Cowz Posted August 12, 2021 Share #1 Posted August 12, 2021 (edited) Advertisement (gone after registration) So I wanted to see how the lenses I have work for sharpness, accuracy, micro contrast and bokeh at a reasonable portrait distance. Shooting a statue at about 2 meters seemed to be a good representative of what I wanted while maintaining consistency in spacing and focus. It was a cool, sunny day and I trie to get both shaded and sunlight parts of the subject. The SL was on a tripod in A Priority with a 2sec countdown timer. I did not use any in camera corrections except for what the camera detected (the Sigma lens and the only six bit coded 75mm f2.5 Summarit). I shot each lens wide open, then at the common f2.8 (135 has two images only) and then at f5.6. Only corrections applied was a SL Profile by David Farkas of Red Dot Forum. Each triplet was then exported at 15% to fit the forum max size. I tested the following SIGMA 35mm f1.4 DG HSM Art TTArtisan 35mm f1.4 TTArtisan 50mm f0.95 Canon 50mm f1.4 LTM V1 (1957 vintage) Leica 50mm f2 Summicron (1986? not six bit coded) 7Artisan 75mm 1.25 Leica 75mm f2.5 Summarit (6 bit coded) Leica 90mm f2 Summicron (pre APO) 135mm f2.8 Elmarit (goggled) Edited August 12, 2021 by Cowz add text Link to post Share on other sites More sharing options...

Cowz Posted August 12, 2021 Author Share #13 Posted August 12, 2021 So what are my findings.... 1. All the lenses work amazingly well despite the difference in make and manufacture 2. The TTArtisan 35mm is incredibly sharp (also has the biggest fie size, I still need to ascertain why) 3. The two 75mm had marked difference angle of view (effective focal length) 4. The three 50mm had very similar angles of view. 5. I did not use any camera profiles that were not automatically assigned, which led primarily to a difference in vignetting 6. Age of lens does not influence image quality that much. 7. Biggest difference is out of focus areas and fall off. Obviously the mid tele lenses have better OOF but to my eye, I like the 75mm by 7 Artisans the most Please feel free to add any findings 1 Link to post Share on other sites More sharing options...
p-arrow Posted August 12, 2021 Share #14 Posted August 12, 2021 Thanks for doing this test! Pretty surprised by the vignetting on the Summicron 50. I'm guessing a lens profile would do away with that, but it's way more dramatic than I would have thought. I've been thinking about picking up a SL and Summicron 50 M mount combo in the near future. How would you say the lens performs on the SL, aside from the vignetting. Hard to get a good sense with the low-res photos. Link to post Share on other sites More sharing options...
Cowz Posted August 13, 2021 Author Share #15 Posted August 13, 2021 (edited) The Cron and SL work together amazingly. When the profile is dialled in, all distortion and vignetting disappear. Even then, it was mostly gone by f5.6 and clear by f8. I love my little 50, its an older v5 brass and chrome and solid like a chunk of, well brass and glass. It has amazing rendering ability. Funnily enough, the 75 Summarit is every bit as clear and sharp with great micro contrast, but 75 vs 50 may turn people off. I shoot a lot of outdoor portraits, so I love the 60/75/90 combo. The longer M glass is difficult to use on my M10P (without visoflex) and M9M but a breeze on the SL. I can almost focus as quick and accurate as an AF lens and I can ensure the correct focus point. I was pleasantly surprised at the 135, which was cheap, written of by many and ugly as sin, but for environmental portraiture, should make for some amazing bokeh. Side note, its funny to think my slowest lens is f2.8 🤣🤣🤣🤣🤣 Edited August 13, 2021 by Cowz wrong value Link to post Share on other sites More sharing options...
