I have an EPL1 which has served me well. But one thing that has really bothered me is the slow autofocus speeds. I've managed to snag the OMD on a deal, so wondering if that's the best upgrade option for me vs. something like the EPL5 which is quite a bit cheaper. I'm thinking to sell my VF2 to help offset some of the cost. How much can i get for my EPL1 body?
