The Good Sharp, artifact-free photos in good light; somewhat improved high-ISO capability; excellent raw-processing software included; more than 40 available lenses; built-in dust shield.

The Bad Still largely limited to ISO 400 or lower; sluggish overall performance; subpar autofocus; inelegant design and ergonomics.

The Bottom Line Landscape, architectural, and other photographers who crave detail and sharpness should consider this digital SLR, but action and low-light shooters might want to pass.

Intro

Sigma's SD10 is the follow-up to the company's flawed but interesting SD9 digital SLR, which made exceptionally sharp photos in good light. The SD10 incorporates an upgraded Foveon X3 sensor, a three-layered imager with 3.4 million pixels and 10.3 million photodetectors. The new sensor partially overcomes the SD9's biggest weakness, which was its lack of high ISO sensitivities for low-light photography. But Sigma failed to correct most of the SD9's design and performance flaws, and the SD10 remains substantially less versatile and well rounded than competing dSLRs. The Sigma SD10's design is nearly identical to the SD9's, meaning that it's bulky, boxy, and homely. The 2-pound camera's metal chassis is surrounded by a black, polycarbonate body. Its size and squared-off shape make it a bit less pleasing to grip and handle than other dSLRs we've used.

Though its control placement is acceptable overall, and the menu system is clearly labeled and easy to navigate, our other objections to the SD9's design flaws still stand: the shutter-speed dial is hard to reach without taking your hand off the grip, and the skimpy viewfinder information display doesn't show the metering mode, the white-balance setting, or the number of shots remaining.

The SD10's feature set is mostly the same as the SD9's, but Sigma, or rather Foveon, did make one critical improvement: The camera's upgraded X3 sensor is now fitted with microlenses over its pixels, which increases its light-gathering power. That translates directly to the ability to set the camera's sensitivity as high as ISO 1,600. (The SD9 was limited to ISO 400.) The minimum sensitivity setting remains ISO 100. The microlenses also make longer exposures possible--as long as 30 seconds at all ISO settings.

The camera's exposure, white balance, and metering system is fairly comprehensive and includes all four standard exposure modes, custom white balance along with seven presets, and three light meters--eight-segment evaluative, center-weighted, and center spot. Exposure compensation to plus or minus 3EV now works in 1/3EV increments instead of the SD9's 1/2EV steps.

You can capture images only in raw format, so if you have a need for quick JPEGs, buy a different camera. The included Sigma Photo Pro 2.0 software--actually written by Foveon--is a powerful raw-processing application that makes reasonably quick and easy work of fine-tuning exposure, contrast, color balance, and color saturation. A nice new feature in version 2.0 is X3 Fill Light, which does a good job of brightening shadows without overexposing midtones and highlights.

Only Sigma SA-mount lenses are compatible with the SD10, but that's hardly a limitation. Sigma makes more than 40 different SA-mount lenses in focal lengths ranging from 8mm to 800mm. The size of the SD10's X3 sensor gives the camera a 1.7X lens-conversion factor, meaning that lenses used on the SD10 will capture the same field of view that a lens of 1.7 times greater focal length would capture on a 35mm camera. To combat the irritating problem of dust collecting on the sensor, which plagues many other dSLR cameras, the SD10 has a transparent protective cover just inside the lens mount.
