I got into micro-fourthirds last year. I purchased an EP3, 14-150, and a 45mm to take on a trip and leave my 20 pound DLSR bag at home. It worked out great I had many good images from the 14-150 and some very special images from the 45MM, I just love that lens. I've recently purchased an EM-5 and like it very much also. Now what I need help with is new lens chooses. I have the money to purchase some new lens and was going to get the Oly 12mm and the 25mm to go with my 45mm. then at some point get the 75mm. Now since Olympus has released the 12-40mm Pro I'm not sure. The question is, would you by the 12-40mm or the 12mm and 25mm to go with the 45mm.
