I think I'd have to go with the 15 Limited, 43 Limited, and 77 Limited. Possibly swap the 43 Limited for the 31 Limited, but the 43 is a little smaller, and I'm looking at a lightweight kit. Would really be hard to go wrong with these. I like the DFA100 Macro too, but we're getting a bit bigger, and you can still fit all of the first lenses in big cargo pant type pockets. And sometimes breaking rules is nice, and if I were to toss a zoom into this mix, I'd be looking at my 20-40 Limited for a nice range and easy travel. Hhhhhmmmm. Looking at what I (and others) just wrote, there must be something about these Limited lenses. They keep coming up.
