}i know this has probably been asked before but i am fairly new to this forum, so i will ask again.
i just purchased a 90mm summicron lens. it is a series 7 type. i just found out that that refers to the lens filter. another type is a 55 type.
i was told that the series 7 was made in germany and the 55 in canada.
question: which one is the newer of the two? and is there any difference in performance?
