Michael Markey Posted July 13, 2020 Share #24  Posted July 13, 2020 Just bought a CL and recently bought the 23. I use it together with M lenses . Very pleased with the 23 lens .... the AF is so snappy . Based on the 23 I`m looking to build up a three lens set .   1 Link to post Share on other sites More sharing options...
cj3209 Posted July 13, 2020 Share #25 Â Posted July 13, 2020 The 23 TL is so compact; I grab it over the 35 when I'm shooting outdoors... Link to post Share on other sites More sharing options...
bcorton Posted July 14, 2020 Share #26  Posted July 14, 2020 Here is another evaluation.  Nothing shows up a lens's aberrations better than astrophotography.  Here one commonly uses a lens at maximum aperture or near it, and a poorly-corrected lens will quickly reveal its defects—flare, coma, CA, etc.—on those pristine little star points. The 23mm Summicron is one of my favorite lenses for star-scapes.  There is a little bit of coma near the field edge, but it is minimal and counts as well-controlled, indeed. Here is an example of an unguided shot of the Northern Milky Way.  The green cast in the lower part of the image is from a photochemical reaction in the upper atmosphere.  Note the Andromeda galaxy in the lower right hand corner.  A keen eye—or I should say, an eye that knows what its looking for—will spot one of its companions just above.  (TL2, 23mm Summicron, f/2, 10 sec., ISO 3200.) This is quite a fine lens in my opinion.  Welcome, dear visitor!

stephengv Posted July 18, 2020 Author Share #31 Â Posted July 18, 2020 How is the bokeh of the 23 Summicron? Link to post Share on other sites More sharing options...
stephengv Posted July 26, 2020 Author Share #32  Posted July 26, 2020 Just a follow up, how does the 23 compares with the 18? Link to post Share on other sites More sharing options...
jaapv Posted August 1, 2020 Share #33  Posted August 1, 2020 The 23 is supposed to be the better lens which is logical, given that the compromises of the design of the 18 are slanted towards compactness with acceptable quality. Link to post Share on other sites More sharing options...
graphlex Posted August 4, 2020 Share #34  Posted August 4, 2020 (edited) The 18 is really pretty good. Edited August 4, 2020 by graphlex Correction Link to post Share on other sites More sharing options...
