Also, for whatever it's worth, be aware that vintage lenses and other equipment that have been "identified" as desirable and useful are likely to only climb in price. For one thing, even if there are a bunch of them out there in the world, their numbers are finite. Not only are you
competing with a gazillion other filmmakers to collect them, but also, perhaps in some cases, with a gazillion-zillion still photographers and GWC's looking to pick them up. If you snooze, you lose. Within reason, of course. Not meant to encourage reckless spending.
As an example, as a neonate photography hobbyist (and I like to think
artist), I've been learning about the
Strobist Movement. It provides an interesting example of how new demand for vintage equipment drives the prices of such finite vintage equipment ever higher.
Best of luck with your T3i! It looks like a pretty awesome camera.
