I need some suggestions for adding a lens to fill a gap I have before my JUly/AUgust vacation. In late July my wife and I will be spemding 10 days in Spain followed by a 7 day Western Med cruise. The stay in Spain will be be 2 days in Barcelona, 7 days in Marbella (Malaga),1-1/2 days in Madrid followed by the crusie with stops in Naples, Rome, Florence, Marseille, France, and Palma, Spain, before returing to Barcelona.
My body is a D7000 and the current lenes are a Tokina 12-24mm f/4, Nikon 50mm 1/8G, Nikon 70-300 AF-S VR, and a Sigma 150-500. I have an obvious gap below the 70-300. I'd like to minimize the amount of of gear that I'm taking with and really can't see the need to take the Sigma150-500, but I'm struggleing to decide what to add. I've been considering a Nikon 18-105, or either Tamron 17-270 or Sigma 18-250. The Nikon18-300 is just not in the budget, although a used Nikon 18-200 would probably fit it. I've also thought about a Sigma 18-50f2/8, but I think that will still leave me with too much of a gap.
Any thoughts or suggestions would really be appreciated.
