Is there a multipier for older AF lenses on new digital came

[dataBoy]

In other words I know the AF-S 18-55 has a multiplier of 1.5 to think of it in terms of 35mm lense so it is 28-82 35mm equivelent. But if I use an AF lense for a film camera, say a 50mm is it then like usinga 75mm? Hope this makes sense

Simple answer is "yes". What happens is the sensor is smaller than the film, so it "crops" what the lens can actually see, effectively giving a more telephoto (or more zoomed-in) view. So that 50mm will be effectively a 75mm on Nikon's current DSLRs, even though the lens was designed for film.
