It’s a solid camera with excellent image quality. And Pentax boasts the most APS-C lenses of any DSLR manufacturer.

Video image quality is good and rolling shutter effect is well controlled in all but the most exaggeratedly fast pans. The built in microphone is wind sensitive and picks up other camera noises during recording in the auto setting; audio may also be captured manually or disabled altogether. The camera has an external microphone jack that can facilitate the recording of stereo sound during video capture.

Typical for Pentax camera offers a lot of performance and features at a relatively bargain price, including weather sealing and a continuous high-speed shooting capability in excess of 8 frames per second. The camera is compatible with Pentax lenses going back decades and because stabilization is built into the camera body you retain stabilization capability no matter how old your lens. The 23.3 megapixel effective resolution is a healthy jump over previous Pentax DSLRs, but Pentax has wisely also built in a fairly robust buffer capacity to support that 8 fps motor for those folks who lean heavily on the shutter button while shooting. The camera lacks an AA filter and the AA filter simulator demonstrated it wasn't up to the task of completely removing moire in what was admittedly a worst case scenario subject, thus making post processing a possibility in some cases.

What's the chance of the K-3 getting hacked for raw video?

It all depends on you :-) I made unpacker quite a time ago for almost all Pentax cameras.

Thing is I am not Shiva and do not have 128 hours in each day.

I was really interested to learn about the virtual anti-aliasing filter in the K3. The camera's anti-shake feature can be turned on or off to simulate the slight blurring of an AA filter element. It's a cool idea. I wonder if it works continuously in video mode?

Pentax brand deserves to finally get some attention in camera shops—the K-3 is camera that needs to be seen and held to be fully understood. It’s easy to look at black, DSLR-shaped bodies and assume that they’re all the same, but the truth is that Pentax DSLRs are among the nicest feeling cameras money can buy. Solid metal construction, impeccable handling, and that famous Pentax weather sealing make its high-end cameras ready to go wherever at a moment’s notice—neither snow, nor rain, nor heat will stop you.

It provides the image quality, performance and feature set to compete with any other dSLR in its price range. Sporting a 24-Megapixel APS-C sized imaging sensor, real-time scene analysis, incredible AF system and a shutter that can provide up to 8.3fps, you will be hard-pressed to find anything that this camera doesn't excel at. In-Camera SR (Shake Reduction) allows any and every lens to work with the camera's image stabilization system. The great features don't stop there either. Dual memory card slots, Eye-Fi compatibility, pentaprism optical viewfinder, full 1080p HD video recording, HDR image capture and a fully weather-sealed body help to round out the best features; but there are still plenty more. All of the features provide unique and amazing shooting possibilities that will allow and enhance your creative photography.
