I dunno if it's a freak of nature or something, but the 75mm f2.8 is smaller and lighter than the 75mm f4. Also, my 200mm f2.8 is not significantly larger or heavier than my old screwmount 200mm f4. But in both of these cases, the faster and smaller lens is considerably newer. -Aaron - This message is from the Pentax-Discuss Mail List.
