[Oops - the subject should be 'not the lenses'] Too many lenses, too many wants, too much time (I'm retired), enough money and a spreadsheet faced off against how much weight I was willing to carry. No conclusions were reached. The heavier sets didn't appeal to the traveler in me, the lighter sets didn't appeal to the photographer. Then an 'ah-ha' moment resolved everything. There is no need to carry all the lenses all the time. I usually wake early and shoot near my lodging in morning light before breakfast and shower. At the end of the day, I'm also out wandering in the good light. For those two times, I fine with a fast wide and a fast short tele. Outside of those times, the IQ on a very wide zoom plus a kit zoom is sufficient. Four lenses, carried two at a time. D'oh!
