The original review of the Nikon 300mm f/4D AF-S lens was published back in 2009 and was very short. I decided to completely rewrite it, with all the latest information, MTF data, more feedback and sample images, so you are looking at an updated version. If you are a birder, you have only two budget choices for Nikon – either the Nikon 300mm f/4D IF-ED AF-S or the much more expensive Nikon 80-400mm VR that was introduced in 2013. All other semi-professional lenses by Nikon are not good enough/long enough for birding. The old 80-400mm f/4.5-5.6D VR was too slow to focus and a lot of people including myself expressed their frustration with it for fast moving birds. I have been using the Nikon 300mm f/4D lens for over 6 years now and have been very pleased with the results. I take it with me everywhere I go and have used it more than any other telephoto lens so far. It is relatively light and I primarily use it handheld for shooting birds and other wildlife of Colorado.
In this review, I will go over my thoughts on the Nikon 300mm f/4 AF-S lens, provide sample images and compare it to other telephoto lenses like the new Nikon 80-400mm VR, Nikon 200-400mm f/4G VR and Nikon 70-300mm VR.
