alexanderruas Posted April 16, 2007 Share #1 Posted April 16, 2007 Advertisement (gone after registration) I have an old Leica CL and was wondering how the Leitz Summicron-C 40mm f/2 lens that I have on that camera will work with the M8 I am buying? Anyone out there tried the combo? thanks, alexander Link to post Share on other sites More sharing options...
Advertisement Posted April 16, 2007 Posted April 16, 2007 Hi alexanderruas, Take a look here M8 + Leitz Summicron-C 40mm f/2???. I'm sure you'll find what you were looking for!
mike prevette Posted April 16, 2007 Share #2 Posted April 16, 2007 I use it all the time on the m8, and it's fantastic. What a sharp little lens, and compact too. It shoots very nice on the m8. Link to post Share on other sites More sharing options...
alexanderruas Posted April 16, 2007 Author Share #3 Posted April 16, 2007 fantastic!!!! thanks so much for showing photos. I guess there are no problems with back-focus? your photos look VERY sharp!! I'd love to see more! alexander Link to post Share on other sites More sharing options...
hammam Posted April 16, 2007 Share #4 Posted April 16, 2007 It's a great combo. Yes, what a lens for the price. For any price, for that matter. And compact, too. A bit flary, maybe. Also, be aware that, if you use a IR-cut filter (39), the thread pitch of the Cron 40 is not regular, so the filter will only screw in a couple of turns. Don't force anything. It'll stay in place. Then you can screw the lens hood on top of that. Have fun. Link to post Share on other sites More sharing options...
alexanderruas Posted April 16, 2007 Author Share #5 Posted April 16, 2007 how do you work around the fact that there is no frameline for the 40mm lens? alexander Link to post Share on other sites More sharing options...
ho_co Posted April 16, 2007 Share #6 Posted April 16, 2007 Alexander-- A Summicron-C will likely work fine on your M8. But remember, Leitz recommended at the time that the CL lenses not be used on the M camera because they would not focus properly on about 25% of M cameras. When I asked US Leica Technical how the matter stood with the M8, the response was, "C lenses are not recommended for the M camera; since the M8 is an M camera, we don't recommend use of the Summicron C on the M8." When I then asked in a previous thread whether anyone had an M8 whose focus roller wasn't centered, no one responded. (Centration of the focus roller is the factor involved in usability of the lens on any given body.) So be aware that the lens may not work properly on your M8, though that seems quite unlikely. And it is a delightful lens, as you and everyone else here have said! --HC Link to post Share on other sites More sharing options...
tbarker13 Posted April 17, 2007 Share #7 Posted April 17, 2007 Advertisement (gone after registration) Recently bought one to use when I want to be as compact as possible. I love it so far. I did not, however, love the 50mm frame lines. So I did the modification to bring up the 35mm frame lines. Took all of 3 minutes to do. The m8 35mm frame lines are pretty close.

hammam Posted April 17, 2007 Share #8 Posted April 17, 2007 how do you work around the fact that there is no frameline for the 40mm lens? alexander The 40 Cron brings up the 50/75 framelines in the VF. So you can shoot using the 50 framelines. The actual image will encompass a quite bigger FOV, so that's the safe route. You cans always crop later. Or you can use the frameline lever, bring up the 24/35 framelines and use the 35. But give yourself some safety margin around your picture. Link to post Share on other sites More sharing options...
mike prevette Posted April 17, 2007 Share #9 Posted April 17, 2007 The frame lines don't bother me at all. Mainly due to expierience, I've shot 40mm as my normal lens for 10 years so I "see" it very well. I haven't modified mine for the 35 framelines I prefer the 50mm ones and guestimate the extra. As another alternative I recomend the CV 40mm 1.4 It's about the same size but with the 2 stop advantage. And no I've never had focusing issues and I've used mine on my CL, M6, and M8. I think that was marketing BS on leica's part. _mike Link to post Share on other sites More sharing options...
ho_co Posted April 17, 2007 Share #10 Posted April 17, 2007 Mike-- It depends on the camera as I said; some work fine, some don't. I've got two that don't. Glad you haven't had any difficulty. My guess is that with today's production methods, no M8 will show the problem. --HC Link to post Share on other sites More sharing options...
barjohn Posted April 17, 2007 Share #11 Posted April 17, 2007 I use the Minolta varient on mine and it is a great little lens. It takes a 40.5mm B&W filter just fine. Focus is spot on and it is small and light weight. I had the Nockton too and sold it in favor of the 40/2. The Nockton was a little softer in the focus but it was close. It was also larger and heavier so I opted for the 50 Summicron instead. The 50 cron is very sharp. I made the mod for the 35mm frame lines and then hand coded it as a 35 cron and that works very well (you need to bring up the right frame line to fool the software to use the right correction which is very close).

prav66 Posted April 17, 2007 Share #12 Posted April 17, 2007 I'm using this lens too, the Minolta CLE version & love it. I filed mine to show the 35mm framelines. The Leica framelines for the 35mm are extremely conservative for that focal lentgh, so this 40mm actually matches it surprisingly well. Can't say the same about the VC 40/1.4 which is actually a couple of mm longer than this lens. One just needs to be careful to not frame TOO tighly, especially when focusing at closest distance. I find the 35mm framelines much closer to this lens framing than the 50mm ones. I'm using it with 40.5mm UV/IR filters & find that there is no cyan cast, so coding is not essential at this focal length. I tested it at all apertures for focusing accuracy & found it was spot on, with none of the decentering or other problems I've heard from some regarding the 35 Lux apsh or other lenses. Highly recommended! Link to post Share on other sites More sharing options...
lars_bergquist Posted April 17, 2007 Share #13 Posted April 17, 2007 There is an alternative, and a very practical one too: The V. 4 35 mm Summicron (that's the last pre-aspherical version, 1979—96). This is a favourite of mine, extremely compact and very good on the M8 even wide open. From f:4 it's brilliant. Bokeh is famous. It's my walkabout and use-it-on-anything lens, even though I do own the current Summilux! The old man from the Age of the M3 Link to post Share on other sites More sharing options...

wattsy Posted April 17, 2007 Share #16 Posted April 17, 2007 Can someone explain the process of how to modify this lens so that the 35mm frame lines appear when the lens is mounted? You need to file back the lug on the bayonet mount which determines the frameline position. If you compare the mounts of a 50 and a 35 you'll see the difference.

alexanderruas Posted April 18, 2007 Author Share #18 Posted April 18, 2007 how do you know that the lens does not work? is there any risk I will damage them M8 camera? thanks, alexander Mike--It depends on the camera as I said; some work fine, some don't.

ho_co Posted April 19, 2007 Share #19 Posted April 19, 2007 is there any risk I will damage them M8 camera? Alexander-- This lens will definitely not damage the M8. how do you know that the lens does not work? First and more practical method: Put it on the camera and take some pictures. You'll know if there's a problem, because they'll all be quite noticeably out of focus. Second and more theoretical method: Remove the lens from the M8. Look into the lens cavity. See whether the focus-cam-tracking roller at the top just behind the bayonet is centered in the opening. If it is, the camera and lens will work fine together. As I said above, I think there is virtually no chance that the lens won't work on your M8. --HC Link to post Share on other sites More sharing options...
lct Posted April 19, 2007 Share #20 Posted April 19, 2007 ...See whether the focus-cam-tracking roller at the top just behind the bayonet is centered in the opening... Could you please explain what you mean by 'centered in the opening' Howard? I know that you've tried to explain it to me already but i still don't understand sorry. On this pic you see the back of the lens with its sloping cam (red arrow) and the RF tracker of an M4-2. As clear as i understand, as long as the tracker rolls normally on the sloping cam there is no problem. At least i haven't got any with my 3 copies of the 'cron 40/2 on 3 M bodies and 2 Epson ones. Am i missing something here? Link to post Share on other sites More sharing options...
