Jeffry Abt Posted July 18, 2014 Share #1 Posted July 18, 2014 Advertisement (gone after registration) Is the image quality comparable between the the APO 50mm Cron and the APO 75mm Cron? Did Leica make significant headway between the release of the APO 75 and APO 50? Link to post Share on other sites More sharing options...
Advertisement Posted July 18, 2014 Posted July 18, 2014 Hi Jeffry Abt, Take a look here APO lens 50mm & 75 mm. I'm sure you'll find what you were looking for!
Guest odeon Posted July 18, 2014 Share #2 Posted July 18, 2014 They are quite different. Technically, 50'APO-cron is the best of Leica. Link to post Share on other sites More sharing options...
Jeffry Abt Posted July 18, 2014 Author Share #3 Posted July 18, 2014 Does the 75 minimizes chromatic aberration as well as the 50? Does the 75 produce detail rendition as well 50? etc. What are the differences? Do y'all ( Pease pardon my Texanism) have any experience with both? I understand that the 50 is almost perfect ..... Is the 75 a mere distant 2nd to it? Link to post Share on other sites More sharing options...
pgk Posted July 18, 2014 Share #4 Posted July 18, 2014 ....Is the 75 a mere distant 2nd to it? I haven't tried the 50APO but the 75 is a fabulous lens. You would need to be very, very picky to want much better........ Link to post Share on other sites More sharing options...
algrove Posted July 18, 2014 Share #5 Posted July 18, 2014 Leica's definition of APO seems true in both cases just like with the APO 90/2. Leica takes the APO definition seriously. Link to post Share on other sites More sharing options...
Duane Pandorf Posted July 18, 2014 Share #6 Posted July 18, 2014 I've recently purchased the 75 APO. I'm very happy with the results but I know it will take some time to fully appreciate its qualities. In my short experience shooting Leica I think I can say all of their latest lenses are outstanding. If you're trying to decide between the two then I think it depends on what you're preferred focal length is. Link to post Share on other sites More sharing options...
paulsydaus Posted July 19, 2014 Share #7 Posted July 19, 2014 Advertisement (gone after registration) The 75 APO is one of their best lenses. Performance is outstanding. There is no better short telephoto lens (currently available) for 35mm photography. You would have to be a pixel peeping madman not to be impressed by it. Your question should be more towards what type of focal length you prefer... Standard or short telephoto. 75 is the better choice for portraits etc... According to the MTF charts, the 50 APO has 10% better contrast on super fine details like hairs. If that matters to you, then get the 50 APO. But the more photography you do the more you will realise how insignificant that is and you should be concerning yourself with other things like focal length, depth of field, and lighting...

Jeffry Abt Posted July 19, 2014 Author Share #8 Posted July 19, 2014 Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! This is my concern. The attached image (taken with a noct.f1) exhibited overwhelming chromatic aberration...was worthless in color. I would like to take such an image in color without having to stop down the lens to cut down on chromatic aberration. A 50mm or a 75mm would have done the job as to focal length. Sounds as if they are almost the same as to image quality and chromatic aberration as well. Sorry about dragging this question out. But, I just loathe 'chromatic aberration' and am thinking about an APO lens. Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!

pfhrased Posted July 19, 2014 Share #11 Posted July 19, 2014 the 50mm Summilux is also APO-corrected, if you wanted to look at a cheaper option than the APO 50mm f/2. It's still not nearly as cheap as the 75/2 APO though. Link to post Share on other sites More sharing options...

tobey bilek Posted July 19, 2014 Share #13 Posted July 19, 2014 75 APO is modeled after the 50 1.4 which is supposedly APO but not in the name. I have not noticed CA in either. The .95 is improved over the F1 Noct whose design dates to the 80`s , but with cosmetic changes. Link to post Share on other sites More sharing options...

I am relatively new to the Leica world and have never read that before. There are lots I do not know, But admit I am incredulous. Why would Leica keep such information secret?

I am relatively new to the Leica world and have never read that before. There are lots I do not know, But admit I am incredulous. Why would Leica keep such information secret? They really don't. You can probably find such info in a book or other publication by Erwin Puts, my guess. Link to post Share on other sites More sharing options...

I am relatively new to the Leica world and have never read that before. There are lots I do not know, But admit I am incredulous. Why would Leica keep such information secret? David Farkas spoke with Peter Karbe, and reported that Peter said the 50 Summilux ASPH had an APO element despite its not being advertised as APO. In a similar Shutterbug interview with Karbe, he states that the one element in the 50 Summilux ASPH costs more than all the other glass elements combined. However, having said that in these old interviews, I believe I've read that the 50 APO Summicron offers even better color correction, although I can't locate the source. This wouldn't be surprising given the advances in technology, and the many years in the evolution of the lens (reportedly over 16 years to come to market). The fact that both lenses are so small despite the optical quality and level of corrections, is what separates Leica from the competitors (for instance as compared to the Zeiss Distagon as Puts reports here.)

agencal Posted July 20, 2014 Share #17 Posted July 20, 2014 I jave both.All i can say is they are in different leagues.75mm is a great sharp lens corner to corner.50mm is also has this plus a unique abilty which i can describe shortly as clearance,definition and lifelike.If sharpness is number one one your list 75mm will give you that as 50mm but being lifelike belongs to few lenses in the world. I saw this at Voigtlander 125mm apo,coastal 60mm,zeiss otus and zeiss 135mm f2.Leica has this only at 50mm apo and 24mm elmar f3.8.(this is my opinion of course) Link to post Share on other sites More sharing options...

hoppyman Posted July 20, 2014 Share #19 Posted July 20, 2014 I've never shot more than a handful of frames with the new APO 50. I've shot a lot with the 75 though. I've never seen any problems in use against the light like your example, myself. stvm3137 photo - Geoff Hopkinson photos at pbase.com Dr Ted Grant, Canadian Master photographer photo - Geoff Hopkinson photos at pbase.com Link to post Share on other sites More sharing options...
