Imaging Resource has published a review on Olympus E-P3. Although they found their share of complaints on E-P3, it has managed to earn a “pick” on their site. Generally, a competent camera in its own right.
Olympus upgrades their high-end PEN line with a load of new enhancements while maintaining the retro look of the original. The sensor size also stays the same, but is said to be enhanced for better performance in low light, though we couldn’t see much of a difference. It’s the new targeted touchscreen interface that really impresses, allowing easy autofocus confirmation via onscreen zoom, and the autofocus itself is so fast it rivals many SLRs.
Pros: Extremely fast autofocus; Pop-up flash and AF-assist lamp; Full HD recording; wisely limited focus for touchscreen; excellent print quality results; removable grip.
Cons: Larger than some competitors (see E-PL3 if you prefer a smaller camera); strong noise suppression; touchscreen easily activated by mistake; list of options is overwhelming; shoulder strap D-rings are noisy.
