Guest JoanMarianne Posted November 22, 2009 Share #1 Posted November 22, 2009 Advertisement (gone after registration) I would be interested to read opinions and descriptions of the performance of the Hektor and Summaron 28mm lenses. I hope to use one on my M4-P, along with my uncoated 35mm and 50mm Elmars. Link to post Share on other sites More sharing options...

Guest liesevolvo Posted November 22, 2009 Share #2 Posted November 22, 2009 Why not try the wonderful Voigtlaender Color-Skopar 3.5/28, in my humble opinion the best lens, Cosina has ever made.... Lenn from Cologne/Germany Link to post Share on other sites More sharing options...

peter_n Posted November 22, 2009 Share #4 Posted November 22, 2009 JoanMarianne I don't use either lens as the above posters but I'd just like to paraphrase the Hove Leica Pocket book (7th ed.) on these two lenses (pp. 97 & 98) in case you've not seen the descriptions there. Hector 28mm/f6.3 Stopped down to f8, it delivers quite fine performance, even in the non-coated version when used in clear daylight situations. There is significant vignetting that is still visible at f8 and smaller. Distortion is not visible at all. Medium contrast at the (modest) maximum aperture with good reproduction of the subject outlines and pleasing central definition of the finer details. The zones next to the center are quite soft, but improve when approaching the corners. Best aperture is f11. Production Period: 1935 - 1953. Summaron 28mm/f5.6 Offers high performance even considering the modest aperture but is regrettably scarce. Vignetting is quite visible with 2.5 stops but there is no distortion. High contrast at the maximum aperture with crisp definition of very fine detail over the larger part of the picture area. The corners are soft but still usable. Astigmatism is very well controlled, optimum aperture is f8 - f11. Smaller apertures have less contrast but coverage is extended into the corners. Production Period: 1955 - 1963. Although coated/uncoated is not in the description of either lens, from the descriptions it looks like if you want an uncoated lens the Hektor is the one to go for. Good luck in your search!

luigi bertolotti Posted November 22, 2009 Share #5 Posted November 22, 2009 I have both, and always preferred the Summaron, which at 8-11 is appreciable even to today' standard when used at 8-11. The Hektor, designed in times when color was an oddity, is really a bit poor on contrast, and it retains the Elmar-style f/adjustement ring around the front lens, which is pleasantly oldstyle, but less easy to manage than the "modern" ring of the Summaron (to be sincere, f adjustement is not so important... keep them at 8-12,5 and that's good... ). Both are incredibly compact... stored in their fine bakelite box are the most pocketable lenses one can imagine; finding a proper hood isn't easy... they are costly collectibles.

luigi bertolotti Posted November 22, 2009 Share #7 Posted November 22, 2009 Advertisement (gone after registration) Sorry for the insistence... but I love so much old lenses... ; inspite of the "film forum" I attach two pics made tonight with M8 (so, borders cropped... the vignetting is gone away...); a trivial interior scene with intrinsic low contrast... a test not so "optimized"... M8 set at 640 ASA and JPG fine to make quick posts. First, Hektor, then Summaron, both around f11, focused on the Elmarit 24 next to the bottle. 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! I never tried my Hektor on M8... and, as expected, contrast is lower (images unpostprocessed at all) But the ethernal test for digitals, i.e. the "100% crop" shows that the Hektor is not so bad in term of sharpness (first Hektor, then Summaron): So... up to you... surely for b&w Hektor can be a respectable lens (btw... my item dates to 1935...)

Guest JoanMarianne Posted November 22, 2009 Share #8 Posted November 22, 2009 Thank you gentlemen, that is most helpful. The Summaron looks the better prospect but I'll go for whichever becomes available first. The uncoated types turn in unique performances, particularly in full sunlight.
