Pentax K-x


User-friendly yet full-featured ; ISO range expandable to ISO 12800 ; 1280-by-720 HD video

No rechargeable battery ; Plastic feel and basic control layout ; No HDMI-out

The K-x is a beginner-friendly SLR featuring most of the latest must-haves (and a very good choice for anyone wanting to shoot video), but the lack of a rechargeable battery is a pain.

Pentax K-x (with 18-55mm DA lens, Navy)


Aside from the fact that it comes in too many colors to count, at least overseas, there's a lot to like about the Pentax K-x, an entry-priced dSLR with some sophisticated features you don't normally see in that price class. Continuing its tradition of...

Very good noise profile; nice-size viewfinder for its class; relatively speedy

Doesn't display AF points in viewfinder; no HDMI connector; slow Live View autofocus; mediocre LCD; unreliable image stabilization

A fast, inexpensive dSLR with better-than-average low-light quality, the Pentax K-x nevertheless has some flaws, such as unreliable image stabilization, to watch out for.

Stylish, durable design, Better specs than similarly priced competitors, Packs technology for boosting dynamic range, Fast burst shooting

Mediocre image quality, HD video shows some motion blur

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...

Pentax K-x


With the Pentax K-x, it's not just the choice of a colorful red, white, or blue housing that makes this D-SLR stand out from the crowd. The entry-level K-x ($599.95 direct, with 18-55mm kit lens) is also the least-expensive D-SLR to offer 720p...

Very solid image quality. Impressive low-light performance. High-definition (720p24) video capture. Fast 4.7 fps burst mode. Available in blue, red, or white

Lacks in-viewfinder focus-point indicators. Flimsy-feeling build. Proprietary USB and A/V connectors ; Watch our Pentax K-x video review

Breaking the boring, black D-SLR mold, the colorful Pentax K-x is the least expensive HD-video-capable D-SLR you'll find. And it takes great pictures, too, even in low light.

The lowest-priced video-enabled SLR by a substantial margin, the $650 Pentax K-x still image and video quality won't impress sophisticated shooters, but consumers will welcome the extensive feature set. Lack of high-def video output, though, is a...

The $650 Pentax K-x is the lowest-cost video-enabled SLR on the market by a substantial margin -- the nearest price rival is the Nikon D5000, which runs $200 more. The cost-cutting mentality takes its toll in several areas, including the use of AA...

Pentax K-x Review


The Pentax K-x sits in the slot previously occupied by the company's K200D - one of the best-specified entry-level DSLRs on the market in its time - though that position has now been elevated by the arrival of a new breed of simplified models below it....

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...

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...

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.

Best entry-level digital SLR camera


The 12.4-megapixel Pentax K-x digital SLR camera is a reviewer favorite among budget DSLRs. Though not quite as capable as better cameras from market leaders Canon and Nikon, such as the well regarded Canon EOS Rebel T2i (*Est. $900 with kit lens), it...

Great image quality, sturdy construction, 720p HD video at 24 fps, takes AA batteries, available in many colors

Not the best LCD screen, some exposure/low light issues, small, so-so autofocus
