I have a Nikon D700 with a Nikkor 50mm f1.8AFD, an 18-55mm kit lens and a Sigma 70-300mm f4-5.6 APO.

However I recently went on a business trip to India and as luggage space was limited I only took one lens, the 18-55mm, however I found the zoom range a bit restrictive, so I'm currently thinking about purchasing either an 18 to 105mm or 18 to 200mm zoom for use as a general zoom.

Any suggestions would of course be most welcome
