they are a good lens for my Nikon D40?
I like to buy a lens, and there are 2 options in my mind now that he's Tamron 55-200mm F/4-5.6 Di II LD and Sigma 55-200mm/4.0-5.6 DC. well, I would like to know what is best for my D40 and 2 lenses have built-in motor?
I agree with this. If you spend a little more for the Nikon lenses will not regret I have only a 3rd party lens and is the Tokina ATX 80-400. that's a good lens, but still I wonder if I had saved the Nikon version I've been better. I have Nikon lenses still use the 70
