The 300mm focal length has always been popular with professionals and advanced amateurs due to the combination of magnification, portability and close-focusing. 300mm is about the longest lens that can be hand held (in daytime lighting situations). The Nikkor 300mm f/4.5 Nikkor-H manual focus lens is a nice compromise in size and speed. Featuring a fixed tripod mounting bosses for each - vertical and horizontal formats and a built-in, telescoping lens hood, this lens is suitable for many outdoor applications.
This lens was originally a NON-AI model but it has been updated to work with later AI-coupled F-mount Nikon manual focus camera bodies.
