My copy of this lens just came in the mail the other day. I got a beater German version of the lens. Not sure what the differences are, if any, between the German and Canadian versions. Supposedly the German version is 100g lighter. Don\'t know how or why. Or if it\'s even true.
I haven\'t yet developed any rolls from it. I will say that the lens is big, but not too big to be unmanageable. The biggest ergonomic strike against is it\'s stiff focus compared to my other lenses.
