Heading to San Francisco, and I'm torn on what to bring. Last fall we went to London, and I had m43 for travel. Brought the 9-18, Panasonic 20 and the 50-150. Bulk was done on the 9-18, some personal indoors shots on the P20, and a couple of architecture shots on the 50-150. Very pleased with the results. This was my last use case for m43 (travel). This year, I dedicated 2016 to try and go all Sony, and have 2 kit options: APS-C option: a6000 w/28/2 for indoor personal shots, 55-210 for tele. Maybe also bring along the excellent Sigma 60. I guess my RX100 for wide angle and pano. I don't care much for the Rok 12/2. Great results, just not my cup of tea. Will probably sell it. I wish Sig would make a nice, compact 12 or 16mm for APS-C to go with their 19, 30 60 series. Full Frame option: a7 w/28-70 all-rounder, Voigt 40/1.4 for personal indoor shots, and maybe also the 55-210 for telephoto. I think I like this kit better, TBH. I prefer AF for when out in the streets on the wide angle. Indoors MF when taking pics of friends is OK. I have time to buy something else, but the only think I'd consider I think is the Sony 10-18, but for me, it's a bit big to carry with everything else, and I'm much prefer a 10-28.
