Originally posted by Clavius I'll spill the beans, it's a DSLR based on the 12mp hyper-sensitive sensor that is also used in the A7s. It does 12 fps. And the AF, including tracking AF, is amazing. It's the exact size of the K-5 though
That is strange, the model they sent me was based on a Pentax LX, the camera is a bit taller with an un-crippled KAF4 mount*, made of solid mag-alloy the camera houses a full FX format 24Mp BSI Sensor, with a global shutter. It has built in WI-FI with a modular EVF/OVF that you can physically detach from the camera and maintain live view (this works in EVF mode only, it also has a small rechargeable battery that charges from the primary camera battery). and on the subject of batteries, you know the baseplate on the LX? - that is now an entire battery, at 1/2" thick 5" long battery I was able to get about 1500 shots out of it per charge. Pentax also has a second battery option which doubles as a grip which nearly triples the battery capacity, it includes a shutter release, 4 way controller with AF and metering selection dials on it and some programmable controls (sadly, no AA battery compatibility). the camera has a built in viewfinder curtain - which actually covers the focusing screen - the camera automatically deploys this when you detach the OVF/EVF, which also has a rear blind of its own to protect the internal optics.
*dimensions of the new mount are noticeably larger than the previously existing KAF3 mount the flange is identical the the original K mount - the increased diameter is to allow pentax to make a greater variety of wide aperture lenses without hitting the Achilles heel of the K mount.
