JimKasson Posted December 18, 2013 Share #3781 Posted December 18, 2013 Advertisement (gone after registration) Jim, Zeiss NEX lenses are designed for APS-C size sensor 16 x 24mm. Precisely my point. Look how big they made the lens when the sensor was much smaller. Jim Link to post Share on other sites More sharing options...
Advertisement Posted December 18, 2013 Posted December 18, 2013 Hi JimKasson, Take a look here The Sony A7 thread [Merged]. I'm sure you'll find what you were looking for!
JimKasson Posted December 18, 2013 Share #3782 Posted December 18, 2013 Find your dimension for M lenses with adapter confusing tube is about 9-10mm and lens are about 40-50 mm flange to filter ring. My bad. I took a look at the ruler I used, and all the distances I quoted are in agate lines. 1 agate line [Adobe] = 1.8142857 millimeter. Sorry, Jim Link to post Share on other sites More sharing options...
k-hawinkler Posted December 18, 2013 Share #3783 Posted December 18, 2013 You're being very gracious K-H. I didn't read a request for artistic critique. Did I miss that?Of course it would be easy to obfuscate the technical merit of the test images you posted by using a different, subjective criteria. But what reason would any individual have for doing that... I definitely have the impression though that colors of the A7R are not as compromised by infrared contamination.

AlanG Posted December 18, 2013 Share #3784 Posted December 18, 2013 It appears in the Sony/Zeiss 24mm f/1.8 case, the lens designers sacrificed compactness in order to achieve better image quality, and decided not to build a small lens and to try to fix it up in firmware. Jim I don't know what choices the designers made. But if the lens barrel length has little to do with it. The Nex body is thinner than the Leica body. So that distance has to be made up in the lens barrel length... all other things about a lens design being equal. Add the Nex to M adapter to the M lens and measure again. And as mentioned the Nex lenses are for APS so that changes the design choice. E.g. a 24mm lens on a Nex can use a shorter version of the same design as a 36mm lens on FF. So it can be a much more moderate wide angle design. If you measure the total thickness (from the LCD to the front of the lens) of a Nex with the 24mm lens on it compared to a Leica M with a 24mm lens on it you will get a better idea. But you'd also have to consider if the different apertures of the lenses.affect things. Link to post Share on other sites More sharing options...

Rick Posted December 18, 2013 Share #3786 Posted December 18, 2013 Rick, your generalizations still focus on lens performance with lenses designed for M240. The A7R can deliver good (and of course better) performance in the edges, when you use lenses that do not have to make too many compromises for compactness. The FE 35/2.8 is still also a compromise - but on a very high level already. Corner performance is not only a matter of the camera, it is also a matter of lens selection. From the edge performance of a 50 APO Summicron I also expected more - but also when used on the M 240. The slightly better results when used on the M240 can also be caused by the internal correction of the M 240 firmware. I can not see an indication, that Lensrentals switched off internal correction. A more realistic comparison would be, when the internal compensation of the M 240 were disabled or when you compare e.g. the new Zeiss FE 1.8/55 on A7R with an APO Summicron on M 240 (which also would mean comparing a 3100 EUR combo with a 12200 EUR combo...). I am sure we will see that soon... Those complaing about poor results with most WA RF lenses should compare the cost of an A7® + WATE to a Leica M 240 body given you an excellent WA RF lens already for free... Ok, I understand the rationalizations. You don't need to sell me on them. I already sent the camera back. But, I get what you are saying: The A7R would be comparatively better if, you turned the internal correction off in the M240, and the M240 cost less and you didn't use WA lenses on the A7R, and if they were not Leica M lenses, and you used the only 2 system Sony lenses, and you didn't care about poor edge performance... Ok, I'll wait and see if the new Zeiss FE 55/1.8 can produce good corners? As a bench mark (and not necessarily a great one) let's wait and see if, the Sony A7R with all of its 36MP of goodness and the new Zeiss FE lens can resolve in the corners at least 860Lp/IH as the old M240 (24MP) + the old Summilux 50mm/1.4 does. Until then, I'll sit on the side lines and believe this camera has a somewhat serious edge design issue. Here is something else for you to read along with the Lens Rental article: Canon 5D Mk III vs. Sony A7 vs. LEICA M typ 240 Image Not a perfect comparison, but what is? And, again, this is a nice camera for what it does do. I get why for $2,400 it is pretty good especially for those that have a bunch of FF lenses to try on it.

My ACR has both a blue-yellow and a green-magenta slider, unlike, apparently, his… He states, "in the Leica." These are JPGs and I guess he is talking about making these changes in the camera. He is a god laugh as he takes a swipe at Sony and Leica in his conclusion/recommendation. It is interesting that he gets on all the hot topics to drive traffic to his site. But, the edge example are are what you should look at. Link to post Share on other sites More sharing options...

jlindstrom Posted December 19, 2013 Share #3799 Posted December 19, 2013 The real joke is KR getting quoted as a photography expert in national news papers. No, the funniest thing is that for years when a new camera has been out, KR has "reviwed" it and then forums go mental on bashing him. I've said previously and I'll say it again, the guy's articles are entertaining and on the other hand he should be applauded for finding his own niche and making money of it. At times he also produces nice photos, not necessarely about xmas lights though ;-) Also at time he has some valid points. His articles should be taken as personal opinions more than thorough reviews. If you bother to read between the lines and filter some crap, there are actually some valid points too. For example lots of historical data on Leica lenses. First chapter in reply to CaptZoom, rest a personal point of view to KR. //Juha Sent from my iPad using Tapatalk HD Link to post Share on other sites More sharing options...
