What Canon 50/1.5 do you have?

I have been discussing with chug the compatability of the early Canon lenses on Leica LTM cameras.

I wonder if the Canon 50 1.5 is a lens which potentially is made to the earlier standard and not compatible in its earliest versions.

You can look here to ID the version you have.

Sincerely,

someone with an interest to learn about and some day own this lens.

Cool link, Ralph. Thanks. I've got a type 3 (with no rear element group.)

Frank,
Did you get me PM?

Frank, will your lens screw into a standard LTM to M adaptor and mount to your M2 without a problem?

 

[FrankS]

Yes it does, I just double-checked.

Another interesting investigation. I wonder who else can confirm compatability. Maybe this lens was always made to the Leica standard.

I have a type 4 and it's working very well. cheers, Frank

Dechert has a lot on early Canon's flanges. I think they were standardized not before 1946. Earlier cameras are a mixture of Contax and Leica elements, with (mostly) Nikkor lenses. It seems so that the 1.5/50 was among the earliest own-developed Canon/ Serenar lenses, but some of them being X-ray lenses (uncoated "R-Serenar" at Kitchingham's site), obviously with no need to be RF-coupled. So you will get some very early Serenar screw mount lenses not compatible to Leica, but they are very rare: Probably 1.5/50's, 3.5/50, 2/50, 4/135 and maybe others with production dates in the 1945's era. See description of "J" flange at Canon Museum (3.5/50 lens type I)
