tatetate Posted October 25, 2016 Share #1 Â Posted October 25, 2016 Advertisement (gone after registration) Greetings everyone, Â I shoot plenty of Film on my M setup and now i would like to add 35mm Summilux to my setup. I know there is alot of fuss about Focus shift etc on Asph version. Â Has anyone got examples or can someone share how bad is it? I wonder if its going to be a problem on in film? Â Thanks in advance T Link to post Share on other sites More sharing options...
Advertisement Posted October 25, 2016 Posted October 25, 2016 Hi tatetate, Take a look here 35mm Summilux Asph or Summilux FLE on FILM. I'm sure you'll find what you were looking for!
spydrxx Posted October 26, 2016 Share #2 Â Posted October 26, 2016 I had one but sold it for the Cron. It never was an issue for me on film. Link to post Share on other sites More sharing options...
happymac Posted October 26, 2016 Share #3 Â Posted October 26, 2016 I've owned the ASPH. for 20 years and in practice I've never seen focus shift. Neither on film nor digital. Link to post Share on other sites More sharing options...
FrozenInTime Posted October 26, 2016 Share #4 Â Posted October 26, 2016 I've been using the 35/1.4 ASPH for almost twenty years ( has it really been that long ! ) on film and never noticed any focus shift. Only when I added a M(9) Monochrom did I see the effect at say 2m distance and f/2 .. f/2.8 ; Â I guess on film I was full open indoors or f/5.6 outside. I did not think upgrading to the newer FLE was worthwhile as I could work around the characteristics of the older lens. Link to post Share on other sites More sharing options...
tatetate Posted October 28, 2016 Author Share #5 Â Posted October 28, 2016 Thank you. I think soon i will be in a position to compare both at home/yard level and might be able to share the results but honestly to me it would only matter if i see severe shift wide open and again we are talking about 35mm wide focal length. Â Thanks again for the replies. Â T Link to post Share on other sites More sharing options...
happymac Posted October 28, 2016 Share #6  Posted October 28, 2016 Make sure that each lens is adjusted correctly. After switching from M6 to M9 my ASPH has to be adjusted to hit the spot on f/1.4. Link to post Share on other sites More sharing options...
tatetate Posted October 29, 2016 Author Share #7 Â Posted October 29, 2016 Advertisement (gone after registration) Do i have to send it out for adjustment? Link to post Share on other sites More sharing options...
happymac Posted October 29, 2016 Share #8 Â Posted October 29, 2016 I'm afraid, yes! Body and lens should be calibrated as stand alones, but actually they work perfect if paired. That's why Leica recommends to send in both: Body and lenses. I've never understood, why two bodys can be different, but I guess it's due to the very, very small tolerances. Film may cover this phenomenon. Â Tom Link to post Share on other sites More sharing options...

Â Tom Actually they like to have both to be sure both are adjusted properly.Tolerance matching only makes sense for very critical lenses - Noctilux, Summilux 75, Summicron 90 APOASPH, Telyt 135 APO.
