Pentax K-01 review: Pentax K-01

Despite the modernist design, the K-01 actually has a pretty typical control layout. On top, the mode dial has the usual PASM, Bulb, scene program, and auto modes, plus a dedicated movie mode and three-shot HDR mode. Two unlabeled green and red buttons are separated by an adjustment dial. The green button defaults to program shift and the red to movie record, but they're both customizable. I do find the green button a bit out of the way; it's not easily operated with your thumb or forefinger. The other issue is that despite the large size, there's practically no left shoulder to the camera, and I frequently found myself hitting the button for the popup flash.

The controls on the back also follow convention. Autoexposure/autofocus lock, review, info (which calls up the interactive control panel rather than information), and menu buttons line the left side of the LCD, with four-way navigation buttons that access ISO, drive mode, white balance and flash settings.

The biggest problem with the design is the floppy rubber cover for the SD card slot and USB and HDMI connectors. It's very difficult to close -- it requires two hands -- and the two flimsy attachment points are probably easy to rip off. To compensate, Pentax added a separate plastic cover for the SD card slot. That said, at least the card slot is on the side of the camera instead of in the battery compartment.

The menu interface is similarly straightforward, very similar to the company's dSLRs, as is the interactive control panel where you can adjust all the frequently needed settings that don't have direct-access buttons.

A few of the K-01's features stand out, though I don't think sufficiently to raise its features subrating given the price. In addition to an intervalometer mode (which shoots a maximum of 999 shots), the camera also has an Interval Movie mode, which does the same thing but can shoot for up to 99 hours and automatically saves the final file as an AVI movie. It also has a multiple exposure mode. The handful of shooting special effects are nothing special, but you can adjust a variety of parameters for each. It offers a three-shot automatic HDR mode with a range of up to three stops, and unlike some implementations, it's not completely automatic; you can still adjust ISO sensitivity and exposure compensation. And an interesting CTE (Color Temperature Enhancement) white-balance option will essentially override white-balance adjustments and preserve the color temperature of the ambient light. (For a full accounting of the K-01's features and operation, you can download a PDF of the manual.)

Conclusion
If you've got a stable of Pentax lenses -- especially good ones that can properly resolve to the sensor -- and feel like doing some creative shooting, especially with manual focus, then the K-01 is a great choice. For that, the benefits of lovely photo quality definitely outweigh the other drawbacks.

But if you're looking for an all-purpose ILC under $1,000, you may get frustrated with the K-01's slow performance and large, quirky design, and it's probably worth trading off a little on the photo quality for a better all-around camera, and likely a less expensive one.
