Thanks Brian. She only got interested in photography a year or two back and is completely attached to zooms, so I don;t think we will go fixed. We have a few trips in mind - Costa Rica this winter and (hopefully) Namibia next year, so zooms (and no lens changes) tend to work best. She'll have two bodies - D7000 and D3100 (unless we upgrade that). Thought about a D600 but I don;t see the point at that price. Anyway, thanks for the suggestions. d.
