Video DSLRs For Nature Shooters
The excitement of having HD video in a DSLR has taken the photography world by storm. We help you wind your way through the technology and the range of camera models that have HD video built in.
With a rugged moisture-, dust- and cold-resistant (and very compact) body and a host of features, the K-7 could serve a working pro outdoor photographer very well, but it comes with a near-entry-level price. Among those features are a 14.6-megapixel, APS-C-format CMOS sensor, a 3.0-inch, 921,000-dot LCD live-view monitor, built-in sensor-shift shake reduction that works with all lenses, a built-in sensor-dust remover, three-frame, in-camera HDR, mirror prelock, automatic lens correction (for distortion and chromatic aberration, with DA lenses) and two RAW formats (Pentax’s PEF and Adobe’s “universal” DNG).
The K-7 can shoot 1280x720p HD video, plus 1536x1024p and 640x416p video, all at 30 fps. Operation is simple: Rotate the mode dial to the movie icon, and press the shutter button to start shooting; press again to stop. The camera controls ISO and shutter speed in video mode, but you can lock in a desired aperture before starting to shoot.
A built-in microphone records mono sound, or plug the optional stereo mic into the provided 3.5mm jack. You can’t shoot a still image during video recording. Videos are recorded in AVI format with Motion JPEG compression.
