I shot mostly at minum focus distance, or 1m roughly and i could say it’s safe i noticed focus shifts slightly when goes beyond 2m and infinity but i might b wrong since i didnt test it thoroughly 1 Link to post Share on other sites More sharing options...

Daniel C.1975 Posted January 31, 2020 Share #124 Posted January 31, 2020 Great lens and really nice photo. I also understand why you‘ve focussed where you‘ve focussed. However, in a classical portrait the eyes are the part which are expected to be in focus - just kidding and no offense mend 4 Link to post Share on other sites More sharing options...

adan Posted October 21, 2020 Share #126 Posted October 21, 2020 Just ran across a used Voigtlander 75mm Nokton f/1.5 - some preliminary observations: 1. This lens has pretty phenomenal resolution - at f/1.5 - at infinity or thereabouts - in the center of the image. The crop below is from an M10 (no R) image. The buildings are about 1km away, the lower foreground at about 120m. A little wobbliness in some of the window mullions is likely atmospheric refraction (heat waves in the foreground - big asphalt parking lot). Full-frame image below that, for reference. I've used a lot of f/1.4-ish lenses - don't recall detail this fine from any of them wide-open. 75 Summilux-M, 50 Summilux-M pre-ASPH and ASPH, Contax/Kyocera/Zeiss 50mm and 85mm f/1.4 Planars, 35 Summilux-M pre-ASPH and ASPH v.1 It is a relatively low-contrast resolution (see "Transamerica" logo - wouldn't score high in MTF), and the overall image contrast is also moderate (see full frame) - at F/1.5 - although possibly because to shoot f/1.5 in hazy sunlight, I was overexposing about 2 stops and had to "pull" the image in post-processing. The image also muddies up more approaching the edges (spherical and chromatic aberrations - see small crop of TIAA antennas) - but I don't see any sign of curvature of field at infinity. A tiny bit of red fringing (see balconies right-center) I'll be the first to admit that infinity performance at f/1.5 is not exactly what such lenses are mostly used for - unless one shoots a lot of night cityscapes. Still, it is noteworthy. 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! 2. This is not really a direct substitute for the 75 Summilux. Just too many little places Cosina and Dr. Mandler chose to take different paths - color rendering, global contrast, aberration trade-offs and so on. They "draw" somewhat differently. 3. Equally unlike the Summilux, the Nokton is phenomenally light - 338 grams without caps or hood. That is 90/75 Summarit-M f/2.5 territory. 4. The handling otherwise is very "laboratory-grade" - the aperture ring and focus ring are like turning the vernier dials on a high-end microscope, or Sinar rail focus controls - greasy-smooth and well-damped. 5. As with the 75mm f/1.8 Heliar, the Nokton is really about a 73mm lens - captures a slightly wider area than my 75 Summicron. I'll be back with some other notes as I get time to test this lens further. Only had it two days. 8 2 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members! 2. This is not really a direct substitute for the 75 Summilux.

adan Posted October 28, 2020 Share #130 Posted October 28, 2020 Finally, the last test I'm going to show (unless someone requests something). Close-up behavior at f/1.5 Taken at ~1m, M10 The detail crop shows: - quite good resolution, at a moderate contrast (the dirty glass, and a reflection, may be reducing contrast even more). Note the readable letters and currency engravings. - one characteristic that is reminiscent of the 75 Summilux - spherical aberration extends the apparent depth of field in this range. Note how the circled "(1)" on the currency in the background is not as blurry as one might expect at f/1.5. The SA "layers" sharp and unsharp images from various distances (within reason) to produce a kind of focus-stacking. The overall shape is legible, and the fall-off in sharpness is smooth. I have found this to be a useful feature using rangefinders with fast long lenses (Mandler's 1980-era 90 Summicron-M and 75 Summilux-M) - it gives a little extra leeway to misfocus and still get "readable" details. it is also what some call "soft sharpness." I'm feeling as though I really like this lens - it combines pluses from a variety of 75s, (light-weight, large-aperture, good resolution in the center without being clinical, close-framing). But I look forward to a time when I can try it in other appropriate "fast 75" situations Covid makes difficult: extensive people close-ups/portraits, and also concert/stage work. I don't expect many opportunities for those for quite a while. Welcome, dear visitor!

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! Thank you for these great pictures showing the "Leica Glow". It is back on M10 via a non-Leica lens! It is good to know that modern M10 sensor resolution and other factors can produce this old aesthetic. QUESTION: Adan, can you get the glow with less than 24meg resolution of the M10?

adan Posted October 30, 2020 Share #132 Posted October 30, 2020 Oh, I expect Leica Glow - if present at all - would show even in 1 or 2 megapixel images. After all, most of the pictures we see here on the Forum have been downsized to about that resolution. . 1 Link to post Share on other sites More sharing options...

Herford in Germany It is called "Fürstenaudenkmal" Copy paste in deepl: Anton Fürstenau holds his right hand dismissively against the Sparrenburg in Bielefeld and thus against the Count of Ravensburg, who was close to the Brandenburgers. With a great deal of negotiating skill and money, Fürstenau was able to prevent the capture and devastation of the city of Herford during the Thirty Years' War. With his left hand, he points to a document guaranteeing the city of Herford imperial freedom. The head, which is split several times, symbolizes the stages of his life, from the young dynamic man to the old, worn-out one. 1 Link to post Share on other sites More sharing options...

Thanks y'all for the pictures you contributed in this thread! I am also in the market for a fast 75 prime and so far I am leaning towards the Nokton as the overall rendering / character, price and weight is more my cup of tea than the alternatives. What I learned so far from your photographs is that the Nokton is pretty sharp / contrasty already wide open with a smooth transition zone towards the out of focus areas, but with objects further away (e.g. 5 m / 15 ft) the out of focus areas become more defined (like in the example shown above). So... the closer the subject, the smoother the bokeh - is that, what you observe as well? ...and by the way... more pictures, please! 😍 1 Link to post Share on other sites More sharing options...
hdmesa Posted March 18, 2021 Share #139 Posted March 18, 2021 What a great lens. Mine arrived today. This lens is incredibly sharp even at minimum focus distance. It does help to move back slightly so that the point of focus is a couple of centimeters behind minimum distance – that way if I sway back and forth just a little, I can still get something in focus (on objects that recede, not ones parallel to the sensor). I'm also not seeing the reported "glow" wide open at MFD with this lens unless I miss perfect focus or have motion blur from too low of a shutter speed. Maybe I haven't hit the right lighting or pushed the focus point right up to MFD to see the glow. Anyway, I'm finding that for me, 1/500 sec. is minimum for this lens on the M10-R, and 1/1000 or higher is best. Wide open close to MFD: Welcome, dear visitor!
