BTW Andrew...what's an 'APS-C'..???

It's the size of our sensors in all the Canon DSLR except the 5D the new 5D MkII and the Pro 1Dx series which is a Full Frame 35mm sensor.
The APS-C size is smaller which gives a cropped FOV in respect to the Full Frame sensor.

EDIT: yep what Dennis said, sorry posted at the same time.
