I recently pared-down my extensive kit and now have the OMD EM-1 with Panny 7-14 Oly 12-40, Oly 40-150 f4 and Oly 4/3 50-200 SWD. I also have a Sony RX100 mk1. I took this lot on a recent trip to Cyprus to see how I got on. I used the 12-40 most, never used the 7-14, took quite a few with the 50-200 and hardly any with the 40-150. I therefore think I made the right choice in losing the lenses I did and can now travel light (which was the original idea behind adopting m4/3 over the Canon kit I had before). Here are a few from the trip: 1. 2. 3. 4. 5. 6.
