If a camera lens has the letters USM printed on it, it means UltraSonic Motor. This means that the motor is built into the body. These lenses tend to cost a little more than a lens without a USM.

Sigma builds lenses with mounts to fit Sigma and other cameras. I own two which are made to fit a Canon body. These would not work on a Sigma camera as they are, but I'm sure the lenses are also available with a Sigma compatible mount. This involves the type of locking ring as well as the location and number of electrical contacts for the motor. So when buying a lens, make sure it has the mounting configuration for the camera you own. The specs should say "for Sigma" or "Sigma mount", etc. I have tele-converters made by both Canon and Sigma. The mounts look the same, but if I recall correctly I can't use my Sigma converters with certain Canon lenses. In some cases, the equipment may fit, but the combination is not guaranteed to auto-focus. Or the focal length of the lens plus converter may be mis-reported in the EXIF information. Check compatibility tables. Without a converter you shouldn't run into many problems. But before investing a lot of money, It helps to locate a shop that carries the lens in question and try it on your camera.
Yes, the sigma is a good lens for the money. One cannot expect professional result with this chepo lens but for an enthusiast it will serve the purpose.
Canon EF lens mount was introduced in 1987. It is the standard lens for Canon EOS family of SLR films and digital cameras. The EF or Electronic Focus is handled by a dedicated electronic motor which is built into the lens.
Sigma lenses are designed to fit specific camera mounts, which means they will not fit all digital SLRs universally. Each lens model corresponds to particular mounts, such as Canon, Nikon, or Sony. However, if you have a compatible Sigma lens for your camera's mount, it should fit and function properly. Always check the lens specifications and your camera's mount type to ensure compatibility.
Yes, a Sigma 10-20mm lens can fit a Nikon D100, provided you have the version of the lens designed for Nikon mounts. The D100 uses the Nikon F-mount, which is compatible with many Sigma lenses designed for Nikon cameras. Just ensure the lens is in good condition and compatible with the D100's autofocus system, as the D100 is an older model.
The Sigma USB Dock is compatible with Canon cameras that have a Canon EF lens mount.
