Nikon released the first NIKKOR lens, the NIKKOR-S Auto 5cm f/2 in 1959, along with Nikon’s first digital SLR camera, the Nikon F. In the fifty years since the launch, NIKKOR lenses have been extremely well received by a great number of photo enthusiasts and professional photographers.

Nikon’s current product line-up includes more than sixty NIKKOR lenses for Nikon SLR cameras, from fisheye lenses, super wide-angle to super telephoto lenses and micro lenses.
