I'm traveling to Italy late April for 3 weeks. I want to lighten my load and try to leave the 70-200 for my Canon DSLR at home. I am pretty much a wide angle shooter but I know I want to capture architectural details and some long Tuscan landscapes. Which long lens would you get and why? Off the top of my head the Panasonic 14-140, 45-200, 100-300 Olympus 14-150 are what I'm considering. Thanks in advance.
