I have a $350 rebate from Canon after purchasing a printer that I'd like to use toward my micro 4/3 kit. I currently have an OMD E-M5 with the Oly 17mm 1.8, Pan/Leica 25mm 1.4, Oly 45mm 1.8, Oly 12-50mm, Panasonic 45-200mm, Panasonic 100-300 and a Panasonic GX1 for a back-up body. I previously rented an E-M1 with version 1 firmware and the 12-40mm 2.8 pro zoom and liked both. I tend to gravitate toward nature and wildlife photography in my travels. Although the Olympus outlet is offering some good deals on the E-M1 the reports of EVF issues and control dial problems have me concerned as the camera will likely see a great deal of time outdoors. My current primary wildlife rig is a Canon 1D mark3 with a Tamron 150-600mm zoom. I keep hoping for a lighter weight more compact alternative and was thinking the E-M1 with the E-M5 as a back-up might be a good combo. Otherwise I could put the money toward more glass. Any thoughts?
