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.
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 Canon AE1 lens will not fit a Canon digital. You can buy an adapter that will allow the lens to work in manual focus mode on the digital camera.
The 2x Digital Telephoto Professional Series Lens fits kodak easyshare.
ED has nothing to do with the camera mount; it is a lens (glass) quality so yes, it will fit
yes
In short, yes. More specifically, as long your zoom lens is an "EF" mount lens, it will work with all Canon Digital-SLR models from the EOS line. You can determine if a lens is an EF mount from the full name of the lens. The full name of the lens is usually written on the outside of the len itself.
not without a converter. but then it becomes a completely manual lens. focus, meter, everything.
If it is an autofocus lens then it will fit on current Canon bodies, assuming it is a Canon mount lens. For older lenses they may work with an adaptor but some metering functions may be lost.
Digital SLR referes to "digital single-lens reflex." This terminology is often used when speaking about cameras. Such cameras can allow the photographer to change lenses as he or she sees fit.
NO. The lenses are designed for a specific brand name camera. A lens for a Canon camera will only fit a Canon etc.
Yes as long as it's not pre AI
