sergiofigliolia Posted April 23, 2015 Share #1 Posted April 23, 2015 Advertisement (gone after registration) Hi all, I am looking to buy a 35 summilux preasph to mount on both my M7 and M9. The issue is with M9 where there is the risk it can't focus to infinity unless modified by Leica. I know something about this is written at http://www.l-camera-forum.com/leica-wiki.en/index.php/35mm_f/1.4_Summilux_II What is your experience? I have asked Leica customer service how much would it cost (I am based in Italy). Is there a way to find out if it mounts by eye inspection? Link to post Share on other sites More sharing options...

menos I M6 Posted April 24, 2015 Share #2 Posted April 24, 2015 Only some 35 Summilux preASPH samples will need to be modified. The rear element shield will collide with the digital Leica's internal light baffling when the lens is focussed towards infinity. NEVER ATTACH AN UNKNOWN 35/1.4 pre ASPH TO A DIGITAL M WITH FOCUS SET TO INFINITY. Focus the lens to it's close focus distance before attaching to the camera, then carefully focus towards infinity - if there is no resistance, the lens is fine to use. The modification, if needed, is rather simple and any competent camera repair tech can do it. It involves removing the lens mount, removing the focussing helicoid, removing the rear element shield (fixed by a small screw to the optical cell), shaving the rear element shield to proper dimension, repainting bare metal of the shield with anti reflective paint, reassembling and testing. I would not send it to Leica if no other more serious work needs to be done. Link to post Share on other sites More sharing options...
rickp13 Posted April 24, 2015 Share #3 Posted April 24, 2015 IF you need to have the lens modified (my 2 didn't need any modification), then you may want to have the lens coded at the same time, so your M9 will recognize it. mine were done at kameratechnik in the netherlands. greetings rick Link to post Share on other sites More sharing options...
friedeye Posted April 24, 2015 Share #4 Posted April 24, 2015 Yikes. I had no idea, and have been using my Pre-asph lux on my M9 with impunity (and considerable joy). Guess I got lucky. It's a lovely lens with great character, albeit barrel distortion that's easily corrected in Lightroom. I particularly like the way older glass takes the clinical edge off digital cameras. Enjoy your lux - it's a classic. -- Jim Link to post Share on other sites More sharing options...
Duane Pandorf Posted April 24, 2015 Share #5 Posted April 24, 2015 My pre-ASPH focuses just fine at finity. Link to post Share on other sites More sharing options...
sender Posted April 25, 2015 Share #6 Posted April 25, 2015 I was worried about that too when I started using an M9, but my pre-ASPH worked fine. I carefully tried focusing to infinity at first, and there was no change in resistance. I use it all the time. Link to post Share on other sites More sharing options...
