if you buy a Canon consumer camera they normally come with a 18-55 lens, which is equivalent to the 28-80 in 35mm, almost for free.
That lens is quite useful IMHO and you may as well get it.

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
