Hi!
I have Leica M Summicron 90/2 (old silver version with detachable lens head, serial: 1680205).
I want use this lens with my Canon EOS 20D
What have I do for this?
On ebay i see some adapter from Visoflex M Leica lenses to Canon EOS (here: http://cgi.ebay.com/Leica-M-Visoflex-Canon-EOS-Lens-Mount-Adapter-NEW_W0QQitemZ360095844429QQcmdZViewItem?hash=item360095844429&_trkparms=72%3A1205|39%3A1|66%3A2|65%3A12|240%3A1318&_trksid=p3286.c0.m14)
Besides what else should I have?
here i found information about some adapters: http://elshaw.tripod.com/Visoflex/Visoflex.html
And here: http://www.fredmiranda.com/forum/topic2/587727
What are they for? Have I necessarily use them, or the adaptor usage is enough?
i need help!

You can not have infinity focus on the 20D with this lens.
What you can do is to use the lens for macros, for this you need to stack a Mbayonet to M39 adapter, and then a M39 to Canon EOS adapter.
Voigtlaender sells the Mbayonet to M39 adapter (not cheap), the M39 to Canon EOS adapter is easily found on the Ebay.
P.S. You don't need Visoflex for your purpose. _________________ Orio, Administrator

OK...
in this scheme:
Canon EOS body -> Leica M to EOS adaper -> 16462/ZOOEP focusing barrel -> Summicron 90/2 head
Will I get infinity? _________________ SMC Takumar 50/1.4, Takumar 28/3.5, Jupiter-9, Pentacon 135/2.8 iris, Carl Zeiss Sonnar 135/3.5, Mir-1 first version, Leica Summicron M 90/2, Helios 44-2... |

No, you will make it worse.
THe reason you can not obtain infinity focus is because the register distance of Leica M is shorter (much shorter) than that of Canon EOS. So adding tubes or bellows will make it worse.
Another thing, there is no such thing as a direct Mbayonet to EOS adapter (at least that I know of).
You need to make this stack (camera to lens):
EOS 20D <---- EOS/M39 adapter <---- M39/Mbayonet adapter <---- Summicron M 90
And you will get a nice macro lens with big magnification and the benefit of very little light loss compared to reflex macro lenses.
However I expect that you'll be able to make only very tight closeups. _________________ Orio, Administrator

Wait a minute.
I made a mistake about the Mbayonet/M39 adapter.
The one Voigtlaender makes allows to mount M39 lenses on Mbayonet cameras.
You need one that does the other way around, and I don't think it exists commercially, because it would make you lose (again) the infinity focus (although by little)
So you can not mount your M lens at all on your EOS.
Unless, you build (or commission the build of) a custom adapter.
Which will be quite wasted money, because, for register distance reason, you still won't get the infinity. _________________ Orio, Administrator

I think that's possible!
you say: "the register distance of Leica M is shorter" - true if lens head is in original barrel.
But! If lens head is deattached from original barrel and mounted to Viso (Visoflex) short-barrel focusser and short-barrel focusser mounted to adapeter Visoflex->Canon EOS - the register distance is the same as Canon EOS register distance

As Orio mentioned, if you use this lens with its original focussing helicoid you can't get infinity focus on a Canon DSLR.
You may be able to achieve infinity focus if you can adapt the lens head onto a thinner focussing helicoid or other means of focussing. The lens head's thread is supposed to be M46x0.75. |

This barrel is "original" from Leica called as: 16462/ZOOEP
This barrel was developed to be used with Summicron-M 90/2 and Elmarit-M 135/2.8 with Visoflex system

I've bougth my Summicron 90/2 for $95
I'm not sure I can exchange my Summicron-M for Summicron-R for these money...
Here is my lens: barrel(at left) and lens head(at right):

You may have one other chance to use this although infinty is a bit of a long shot (enjoy the PUN ).
The threads on these optical cels are I believe m39.
What you can do is get a m39-m42 adapter. This will allow you to use the lens on a m42 bellows.
You may find one very cheap on fleaflay.
What you are doing is the same as others have done with enlarger lenses.
If you can find a bellows that collapses to very shallow dimensions when compressed completely.
You could in theory come close to infinity with a 90MM FL lens.
Orio, you can do the same with the Hektor that is coming to you. The 135 will find infinity without trouble _________________ Moderator |

Good idea, Andy, but a 90mm might be a bit short. Depends on the bellows, though. _________________ Personal forum activity on pause every now and again (due to job obligations)!
