I've considered the 50-150mm, but because I also shoot film, this lens won't be of much use for me - and as a student, spending $900 on a single lens and only being able to use it on one camera is kind of illogical.
The 80-200mm crossed my mind, and I've seen plenty of people use it around my area, but I think if I'm going to go with a Nikon lens, I might as well get the 70-200mm for it's VR and especially HSM. The quiet and fast AF is what really gets me, and to get the most out of a fast telephoto zoom, I can see myself appreciating those two featres.
I guess I'll just save on the side for the next year until I can afford the 70-200mm Nikon. It will hold it's resale value, and I won't have any regrets about not buying the best lens.
The next problem I run into is pairing the lens. I won't want to pair it with the loud Sigma 24-70mm, and the Nikon is going to run me another $1900, as opposed to $700. Especially since I dream about the 14-24mm f2.8 hahaha.
Oh god, being a starving student really seems to have no plus side.
