I was going to say something earlier about that - its to do with how the size of your imaging sensor inside the camera affects the effective focal length of the lenses you are using. The sensors in film cameras (35mm) are larger than most digi's, which use a number of different size sensors. The sensors in Nikon bodies effectively cause a crop factor of 1.5. This means that a 300mm lens on our bodies behaves like a 450mm lens on a film camera

. This also means that an ultra wide 18mm lens is really only 27mm on our cameras

.

So when Ross was indicating what focal lengths he was using, you'd have to multiply them by 1.5 to get a camparison to your camera focal range (when expressed in 35mm terms).

But with your focal length range you're still covered.
