It really is in good condition, with a cutaway lens shade and lovely smooth action. it has a white box, and the leather case is like the modern ones (although I suppose it might not be original).

I'll give it a torture test on my R-D1 tomorrow. but first appearances are positive.

Does anyone have an opinion on these Canadian lenses, and how old this one might be?

thanks in advance
