Olympus has came out a new range of m4/3 pens in 2011. Namely the highend EP-3 replacing EP-2 and the Lite range EPL-3 replacing the EPL-2 Pen. They add on a new range called the Mini, EPM-1. Basically EPM-1 is a scale-down of EPL-3. It has less buttons and has no tiltable LCD screen like the EPL-3. I choose EPM-1, first due to the price. It's size is much smaller than the EP-2 or my 1st m4/3 body panasonic GF-1. Although it is placed at the lower range of the Pen line, it feature a 4.1frame per seconds continueous shot(Comparable to mid-range DSLR) and the AF speed is the same as EP-3 where it has improved tremendously. Sensor and Image quality are the same as EP-3. Howevere there are more controls and feature choices for EP-3 and EPL-3. More info can be found other sites.
