The integration of the OM-D E-M5’s sensor in the Pen E-PL5 compact hybrid is important in terms of its image quality. It allows less-wealthy photographers to access the same standards for photographic rendering as the OM-D, which uses its more ergonomic traits (e.g., tropicalization, viewfinder, user interface, etc.) and functions to position itself in the premium compact hybrid segment.
The Pen E-PL5 takes 100% advantage of its new sensor and offers the same image quality as the OM-D E-M5 (so long as one uses the same lenses). The two Olympus micro 4:3 cameras lead the entire pack as the best cameras ever designed in this category, and as such they are simply manhandling their Panasonic G competitors (pending the sensor test results for the GH3, which we hope will bring something new to the various criteria we measure).
The Olympus compact hybrid achieves scores that come close to its APS-C competitors of reference, such as the Sony NEX, and enjoys a serious and comfortable lead over other quality cameras in other market segments, such as the Nikon 1 hybrids or the expert compacts such as the Fujifilm X10.
