So I'm looking at getting my wife away from her Canons and into micro four-thirds. I have a PEN E-P2 which sees exclusively adapted lenses. I chose the Olympus for IBIS. The wife sees this as an advantage, but isn't interested in adapted lenses. When shopping, I saw the G5 is on sale for $500 with kit lens. For that price she could pick up an extra lens and still be cheaper than the OM-D E-M5. I've seen many people preferring the Olympus in a head-to-head comparison, but considering this, is the Olympus really $500 more camera? I have trouble believing it could be. We're looking at renting some cameras and glass for an upcoming museum and zoo day-trip. I'm looking to grab an E-P5 to play with while she grabs a G5. Any suggestions for what we should be paying attention to? I want to make sure she gets a good feel before deciding. We're looking at renting the Pany 8mm fisheye, 15-140, and 100-300.
