It has a fiercely loyal base of support and some rather vocal detractors. Commonly cited advantages and disadvantages of the camera include the following: Pro Excellent color in daylight and good light. Excellent detail, comparable to 6.5 MP Bayer-sensor DSLR cameras. Noise-free image of the at low ISO speeds Pixel sharpness achievable Moiré effects less visible when photographing high-detail patterns compared to Bayer senor based cameras; thus no need for sharpness-degrading antialiasing filters to reduce moiré effects High-quality PC software allows images to be tuned easily to the best quality Takes easily obtained AA or CR-V3 batteries instead of proprietary format Dust protector stops dust entering the mirror box while changing lenses Sports finder allows viewing area outside picture area, letting photographer see if a better composition could be made by zooming out Inexpensive when it can still be found Shooting-priority user interface means always ready to shoot Unique histogram feature shows distribution of RGB values in zoomed-in area of image Simple and intuitive menu system Mirror lock up on dial Removing the dust protector converts the SD10 into an infrared-sensitive camera Con Does not produce JPEG files in-camera Fewer photographs per image card because no JPEG mode available. Raw files are compressed to about 8 MB per image Slow to clear the shot buffer Originally expensive, listing at $1599 in U.S. Only takes Sigma lenses; no third party support except via adapters Poor low-light performance; high-ISO modes produce noisier images Image quality degrades in long exposures (over 4 seconds) No built-in flash Single autofocus sensor instead of three or more in competition References External links Official Sigma SD 10 Page Official Sigma SD10 Page (outdated) Official Sigma SD10 FAQ (outdated) Foveon.com, the maker of the X3 sensor used in the SD10 DPReview.com Reviews the SD10 SD10 user image galleries Sigma SLR Talk Forum on dpreview.com CNET Specs SD10 Manual in PDF SD10 Cameras introduced in 2003
