My EP5 is my "second" system, and I currently have the 12-42 II R, 40-150mm, pany 14, and sigma 30mm. This is my travel system. I'm thinking of finishing up my "system" with a 7.5 & the 75-300. I had thought about the sigma 60 or the Oly 45, but I think I'd use the 7.5 or the larger zoom more. I shoot a wide variety of image types, and my main goal was keeping the kit very small but still have a wide range of capabilities. How would you top off my "system"? If you want to see what kind of images I do, look at my gallery.
