I'm no expert, but I believe this means the aperture is open to the widest it goes (lowest f/#).
Example: If you are shooting with a 70-200mm f/2.8, using an aperture of 2.8 would be "wide open", whereas an aperture of f/5.6 would be considered "stopped down."
I'm not positive, but I don't think focal length (the zoom) of the lens has anything to do with it.![]()
You are correct.
I didn't think you could zoom/crop the image in camera. 
to a D90. Problem is, that he will still have my zoom, and I will need one myself.
I'm sorry about that, it does make a bit of difference in my post, eh?
