I have a D7000 and am considering purchasing an ultra wide angle zoom lens, particularly for landscapes and for indoor use such as shooting in churches when traveling in Italy, or in museums. I am considering the Tokina 11-16, F/2.8 and the Nikon 10-24. I have Nikkor 18-105, 35, 50, and 105 mm lenses the primes being fast lenses. WIll I benefit from the faster lens indoors - in the buildings, churches, museums I visit or would the strengths of the Nikon (reach, color) outweigh its poorer aperture? ANy advice, opinions will be appreciated. Thanks
