Malabito Posted July 22, 2017 Share #62 Posted July 22, 2017 Here is one review https://blog.mingthein.com/2012/05/25/leica-50-2-apo-asph/ Another http://www.imx.nl/photo/leica/lenses/styled-4/ What kind of review has only words and no images? This is suppose to be photogrphay, not math..... (referring to the second link). Link to post Share on other sites More sharing options...

Malabito Posted July 22, 2017 Share #64 Posted July 22, 2017 It's Erwin Puts. His words are worth a thousands picture. No words are worth a thousand pictures, perhaps for those who don’t shoot it’s actually the other way around. A picture should be worth a thousand words.. Sorry but if I am to buy a lens I buy it by the images it produces, words and charts are just a complement. That’s why I buy lenses, to shoot, not measure sharpness and field curvature:) Maybe I should look at his writings like essays, but not related to action of doing pictures Link to post Share on other sites More sharing options...
james.liam Posted July 22, 2017 Share #65 Posted July 22, 2017 That's why you should rely on several sources, not one. Messr. Puts' technical analysis should help you understand the images you see posted by others. Link to post Share on other sites More sharing options...

Puts' technical analysis should help you understand the images you see posted by others. After further googling, (since I never heard of him) I realized it’s like a taboo topic talking about him within Leica lovers. Some dislike him other kind of follow his writings like they were pictures. Anyways it’s seems to be very controversy topic, I will drop it. Link to post Share on other sites More sharing options...
james.liam Posted July 22, 2017 Share #67 Posted July 22, 2017 Advertisement (gone after registration) It's not taboo. There are many, even here, who are critical of him. His old site had images with the commentary but he changed the format to straight text. He's a respected expert and author of many notable books on Leica. Take his words for what they are and come to your own conclusions. Link to post Share on other sites More sharing options...
lct Posted July 22, 2017 Share #68 Posted July 22, 2017 You're right, never believe words, too much web parroting here and elsewhere. Now never believe images either, too much p'shopping here and elsewhere . Just kidding but you are welcome to criticize self appointed gurus here. Puts has never understood anything in digital photography i believe but i'm not patient enough to read all his stuff so take what i say with a ton of salt .

philipus Posted July 24, 2017 Share #76 Posted July 24, 2017 I remember saying it when the 50 APO was released but lct's comparison shows it so clearly: by releasing the 50 APO (of which I do hope Leica will sell a lot) Leica made the 50 Summilux Asph the best 50mm lens in its line-up. Last time i did comparos between M 50/2 apo and M 50/1.4 asph i could hardly tell a difference at f/4 to be honest. See a couple of test pics at f/2 and f/2.8 below. - 50/1.4 asph, f/2.0: http://tinyurl.com/yazz846v - 50/2 apo, f/2.0: http://tinyurl.com/ybofwxdw - 50/1.4 asph, f/2.8: http://tinyurl.com/lekoloq - 50/2 apo, f/2.8: http://tinyurl.com/n6dyqd4 (M240, tripod, self timer, focus on "IX" with EVF and 10x magnification, 11 MB files) Link to post Share on other sites More sharing options...
lct Posted July 24, 2017 Share #77 Posted July 24, 2017 Hehe or the best 50 with so so field curvature and so so bokeh at f/2.8, which my pics do show as well Link to post Share on other sites More sharing options...
MarkP Posted July 24, 2017 Share #78 Posted July 24, 2017 Comparison of 2.0/50 APO-Summicron, 1.4/50 Summilux ASPH, and 2.8/50 Elmar-M They're all fabulous but some are more fabulous than others ;-) https://www.l-camera-forum.com/topic/246073-add-elmar-m-50-or-rigid-summicron-to-summilux-50-asph/ Posts 6, 7, 8, 10, 11 Link to post Share on other sites More sharing options...
cliveruss Posted July 27, 2017 Share #79 Posted July 27, 2017 50mm Leica lenses have accumulated on my shelf over the years - Elmar, Summitar, Summiluxes, Noctilux and several versions of Summicrons. I made a “family” photo, but it’s on a computer that is now in storage for a few months. The older lenses became slightly internally fogged over the years so mine have all been cleaned and are now crystal clear so that they project good contrasty images. I always use a lens shade. I recently set up a tripod and made images with all of the lenses at full aperture and all stops down to f/8, using an M9, focusing first at infinity, then at about ten feet. They are all very good lenses and made excellent images - even the early lenses. I viewed the enlarged image files on a computer screen. There is incremental improvement from the Summitar era lenses to the late Summicrons. The Summicrons were often considered to be the best 50mm lenses available at the time they were made, but I never particularly liked any of them. They are sharp, but the out of focus areas seemed edgy. I slightly preferred the Summiluxes (early and late). The Apo-Summicron 50mm is not an easy lens to borrow. It is also expensive to buy. A member of this community helped my curiosity by sending me details of an image I requested, showing and image focused at ten feet and including a distant horizon, at ƒ/2 and ƒ/5.6. The image details encouraged me to buy an Apo Summicron 50mm. I immediately noticed the improved image quality - sharp and smooth in both digital images and on film. It is the lens that I always wished for. Both the image quality and the physical manufacture of the lens are just right for my taste. It is the best 50mm lens I have ever used. In large format, I found a similar jump to "perfection", for my taste, when I bought the Rodenstock Apo Sironar-S lenses. They are noticeably better than anything I had ever used before (Protar, Dagor, Plasmat, Symmar, Apo-Lanthar, Tessar). The modern Cooke XVa lens gives similar fabulous image quality on 8x10 format. Will I now sell all my redundant 50mm lenses? Of course not. Do you think I am crazy! Link to post Share on other sites More sharing options...
Jon Warwick Posted July 27, 2017 Author Share #80 Posted July 27, 2017 I immediately noticed the improved image quality - sharp and smooth in both digital images and on film.

In large format, I found a similar jump to "perfection", for my taste, when I bought the Rodenstock Apo Sironar-S lenses. A very nice summary. It ties in my my observations as someone who recently got a 50 APO. It's a glorious mix of high sharpness but with smoothness at the same time. Really no "digital harshness" at all on the M240 despite the 50 APO's very high resolution. But more than anything, the best attribute for me of the 50mm APO is its 3D depth, which I find very noticeable (I look at images now from my Summicron v5 and immediately think they look "flat" and lifeless), supposedly due to the 50mm APO's sharp contrast roll off. I can also sympathise with your comments about the Rodenstock 4x5 lens, albeit in my case it's the other large format "gem" (the 110mm super symmar xl)!
