Excerpt: Budget-priced DSLRs make up a pretty crowded sector and one that deserves investigation from anyone about to enter the wonderful and empowering world of this type of shooting gear. As a DSLR, the Pentax K-x is about as good as it gets and, aside from engaging with a venerable name in cameras, taking it on would also deliver a camera to you with the benefits of Live View and High Def movie capture.
Summary: A very impressive DSLR with an excellent feature set and possibly the best high ISO performance in its class. The lack of visible AF points is a frustrating omission, but if you can live with that the K-x is a little cracker, and a bargain too.
Pros: Good detail and color in JPEGs at base ISO, Class-leading image quality in low light, very good retention of fine detail at high ISOs, Good quality 720p video output (but Motion JPEG format produces large files), Decent build quality, Quick and responsive operation, Coherent user interface, Very small dimensions for a DSLR, 11-point AF system with flexible AF-point selection, ISO range up to ISO 12800, 4.7 frames per second continuous shooting (though buffer runs full...
Cons: Tendency to clip highlights in high-contrast scenes, Relatively little RAW headroom means it is difficult to pull back blown detail even when shooting RAW, No visible AF points in viewfinder, Shake-reduction not too efficient, AF in live view very slow (like most SLRs), Unreliable Auto White Balance in artificial light (but very good presets and WB fine tuning), No HDMI-connector, ISO in movie mode is capped which can result in underexposed videos
Summary: Thanks to its durable design with multiple color options, fast burst shooting rate, 11-point Autofocus sensor, and the option of taking home two lenses for less than what you’d pay for a competing model, the $599 Pentax K-x is a compelling buy. While there are other DSLRs, such as the $629 Nikon D5000, that offer better image quality for both photos and videos, there’s no question that the Penatx K-x is still a good value.
Pros: Stylish durable design, Better specs than similarly priced competitors, Packs technology for boosting dynamic range, Fast burst shooting,
Cons: Mediocre image quality, HD video shows some motion blur,
Conclusion: The K-x is worse than some - the lack of on-the-job focusing isn't ideal and sensor wobble can be severe. But if HD video is an occasional hobby and you're looking for a good, well-made DSLR to grow into, the K-x is a strong possibility.
