We recently shot a little comedy based around a local radio station. It's called Mixed Signals. We used the 550d with a 50mm 1.4 and 17-50mm 2.8.
Here's a little promo type thing we cut for the actors to check out while we're in post on the film.
We also wrote a short called INVISIBLE BULLETS that was shot by a friend of ours on a 550d using just the kit lens.

We'd love to hear your thoughts.
