I am thinking about it quite seriously. I have a Canon 50D and an Olympus E-P3 and I love the pen system, so much that I can count on one hand the amount of times I have used the 50D in the 6+ months I have had the Olympus, I keep recharging the batteries on the 50D only to have them discharge themselves without being used. I have just bought the 12mm 2.0 and the 45mm 1.8 lenses for the pen system and they are simply stunning, along with the kit zoom they give me everything I want and need in a camera. OK the image quality is not quite up there with SLRs but there is little in it and I enjoy using and carrying the pen so much more. Question is really do I take the plunge and go all micro 4/3? My heart says yes but my head can't let go of the (marginally) better IQ, but the sale of the 50D sale could also part fund an OMD Has anyone else thought or done the same?
