Did you know that you can save a ton of money and grow your video lens collection by buying old Canon FD lenses? You can find these for very cheap, I just saw a 50mm F/1.4 for under $100, that is a huge savings over the current Canon 50mm F/1.4 at around $400. The catch is that these old FD lenses require an adapter to use with your Digital SLR and they are manual focus only.
