Photoreview has published a new review on the Olympus E-PM2. Their main issue with the E-PM2 is the user interface. IMO, people who wants to have more direct control won’t be interested in getting the E-PM2 – I would think they will go for something that has more physical controls (E-PL5 or even OM-D E-M5). Plus, I have been a user of Olympus camera for couple of years – their super control panel is actually quite good, better than many other systems I have tried before. E-PM2, just like other Olympus models, has direct access to this panel so unless you are constantly changing your aperture, shutter or exposure settings, the super control panel should be sufficient.
