Good reviews continue to come in for the SONY full-frame fixed lens compact cameras. The latest iteration, the RX1r, continues the run (no AA), but a recurring review comment is about there not being an alternate focal length. The Merrill DMs, with three popular focal lengths, keep the benefits of lenses matched and optimized to their sensors, sealed operation (no sensor dirt), compact size and excellent image capture. The SONY is larger and costs more (a bit over twice on both points), certainly, but would serious shooters accept the idea of carrying two SONYs of different focal lengths? The investment would be comparable to a D800 with two fast Zeiss primes. Would SONY do this?
