Just for a little clarification on probably the two most misused and misunderstood terms in photography.
Full Frame and crop factor.
Every camera is 'full frame' meaning you are going to get exactly what you see in your view finder or LCD screen. The term is meaningless to most amateurs as is, most likely, the crop factor.
But, now to the 'crop factor'.
A lens with a 100 mm focal length on a 1.6 crop factor body compared to the reference format of a 35mm film camera will yield the same field of view that a lens with a 160 mm focal length would show on that same format.
The focal length of the lens does not change by using a smaller sensor. The field of view is smaller because a smaller area of the image circle cast by the lens is used by the smaller sensor.
A 100 mm lens is and will remain a 100 mm lens no matter what body it is used on.

Hi ebiggs1,
Just a side note: I clearly understand your point, but don't completely agree. The "full frame" sensor cameras are those with a 35mm film equivalent size. The other types of cameras have different sensor sizes.
Of course you always get the full image from your camera' sensor, but the current nomenclature is aimed to make a clear difference between the cameras' sensor size to avoid confusion.
Canon itself calls "Full frame" to the DSLR with a 36x24mm sensor: "With supercharged EOS performance and stunning full frame, high-resolution image capture, the EOS 5D Mark III is designed to perform (..)"
The "universal" convention is to call "APS-C" cameras to those with an APS-C sensor (that may slightly vary between brands), and "Full Frame" cameras to those with a 36x24mm (35mm film equivalent) sensor size.
Regards
