Has anyone compared the rendering of these two lenses and, if so, can you post photos especially with film? Thanks!
My Summicron C takes Series 5.5 filters. But i have an adapter to use the regular Leitz E39....& just scored a yellow series 5.5 for 5 £ (albeit with a postal charge of 20£)....I have the 35mm Summicron v3, sold the Summicron-C and replaced it with a 40/2.8 Heliar in LTM mount because I like the focal length a lot and can use it with my screw mount cameras. Before the Summicron-C I also had the CLE version of the Minolta 40/2.0. I started a thread about that lens somewhere here at RFF. About rendering, the 40/2.8 Heliar has the most modern character, followed by the CLE version of the Minolta 40/2.0. The Summicron-C is somewhat special with its good center sharpness but slightly soft corners. The CLE 40/2.0 takes easily to find E 40.5 filters while the Summicron-C takes almost impossible to find E39 filters with a different thread pitch. I bought some E34 to E37 and E34 to E40.5 step-up rings for the 40/2.8 Heliar that I also can use with my CV 28/2.8, which has a similar E34 filter size.

I just checked again, series 5.5 is ES39 but not E39. Both are 39mm diameter but ES39 (series 5.5) is 39mm x 0.75mm while the common E39 is 39mm x 0.5 mm. That's why I wrote "E39 filters with a different thread pitch".Series 5.5 is a Leica invention. The filters are 35.9mm in diameter.
There is a Leica Series 5.5 to 39mm adapter. It is like an 11251 with a 39mm thread at the front. It is almost impossible to find. Copies, fortunately, are not hard to find, but they tend to be in grippy aluminium not slick brass.
40mm Summicron C and 90mm Elmar C.... originally used Series 5.5 (non-threaded) drop-in filters that fit behind the screw-in rubber lenshoods.I just checked again, series 5.5 is ES39 but not E39.

Ah, my bad..... though i responded because i had used/owned both 40mm lenses (& at one time the CLE with its lens though i don't recall its superiority)....though the 1st version of the Rokkor 40 is optically identical to the Summicron C, and produced for the Leica (or Leitz/Minolta) CL. There were apparently 20,000 produced. The CLE version was issued in 1980. It wasn't clear that the OP was referring specifically to the latter version....even so, despite the newer coatings...it is still the German-designed lens.Wasn‘t the thread actually about the Rokkor, not the Summicron? Because there are differences: The later M Rokkor has multi coating and a 40,5mm filter thread. An excellent lens!
