Hi all, I am a member at the mu-43 and currently own an ep-1. I however am finding that the camera is heavy and most importantly the af is very slow. I had though of buying the 20/1.7 lens but heard that it is even slower to AF. I also am having hard time to focus with the kit lens in low light and not happy with the IQ with high iso. I recently saw the 5n iso samples and user pictures and though they were very clean, compared to ep-1. SInce, i havenot invested in the m4/3 system, I think switching would not be difficult, but I don't know if this is the right choice. I have heard the af speed of ep-3 to be much faster but again I am not sure if the IQ can be compared to a NEX. WHat do you guys think?
