For obvious reasons, I have accumulated some 10 lenses...Canon and Nikkors. In past, generally used but two...a short one (normal) and a slightly longer one (135) for film stuff...what I had, never had a widie...or use... Am guessing some of us have jillions of lenses...but use but one; maybe two. Which one or ones, most often? Reasons really not necessary. No need to showoff inventory etc.
