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.
The SD10 has no built-in flash, but the camera's hotshoe will accept powerful external flashes, including two Sigma TTL-dedicated strobes. Flash-sync speed is a decent 1/180 second.
Like the SD9 before it, the Sigma SD10 offers adequate performance but still lags a step or two behind the competition. Shutter delay varies from about 0.3 second to 1.5 seconds with autofocus, and it's about 0.2 second with manual focus. Shot-to-shot time is slightly more than a second. In continuous-shooting mode, the camera fires at 2.2 frames per second for a six-shot burst, after which a 7-second buffer stall sets in. These figures range from mediocre to poor for a dSLR.
