Product Description

Using optional FLU card SDHC technology, the K-3 offers complete remote camera control, including aperture, shutter speed, ISO, focus points, shutter release and image transfer to laptops and compatible devices. Other enthusiast pleasing features include H.264 video capture, dual memory card slots, Live View, an electronic level, and weather sealing in a magnesium alloy body.

The K-3 is the latest and best in a well-established line of high-end APS-C DSLRs. The K-3 offers a wealth features for still photographers, including a large, 100% coverage viewfinder, solid build, and plenty of customization.

    More than a simple upgrade

    I do not consider myself being a professional camera tester, I'm just a happy user. This camera is a class of its own. It's more than a simple upgrade to the K-5 I have used before. I like - fast and accurate AF - very quiet shutter - sharpness (a very good lens provided) - overall responsiveness (fast memory card provided) I do not say that noise is worse. In my opinion, a little noise somehow produces a perception of crispyness. You will never see it on moderate-sized prints. However, when ...

    Better in every way

    The early impressions after 3 weeks of casual snapping are very positive. This body is an upgrade to a K-5 which got used a lot over 2+ years. Pentax/Ricoh made numerous upgrades to a very good camera, none of the upgrades are game-changers but taken together the result is very impressive. To those unfamiliar with the Pentax K-single-digit family they are solid, reliable performers in robust, confidence inspiring bodies with excellent viewfinders & ergonomics. Compared to the K-5 the new ...

    Catching fire with a K-3

    I am an editor for a small weekly newspaper, and this morning at 5 a.m. the fire siren went off. I went over to my office and grabbed my new K-3, which despite having for a week, have shot nothing more than test shots around the office. I got to the scene and started shooting. I told myself I was not going to shoot 6400 ISO, but because of the conditions, I just went between 3200 and 6400. I have NR set to custom, with low NR for 1600-6400. I also have slow speed NR on. Impressions and thoughts ...

    Pentax K-3: Everyday fun with a powerful tool

    The Pentax K-3 is both a very continuous product for all people who have owned a recent Pentax DSLR and at the same time a large step ahead in so many areas that it makes the tiny upgrades some "new" camermodels get these days look ridiculous. So what is new for the K-3 compared to other Pentax DSLRs? (1) 2 SD card slots (2) focus peaking (3) 24 MPx sensor (4) Number of F2.8 AF Sensors now is 3 (5) AF sensitivity is up to EV ...
