cv 50 1.5 material difference between black and white version??
myself have a white version of this lens. its optical performance is without any doubt and I really love it.
one thing is, my white version mechanically feels a little soft and light which is not so pleasure for me.
some of my friends told me that it is because the white version is manufactured by Magnesium alloy, but at the meanwhile the black version is made by copper and thus has a much better weight feeling and operate pleasure.
Is that true? some knows any detail information about this is quite appreciate!
