Geek talk alert! :-D
After a ~2-year acquisition & transition period, Pentax is pushing hard this year with Ricoh driver's seat. Two lenses for 36×24 and a camera to match, the k-s2 upcoming, and now pixel-shifting resolution boost for those who feel then need .. more. That boost may even be back-compatible with K3 and maybe k-s1? Time for the serious/silly Big Names to pay attention!
And while Pentax/Ricoh sends this punch to the head, Samsung aim for the kidneys with their baby nx1 - aka nx500. Here's your AF 4K video and backlit APS.c sensor, $800 please and keep the $300+ lens, you'll like it :-) Sorry Canon, the days of carrying a massive camera for nice 2k video are about over. Thanks for playing!
