Spending two weeks in Italy (Rome and Amalfi coast) and want to make sure I have the right lenses without having to swap too often. Currently have the 14-42 kit, 40-150 and Oly 25 f1.8. While I'm sure this trio would be fine for me, especially as a beginner, I've been considering the 12-40 pro to replace the kit lens, and bringing those three. I'd imagine keeping the 12-40 on most of the time in that case. Thoughts? Would I be fine with 14mm as widest? I feel like the 12-40 would be a good long term investment and something I could grow with, but obviously having the smaller size of the kit lens would be a benefit while walking around the streets of Rome all day.
