The focal length of the lens whether it is on a full frame or smaller sensor camera remains the same. So 50mm is still 50mm. 100mm is still 100mm.
The field of view or area that lies within the borders of the photo frame is effected by a small sensor 'cropping' it, as if you cut a section out of the middle of a full frame photo. If you have a 1.6 crop, then 1.6x is the difference between a full frame field of view and a crop sensor field of view.
If one photographer has a full frame camera and the other a crop sensor camera and they stand side by side taking a photo, a full body shot of a man for the full frame photographer would look different for the crop sensor photographer who might just see the man's head and shoulders. If you are not comparing one camera to the other camera it shouldn't make a difference, you will stand where you need to in order to create the proper composition or in this case get the entire person in frame. The viewfinder or liveview on your lcd gives you an accurate enough perspective of what will be in frame. There should be no surprises.
There are benefits to crop sensors, such as in macro photography when it is one's intent to get closer. You can do so without physically changing the size of the image via software cropping, where as if you were full framed you might want or need to crop to enhance, say, the center of a flower making it appear larger. Crop sensors might not be as favorable in sports photography or journalism and yet, you learn to work with what you have to get the shot you want in frame.
Regarding lenses, if a fish-eye lens designed for a full frame camera is put on a full frame camera the result is 'intentional' barrel distortion. You know the classic rounded panorama shot-- though some fish-eye lenses are less distorted. However if the same lens is put on a crop sensor camera the distortion isn't as emphasized. Again this is due to the crop. Your camera will be cropping out the outer edge of the photo frame that is most distorted by the fish-eye lens. Some mfg's make special crop sensor fish-eyes for this reason. Crop sensors do not add distortion to lenses so even if you have a lesser quality lens with some distortion on the edges, the crop sensor camera will take from the center where the image is more sharp and without distortion.
Every once in a while there is a photographer/blogger or writer, that shares this info and it is clear but most of the time you hear.. "Oh that 50mm is like 80 mm on a crop body." It's basically a lazy way of stating something that would be better explained in full, which would take only a few more words really. But it is what it is.
Depth of Field.. =D
