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 short answer is: "None" See the answer for the question: Are canon t70 and canon eos rebel xsi lense compatible? The Canon AE1 takes FD mount lenses. All Canon digital cameras take EF lenses. They are not compatible.
Unfortuntely, No you can not use the AE1 Program lenses with Canon EOS cameras. They use different types of lenses, thus the diameter, connections and mount are different.
With just the standard lens? Maybe as much as $40 if it's in pristine shape. They can be had on eBay for $20.
