You can use them on any Canon digital SLR but there is one catch. Unless you get a DSLR with a full frame sensor, there is a crop factor. Why?? The others have a smaller sensor. To help photographers that tend to think in 35mm the crop factor is a number that you can multiply by the lens focal length to compensate for that smaller sensor. For most Canons that number is 1.6. So if you put a 400 mm lens on a DSLR with a 1.6 crop factor 400*1.6=640 or it would give the 35mm equivalent of a 640mm lens. Bird photographers like that, but it works against you at the other end. That 28mm lens isn't so wide anymore. 28*1.6=44.8 or about what you would get with a 50 mm lens on a 35mm camera.
The good news is instead of needing to buy all new lenses, if you get the smaller frame sensor you may need to buy just a wide angle lens to compensate. They make some really wide angles just for that purpose. Depends on what you like to photograph, and how big the budget. A camera with a full frame sensor is going to be much more expensive than a smaller APS sized sensor. Like most things, there is always a trade off.

For sure you can use them with the Canon 5D and 5D Mark 2 and get the exact focal length equivalent as these bodies house full frame sensors.Additionally they would work with the 20, 30, 40, 50, 70 D series of digital bodies but a 1.6 crop factor due to a smaller sensor size will be applied which essentially lengthens the focal length of your lenses.Happy shopping.Lea
the most wonderful things in life aren't thingsDear Group: I have a Canon EOS Elan 35mm SLR- I have Tamron lenses that I use with this camera - love them
28-200mm zoom 72mm lens; 200-400mm zoom 75mm lens and 90mm F/28 macro 1:1 lens
Does anyone know if there is a Canon digital camera that will allow me to use these lenses? I really didn't want to have to buy digital lenses.
Thanks so much.
Barbara
