Like most higher-end DSLRs, the SD1 has two control wheels. One is embedded vertically behind the shutter button, and the other is atop the camera positioned as a dial to be turned with your thumb. Buttons abound to control exposure compensation, metering, ISO, and AF. Meanwhile, there's also a button to access the quick menus. The SD1 makes even better use of its buttons with a pair of quick menus instead of just one. You can move between the two with the control wheels, while the four directional buttons ont he camera back switch between letting you access AF drive mode, flash mode, ISO, and metering; or color mode, file type, white balance, and image quality settings. We're surprised that no one has done something like this yet.
