I have the 70-300mm AF-S VR lens. It works fine and is small enough to carry around all day. I think this is a good lens to get started with shooting at the 300mm focal length range. It is f/5.6 at that end so you need good light, and you really want to be at f/8 or f/11 to maximize sharpness. However, today there is the new 70-300 DX AF-P VR lens and that is said to be a bit sharper at 300mm so you can use f/5.6 or f/6.3 with decent results. The price on this lens is below that of the above if buying new. The two 70-300mm models noted above offer faster AF than the 55-300mm lens and that is what you want for wildlife.
