Pretty much Nilsen, since you're buying SLR lenses for it. There's an additional crop factor that actually increases the magnification on your digital SLR... so a 28mm lens would actually yield results similar to a 42mm (x1.5) lens on a regular 35mm camera. The higher the mm, the more the magnification. For taking pictures of birds, I use a 400mm lens. For taking pictures of the car at close range, I use a 10mm-22mm lens.
