Just curious, I find myself sometimes debating moving to Sony either the A6000 or A7. (not the R) Given the lens selection now with wide UWA 10-18 f/4 for the A6000 or even now the A7 with the new 16-35. My ultra zoom would be the 70-200 f/4 which is similar in size and weight as the new Olympus 40/150 f/2.8. The larger sensor would make up for the 1 stop loss 2.8 to f4 (at least so I think). The only thing I dislike about that Sony (its WHITE attention getter) Cost is similar to the Olympus setup and weight is the same once you choose all the Olympus Pro lenses. Thing that keeps me with Olympus at the moment is the amount of cameras (2xE-M1) 12-40 f/2.8, 9-18 UWA, 60mm macro, 35-100 f/2.8 (want to replace with 40-150 f/2.8)Underwater housing will take a HUGE loss if I switch. Anybody ever debated the same? What kept you with mu43?
