A 135mm lens on the D/DS bodies provides a field of view equivalent to a 200mm lens on a 35mm film body.
That said I like to consider constant f/4 as being consumer and constant f/2.8 as being semi-pro/pro ;) I know, more like wishful thinking :D
The faster long lenses are certainly targeted to professional use, due to their price primarily. But I tend to prefer the slower long lenses as they are much lighter and smaller. I really don't need a 300mm f/2.8 lens, regardless of whether I consider it "pro" or "consumer". It's too much to carry.
