darylgo Posted October 16, 2011 Share #1 Posted October 16, 2011 Advertisement (gone after registration) I am thinking of selling my DR Summicron to fund the purchase of a Summilux. I am loath to part with such an excellent lens as the DR, so instead am thinking of a conversion for use with the M9. Anyone know what effect this has on the value of the lens? Anyone use this lens on the M9, what do you like/dislike about the imaging? Thanks. Link to post Share on other sites More sharing options...

luigi bertolotti Posted October 16, 2011 Share #2 Posted October 16, 2011 Please DON'T modify a Summicron DR ! I don't know if is technically faesible, but anyway the result would be a "half-breed" item, to say : - A simply "old 50mm lens" for M9, surely not better than a modern 50 - A "hand modified" version of an original Leitz lens wich has a specific and significant value for collectors and lovers of "oldies to use". To say, an item which has lost its identity/originality... value gone... like a goggled Summaron deprived of the goggles... . If you want to have a good 50 for your M9, you can find many ways to have it, in case selling your DR and funding with this something else (a used standard Summicron of the same age, or a newer one, or the Summilux you are thinking of, or a new Summarit 2,5... lot of chances) Personally, I found a nice way to keep my Summicron DR "alive" : I have a SOMKY+UOORF set... it accepts the DR lenshead... and is a fine, good, very usable and easy to carry "semi-macro" set for my M8. .

darylgo Posted October 16, 2011 Author Share #4 Posted October 16, 2011 Thank you for your replies/help Michael and Luigi. This morning I have learned that I can mount my DR on the M9. If I place the goggles on the lens and turn to closest focus I can mount the lens safely. The lens will then turn almost fully in close up range. Given that I can use this close focus as is, what advantage does the Somky + Uoorf provide? I understand completely the DON'T modify request, and I think a good compromise is to keep the lens for close up. Link to post Share on other sites More sharing options...

I understand completely the DON'T modify request, and I think a good compromise is to keep the lens for close up. The Somky + Uoorf set up provided the same advantage as the DR Summicron re: close focus. It allowed the non-DR version to have the same close focusing capacity as the DR version - but with somewhat more trouble. You have to remove the lens unit from the focusing mount, screw it into the Uoorf, which then locked into the Somky. More trouble than sliding on the goggles onto the DR version. BTW - the DR and Non-DR lenses were identical. Link to post Share on other sites More sharing options...
darylgo Posted October 17, 2011 Author Share #6 Posted October 17, 2011 If the Somky + Uoorf would convert a non DR to a DR, wouldn't the purchase of a DR helicoid + goggles do the same thing? This makes me think that I might be able to do the reverse and convert my DR into an M9 compatible lens with the addition of a non DR helicoid, is that feasible? Available?

Robert J Posted October 17, 2011 Share #7 Posted October 17, 2011 Advertisement (gone after registration) The focusing mount of your DR summicron lens is matched specifically to the exact focal length of the lens head.While it is mechanically possible to mount the DR lens head on a non DR focusing mount,there will be a problem with the back focus and proper rangefinder coupling if the Non DR focusing mount was adjusted to a different exact focal length.

darylgo Posted October 17, 2011 Author Share #10 Posted October 17, 2011 Robert , jc and luigi: thank you. This is a real bonus to have close up capability with the M9. I took a few shoots quickly, f4 is sharp at .5 meters. I hope to shoot a few items with studio lighting to see how good this combination is. I only wish this lens would focus throughout the full range with my M9, that would be a real treat. Link to post Share on other sites More sharing options...
