AceVentura1986 Posted January 7, 2019 Share #41 Posted January 7, 2019 Advertisement (gone after registration) I’ve got the CV 35m f/1.4. It is a great little lens provided you know and can live with its limitations. As mentioned above, I generally also use it as an f/2 lens and will use f/1.4 only sparingly because of the softness encountered at this aperture. At f/2 and above it is a very competent lens.

Advertisement Posted January 7, 2019 Posted January 7, 2019 Hi AceVentura1986, Take a look here 40mm Leica Summicron as a compact lens?. I'm sure you'll find what you were looking for!
lct Posted January 7, 2019 Share #42 Posted January 7, 2019 My CV 35/1.4 "SC" has so much flare and focus shift that i don't use it on rangefinders anymore. Works better on mirrorless cameras but flare it so much an issue that i prefer my M 35/1.4 v2 let alone 35/1.4 FLE from this standpoint. YMMV.

sblutter Posted February 4, 2019 Share #43 Posted February 4, 2019 the 40's are great (I prefer the Rokkor due to 39mm filter size) - but also consider the Elmar-M 50. Really sharp Quote Link to post Share on other sites More sharing options...

Really sharp I wonder which Rokkor takes E39 filter. Mine M-Rokkor 2/40mm has E40.5 and Older Rokkor 2/40 Series 5.5 filters same as Summicron-C 40mm. They are all great anyway ☺️.

lct Posted February 5, 2019 Share #45 Posted February 5, 2019 Both Rokkor 40/2 for Minolta CL and CLE have E40.5 filters as i understand it. Quote Link to post Share on other sites More sharing options...

The 5.5 filter is actually 39 x 0.75mm and Heliopan still make that size (or did, hard to come by). I have them on my Summicron-C 40 and my Elmarit-C 40.

For outdoors/hiking, this is my preferred lens (along with 90mm Macro-elmar m). Quote Link to post Share on other sites More sharing options...
stephengv Posted July 10, 2019 Author Share #50 Posted July 10, 2019 Thank you for the replies. I just ordered a converter/adopter on Ebay to adopt a 39mm UV Filter. Anyone tried the said adopter? Quote Link to post Share on other sites More sharing options...

Edit: Series 5.5 filters are also used in a filter drawer with the Apo-Telyt-R 280/4. LCT, You picked my curiosity with the Series 5.5 . I remember that at one time, I wanted some colored 5.5 filters for my Apo-Telyt-R 4/280, and never found one. So I had a look at this reference site for Series filters but i've found errors (or maybe another truth ) in the dimension of Series 5.5 filter as 40.5mm large, retaining ring 43.7mm , then I measured the 5.5 neutral only one that I have in filter drawer of the Apo-Telyt-R 4/280, it's about 36mm. So many mysteries (or truths ...) when we talk about Series filters. Quote Link to post Share on other sites More sharing options...
lct Posted July 10, 2019 Share #54 Posted July 10, 2019 (edited) Yes i would say about 36mm as well since Series 5.5 filters can be dropped below the rubber hood of C-40/2 and C-90/4 which are both ø 39mm lenses. I've never measured mine though. BTW colored Series 5.5 filters can be found on e**y. Edited July 10, 2019 by lct Quote Link to post Share on other sites More sharing options...

Whilst the Leica C lens are, indeed 39mm, they are 39 x 0.75 as opposed to the normal E39 which is 39 x 0.50. trying to fit a normal E39 filter will usual result in damaged thread.

Learnt this 30+ years ago . So when using regular 39mm filters, better refrain from tighten them on 40/2 and 90/4 C lenses. But Series 5.5 are Series 5.5. No filter thread on those filters .

I was simply pointing out the different thread pitch and warning against using E39 when the correct filter is available from Heliopan. Yes I know that 5.5 have no thread but the lens hood/adaptors for them do. Quote Link to post Share on other sites More sharing options...
a.noctilux Posted July 10, 2019 Share #58 Posted July 10, 2019 We can say here that Series 5.5 filter : - has to be used with retaining ring or dedicated hood (39x0.75) on Summicron-C 40mm or Elmar-C 90mm - on "C" lenses if we use another retaining ring, hood or adapter it must be 39mm size x pitch 0.75mm - on "C" lenses we can use 39mm x 1mm filter (from Nikon) or E39 filter (39mm x 0.5mm pitch), we must not screw too far - in the market, adapter E39 (39x0.5)F to 39x0.75 M exists so the best solution can be here to use more common E39 filters Quote Link to post Share on other sites More sharing options...

If you don't then seek out the Heliopan filter or the correct adaptor as per your last line. Quote Link to post Share on other sites More sharing options...
a.noctilux Posted July 10, 2019 Share #60 Posted July 10, 2019 The problem WAS not with "C" lenses that I don't have, I use the Minolta 2/40 M-Rokkor "same lens" with E40.5 common filters, but lct mentioned Series 5.5 filter for the "best Telyt-R lens" ... Apo-Telyt-R 4/280 that Leitz/Leica had the idea to put a "5.5 Series filter holder" (the only one in this case) 1 Quote Link to post Share on other sites More sharing options...
