    Nikon AF-S 300 f4 vs sigma 120-300 f2.8 NO os

    While the Sigma is for sure a great lens optically thanks to its f/2.8 aperture I would suggest to look at another aspect which is minimum focal distance. The sigma can focus only from 2.5m at 300mm. The Nikon can do 1.5m. That could make a huge difference when shooting small birds.
