Hi, I have been reading a lot about the EM1 focusing much better the 4/3 lens, especially with the latest firmware update. But I prefer at this moment the EM5 for the smaller size and price. I intend to do wildlife photography and I love the idea of having a weatherproof setup with the MMF3 adapter. I have read that the EM5 isn't very good at focusing 4/3 lens but I need to ask: Is it really that bad? Will I make a big mistake matching up a 50-200mm with the em5 instead of em1? Thanks for your advice.
