pziddy Posted December 24, 2020 Share #1  Posted December 24, 2020 (edited) Advertisement (gone after registration) Lenses tested on M10-R. Lens corrections only. Otherwise SOOC. I feel like something is wrong with the Sonnar (the purple fringing is everywhere). The Voigtlander looks sharper in the center than the Summilux. That surprised me. The summilux doesn't suffer from astigmatism the same way the Voigtlander and Sonnar do. Anyone else have a Sonnar that can confirm the fringing here is normal?  Zeiss C-Sonnar T* 50MM F1.5 ZM Welcome, dear visitor!

Advertisement Posted December 24, 2020 Posted December 24, 2020 Hi pziddy, Take a look here Summilux/nokton 1.5/sonnar 1.5 test shots. I'm sure you'll find what you were looking for!
wda Posted December 24, 2020 Share #2  Posted December 24, 2020 Pziddy, welcome. I regret I cannot help you with experience of your two non-Leica lenses, but I do question your choice of test subject. What was the justification for your choice? 2 Link to post Share on other sites More sharing options...
jaapv Posted December 24, 2020 Share #3 Â Posted December 24, 2020 The Sonnar shows longitudinal chromatic aberration.It could be normal, but it does seem to be a bit excessive. I agree with WDA about the test shots. 1 Link to post Share on other sites More sharing options...
UliWer Posted December 24, 2020 Share #4  Posted December 24, 2020 The „test“ subject - even if it is not the habitual brickwall or „bokeh“ situation - is quite relavatory. It not only shows the chromatical aberrations of the Sonnar but also some very strong examples of coma if you look for the lights at the lower left parts of the second series. Though you cannot expect a lens design which is now almost 80 years old and was not made better when it was simplified for the „modern“ version of the Sonnar to equal the results of lenses with aspherical elements Link to post Share on other sites More sharing options...
Charles Morgan Posted December 24, 2020 Share #5  Posted December 24, 2020 The Sonnar is a character lens, most of which comes from chromatic aberrations. Not being one to do night shots with the one I had, I suspect that is displaying the normal amount. This was I think the only time I used mine at f1.5 to take a photo of point light - theres a lot of fringing even on film. To be honest, it's not a lens to use if you are worried about aberrations. I didn't sell mine for that reason, but for too much contrast. But I have a Jupiter 3 soon to be sent off for refurbishing by Skyllaney, and that should be exactly what my doctor ordered. Welcome, dear visitor!

farnz Posted December 24, 2020 Share #6  Posted December 24, 2020 Sensor bloom from the spectral highlights?  It only occurs on those spectral highlights that are very bright and overblown.  Why isn't it as visible in the other lenses?  At a guess because the lenses have different transmissibility and the transmissibility of the Sonnar might be the highest because has the fewest lens elements that attenuate the light.  Just a theory.

lct Posted December 24, 2020 Share #7  Posted December 24, 2020 Advertisement (gone after registration) Never noticed disturbing CA out of my Sonnar 50/1.5 so far, at least compared to my worse Summilux 50/1.4 pre-asph from this viewpoint. What i see in the Zeiss pic above looks more like coma but it's hard to tell w/o the raw file. Welcome, dear visitor!

BrianS Posted December 24, 2020 Share #8  Posted December 24, 2020 (edited) On my Leica M9, Most of the character of the C-Sonnar and other Sonnar formula lenses comes from the spherical aberration inherent in the design.

As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Another night shot. The Blue Lights in both your shots and mine seem to be casting more veiling flare, possibly as the lens coatings are not as effective in this portion of the spectrum. I don't think it is CA, as the white incandescent lights would show the effect. I've never seen any of my Sonnar formula lenses show CA to the degree that would be required to explain your images. . Edited December 24, 2020 by BrianS 1 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!
