ME ME ME
I had the original E-M5 shortly after they came out. The 12-40 f/2.8 is THE fucking lens to have. I got mine in 2013 I think and it is my favorite lens overall.
I had the E-M5 MkII and now have the MkIII. I really dig the size, and I don't really care that the body is made with polycarbonate. Recently I got a 17 f/1.8 and a 12 f/2, although the latter's MF clutch ring is busted. The eBay seller refunded me a bit for that. Other than that it's in perfect shape.
I'm a LITTLE bummed that the 5MkIII came out in late November, and the E-M1MkIII came out just 2 months later... but the 5 didn't get the new processor or a USB C port. I really would have loved it if Olympus put the new processor in the 5MkIII then 'detuned' it a little bit. I'd really like having a USB C port... since ALL THE THINGS SHOULD BE USB C NOW.
But yeah, the 1mkIII is a damn nice looking camera. If I had any pro leanings in me, I'd want to get one. The 5MkIII does everything I want, though.
My favorite lens is the 12-40 f/2.8. I've got one of the cheap plasticky 40-150 f/4-5.6 and it is way better than it should be for $105 that I paid for it years ago. I've also got a 14-42 f/3.5-5.6 EZ that is also way better than it should be. I use the latter for 'compact mode'.
