15mm Heliar versions

[silvalis]

Someone just mentioned to me that there were two versions of the CV 15mm Heliar.

I can't find anything on the subject.

Is this guy telling me porky pies, or was there a second version with "Only 1 coating on the lens and is supposed to be sharper"?

Well, he's correct in that it was made in both LTM and Nikon F mount; but optically I believe both versions were identical.

hah, should have specified.
It's the LTM version.

To my knowledge, there is only one version of the 15f4.5 Heliar in LTM. I think that a uncoated or single coated 15 mm would be rather futile as potential for flare would the significant.
The 35f1.4 and the 40f.4 are both made as SC(single coated) and MC( multi coated lenses) but so far, these are the only two in these versions.
The F-mount 15mm and 12mm are the same optically, but with a slightly different look and operation. Quite a big bigger too. If you can find the correct adapters, they can be used on Leica LTM/M's and also on Nikon Rf's.

black versus silver?

(identical inside, of course)
