I have a Nikon d7100 which will accompany me on a trip west this fall. Much as I'd like to purchase a 70-200 lens, they all seem to be out of my price range which is around $500.00. I am thinkin of the 70-300 Nikon FX VR or Tamron di VC for landscapes and the occasional wildlife. Once I have additional money, I can upgrade.
Thoughts on either of these or the Sigma?
You will be disappointed when you use a 70-200mm lens on a crop sensor camera (D7100) for landscapes. Your widest field of view will be 23º. For landscapes you want a field of view of of 50º to 80º. You will be better off with an 18-300mm lens, using the low focal lengths for landscapes and the longer focal lengths for wildlife. However, even 300mm won't help if the wildlife is small or at a distance of 100yd or more. For that on your camera you will need a 500mm to 600mm reach mounted on a gimbal and a tripod.
You might want to consider renting if you can't find what you need for what you can afford.
