Old Canon Lenses Digital
Is there a way to use film lenses on a digital SLR camera?

I recently got a digital SLR camera (Canon Rebel XT) and my Dad has several good lenses for greater film-based SLR camera. The lenses are different in the fact that the old have 3 "blade" pieces metal type at the bottom instead of the new lens relatively flat. Is there anything I can get to use older lenses on my new camera? I really want to use that lens Thanks guys, will do little more than an investigation and see if there is an adapter available.

First, determine what brand of camera his father lenses were made for. If a Canon FD mount type (FTB, AE-1) then an adapter is required. If the lenses are of a Minolta MC / MD mount (SRT-202, XG-9 XE-7, X-700), then you will need an adapter. This adapter can often be found on eBay. If the lenses were for a Nikon is an adapter for use in your Canon DSLR. Although There are adapters that allow the use of non-Canon EOS mount, there are limitations that must be considered. 1) Some of the lenses can not focus to infinity. 2) All those using an adapter must be focused manually. 3) All lenses require the use of "stop down" metering. What this means is that since no mechanical or electrical connection between the camera and lens aperture stays where you set it. If you're shooting very open (f1.4, 1.7) this is not one problem – the display is bright. However, if you stop down for more depth of field (F5.6, f8, etc) the display goes dark – making it difficult if not impossible, approach. So you focus wide open and then stop until the opening you want, metro and take the picture.
