Will an SLR Lens work with a DSLR Camera?

Question

I have an old Sigma lens that fits a 35mm Canon Rebel. Will this lens work with a DSLR Canon Rebel? If so, are there any limitations?

Answer 1

Yes but you will only be able to use manual focus and all auto metering functions will be inoperable.

Answer 2

As long as it is EF mount, it will work.

However, you will need to multiply 1.6x of the focal length to get the correct focal length, because Rebel's CCD sensor is not a Full size sensor.
