Aviator Posted January 7, 2011 Share #21 Posted January 7, 2011 Advertisement (gone after registration) A modified 40 Summicron will bring the 35 frameline on every Leica with 35 frame lines. On the CL it will bring the correct 40mm frame line. The obly backlash is that it will bring the wrong frameline on the Minolta CLE. Quote Link to post Share on other sites More sharing options...

Giorgio Festa Posted January 7, 2011 Share #22 Posted January 7, 2011 Sorry for the question but...who can modify the lens? Should I send it to Solms? How much can this operation cost? Tks Quote Link to post Share on other sites More sharing options...
jaapv Posted January 7, 2011 Share #23 Posted January 7, 2011 I have just sent mine to Will van Manen. I doubt Leica will do it. Quote Link to post Share on other sites More sharing options...

Will cost nothing if you do it yourself. Very simple. See How to modify a 40mm Summicron-C (with photos) Quote Link to post Share on other sites More sharing options...

el fotografo Posted January 8, 2011 Share #26 Posted January 8, 2011 I used the web link instructions to modify my lens and it is a very easy to do. The 40-C is my favorite lens on film cameras and now on the M8. To mount a UV IR filter on it, I bought a lens hood and series 5.5 adapter made specifically for the lens from HeavyStars on ebay. The adapter has S5.5 threads on one side and 39mm threads on the other for the hood. I can now use a standard 39mm UV IR filter! The hood is very nice as well, not too big and well made. A great solution for US$29.99. Quote Link to post Share on other sites More sharing options...

jaapv Posted January 8, 2011 Share #28 Posted January 8, 2011 Just some additional information for the use of the Summicron 40 on the M8. You will want to use a IR-cut filter on the lens. there are three options. You can try to screw in a E39 filter, but the thread is different. It will go in for half a turn and hang in there, but you risk damage to the filter thread. The best way is to get a series 5.5 adapter (11251). Those are easily found on E-Bay. The glass from a B&W 486 filter is an exact fit in lieu of an old type 5.5 filter, which doesn't exist anyway. I do not know of a lens hood that will fit onto this adapter, however. Secondly, Heavystar sells a Summicron 40 --> E39 adapter with a lenshood included. You can screw a regular E39 filter into there. 1 Quote Link to post Share on other sites More sharing options...
dpitt Posted January 9, 2011 Share #29 Posted January 9, 2011 Update on the 'frame locker' thing: Yesterday I was with Will van Manen to fetch my M2 and showed him what I did to the M8. He confirmed there was no danger of damage to the camera in any way! Perfect solution if you do want a cheap and reversable solution to use 35 mm frames on the 40cron. The only caution is that you do not want to make it too thick, so that the upwards force on the lever is not excessive when you insert it. When you want to code the lens it is better to have it modified as well. In fact if he codes a 40cron, he always modifies it to make the coding working properly. The code seems to work together with the selected frame to trigger the appropriate correction in the M8. That said, I decided to have the worst of my 40crons serviced, modified and coded by him. It needed service anyway because it suffered from pre-focus and haze. Adding coding to the job seemed the logical step. BTW: Will did a marvelous job on the M2. Good as new! Looking forward to use my uncoded 40cron on this one with the frame locker... Quote Link to post Share on other sites More sharing options...
jaapv Posted January 9, 2011 Share #30 Posted January 9, 2011 Hi guys, Here is the solution that 'does not exist' according to some I used a cap of a film roll box. Cut a smal pie-shaped piece of it and then stuck it under the frame lever. Make sure your 'frame-locker' fits with just the right amount of pressure to keep it in place and not too much so that you do not bend the lever. Have been using this solution on my M2 and M8 for a few weeks now and it seems to work fine. The first image shows the 'frame-locker' in place under the lever with the 40cron mounted. The second shows it on the viewfinder of my M8 to give you an idea of size. Not very practical when changing lenses or wanting to use the lever as intended...

Looking forward to use my uncoded 40cron on this one with the frame locker... Your solution for the 35mm frames when using the 40 Cron C isn't needed. The 40 on the CL was the standard lens and the viewfinder for that camera didn't go below that and the 40mm lines are fixed, always showing, just like the 50mm lines on the M3. So no matter what you do to the mount lug if you used that lens on a CL the 40mm lines are still there. On all other M's, that have 35mm frames, if you leave the mount lug alone it brings up the 50mm lines which is farther away from the focal length of the lens then 35 frames are. And with your solution there is a possibility of bending the frame lever. Quit foolish IMHO. 1 Quote Link to post Share on other sites More sharing options...
lct Posted January 9, 2011 Share #32 Posted January 9, 2011 Problem is to know if the 50mm frame lines may be more accurate in some circumstances IMHO. The 35mm frame lines are more accurate with my Epsons but i don't know if it is the same with the M8, M8.2 and M9. Quote Link to post Share on other sites More sharing options...

The 35mm frame lines are more accurate with my Epsons but i don't know if it is the same with the M8, M8.2 and M9. The M8 frames are tight so the 35 frames work OK for the 40. On M8.2/9 the 35 frames will still give you a better representation of what is in the photo then the 50 frames. But neither are correct. I see no reason to NOT cut the mount lug on the 40 so the frame lever (frame lines) doesn't move from it @ rest position without a lens mounted. Which give you the 35mm frames on all M's that have 35mm frames. Quote Link to post Share on other sites More sharing options...

drdannn Posted January 9, 2011 Share #36 Posted January 9, 2011 (edited) Maybe you do not have to modify the lens. Recently I found a way to 'lock' the frame choice lever of my M8 in the desired position. This gives me the 35mm frame any time I want it. So my 40cron is untouched. I do not have the time now to post some images of the solution. Give me a few hours and I will. Dirk, How do you lock the frame choic lever???? Just answered my question.

photoshutter Posted January 10, 2011 Share #39 Posted January 10, 2011 (edited) Original M8 frames is the best for Summicron-c, practically 100% view with 35 frame, I think this is the best normal lens on M8, very compact.
