We have a dog in some agility classes and I had noticed a lady taking awesome pictures with her Cannon and this lens; I was really impressed with the quality and the sharpness of pictures of moving dogs and would like to get one of these lenses for my Nikon D7200. Nikon lens is out of my price range and I was looking at Sigma and Tamron for better price point.
Does anyone has any experience with these. Is Nikon one really worth the 3500 mark??? Is Sigma better than Tamron??? Are there any other options for this kind of sports shooting???
Your options range from maybe a few hundred dollars used to $7000 new. Nikon has a f/2.8 and an f/4. Assuming the f/2.8 is out of budget range. an alternative to the AF-S Nikkor 70-200mmf/2.8 VR II:
Sigma 70-200/2.8 EX DG APO Macro HSM II is $950 (NEW)
AF-S Nikkor 70-200mm f/4G ED VR $1350 (NEW)
DXOmark.com rates both of these fairly high in your choices. If you’ve never used their site, you can select your camera and a variety of different lenses they have tested and see the results. Keep in mind, as you later replace the D7200 with better sensors, the performance of lenses become more important. When I upgraded from a D3s to a D850, the old nikon glass was no longer the king of the hill as far as sharpness, distortion, & aberrations. Buy as much lens as you can afford.
You spec out your need for a fast lens with less than top of the line cost. Between these 2, if you can afford the Nikkor, it is a better lens, but not as fast. Sharpeness is virtually identical. Where the Nikkor shines is in much less pronounced chromatic aberrations than the Sigma. Some of this may be able to be corrected out in Lightroom. If the extra stop is more important to you, go with the Sigma.
The DXOmark.com site lists performance for the more expensive lenses out of your range. If you can find one of these in good condition on the used marked you may want to evaluate that option as well. Also look at the refurbished Nikkor on Nikon’s site as well was at
