Christ, this is getting complicated. Mirrorless cameras with interchangeable lenses that promise near-DSLR quality without DSLR bulk are verifiably exploding. After the now-established Micro Four Thirds format from Panasonic and Olympus, Samsung jumped in with its Hybrid NX camera. Yesterday, Sony revealed its own spin, the Alpha concept.

And now, there's Sigma, known for its prickly but highly capable compacts powered by its oversized Foveon image sensors, is going to make their own system with Foveon. More interesting, maybe, is that they're thinking about making lenses for the other guys too. Oh well, who really wants simplicity? [DP Review]
