"Crop 'body'" is more about the sensor size. Without complicating things, basically the T#i series of Canons have a sensor that is smaller than a "full frame" sensor. As such due to physics and optics and all that fun stuff, the "zoom" factor on a crop sensor (at least, this one in particular) is about 1.6. Meaning that a 100mm lens on this crop sensor is roughly equivalent to a 160mm lens on a full frame. Since crop sensors are smaller, they do typically make the bodies a bit smaller, but the terminology is more about the sensor than the body.ah, i get it! "crop body" actually refers to the size of the camera body! gotcha! :
Basically, you can visualize an image taken with a full frame camera, and cropping a portion out of it, and that's roughly the result that you get on a crop sensor.
It's not all that important to know the differences between the full frame and crop, only that a) they exist and b) that you have a handle on the relative differences in focal lengths between your own lenses on your own body/sensor. There are some other things (e.g. "Normal" lenses - which relate to how your eyes see the world vs an SLR lens and stuff like that), but they're really not anything to worry about just yet.
