica R Objektive an der Sony Alpha 7R - Systemkamera Blog Link to post Share on other sites More sharing options...

So, everybody must decide how relevant differences in border and corner sharpness are, unless one is doing documentation or digital surveillance. P.S.:@3D-Kraft.com: I am working on a polite reply to you recent contributions. This takes time. Please, watch this thread! I recently did a 'slide show' of a mixture of digital (Nikon) and scanned film (Leica M6) having taken both cameras on a trip. As I looked at the pics on the flat screen monitor, and on the HD television I realised that it was probably the first time I had seen my film shots with both centre and corners sharp at the same time! Even using the Pradovits and Colorplans over the years its rarely possible to get slides flat enough for that unless glass mounts are used and they give far more problems than they solve IMHO. It prompted me to do some simple tests my self, comparing what I could get on film with the various lenses I have, both for Leica and Nikon, those photos with the 21 asph are disapointing to me, and follow what it seems the 35/2 asph. does. I know the 21 can do quite a lot better than that on film, scanned. So it seems that SLR lenses are better than these, with a few extreme exceptions such as 21/1.8 and 35/1.2 Voigtlanders and maybe the Summilux 21 and/or 24 all of which are bulky, heavy, and in some cases expensive, and unnecessarily fast for the stuff I do. The 40/2 Voigtlander Ultron seems impressive, and I would hope that the 35/2.8 Elmarit R would be good, as it was when I used it on film. But that leaves super wide, plenty of evidence elsewhere that some old MF 20s and 24s do quite well without being too bulky, but it means taking extra lenses around if you want to mix with film M cameras. Even so that might be a good option compared to APS-C, where it seems the 21/2.8 might not do too well in the corners, and that as a 'normal' wideangle, the only M mount option for superwide (at a reasonable price) is the 15 Voigtlander and opinions on that on Fuji and Nex are mixed at least! I wish Ricoh had persevered with the GXR!! Gerry Link to post Share on other sites More sharing options...
Guest polygamer Posted March 14, 2014 Share #4400 Posted March 14, 2014 Hi, Gerry, I stopped using film from 2003 on, "when I went digital". And I still remember the plop the slides made in the projector. So for me, these days are gone. I always liked compact, pocketable cameras, maybe that' s from my motorcycling days, where space is at a premium. (Had a couple of ROLLEI 35s therefore.) So, for me using SLR/DSLR lenses is not an attractive option, although I have more than 40. With lens hood, most of them are too big for my taste, apart from the Voigtländer Ultron 2/40, which is the only DSLR lens I might use on the A7 now and then. Now, coming to my experiences with my UWA/WA lenses on the M9, NEX-6, A7: Voigtländer 5,6/12: M9: so-so, NEX-6: good, A7: usable, coloured corners sometimes despite app Voigtländer 4,5/15: M9: no, NEX-6: app, A7: very good with app ZEISS Biogon 4/18: M9: good, NEX-6:good, A7: good Voigtländer 4/21: M9: no, NEX-6:good, A7: good with app ZEISS Biogon 4,5/21: M9: no, NEX-6: needs app for pink corners, A7: pink lower middle despite app Leica 2,8/21 ASPH: my best 21 for all! Leica Elmar 3,8/24 ASPH: good for all ZEISS Biogon 2,8/25: good for all Maybe, I should stop here. Of course, there is the problem of corner/edge softness, which is clearly discernible on the A7 with many M mount lenses. Last Sunday, I went to Frankfurt with my Voigtländer 15 and 21. I found these two ideal for travel pictures in a city. And easy to pocket. IQ at wide apertures on the A7 normally is not good. So the slow 4/21 Skopar is practical. Today I shall pocket the NEX-6 and the A7 to try out the Elmarit 2,8/28 ASPH on both. So, maybe I have something to show in the afternoon ...
