The template for a successful mirrorless camera is tried and tested: a large body, an APS-C sensor, and a few lens anti accessories to help bridge the gap between compacts and DSLRs.
The Pentax Q is different — its tiny compared to rivals such as Sony’s NEX-C3, at only 98mm wide and 31mm deep, and its sensor has also been subjected to a shrink-ray. Where the APS-C sensors found in other mirrorless cameras measure 24mm wide and 17mm tall, the Q’s is around 6 x 4mm. It still contains 12 million tightly spaced pixel sites, though.
That means image quality, while good, can’t compete with other mirrorless cameras for quality, dynamic range or high ISO performance. The sensor’s small size also means there are limits to how shallow your depth of field can be. Even with the aperture open at its widest, the Q just can’t recreate the same effects as a good SLD or DLSR.
