Description — Nikon 50mm f/2
The Nikon Nikkor AI 50mm f/2 is a prime lens designed for the Nikon F mount, with a full-frame image circle and a 50mm focal length that places it firmly in the standard range. The f/2 maximum aperture delivers a useful degree of background separation and performs well when light levels drop. Weighing just 230g, it is a pleasantly compact companion for Nikon F-mount DSLR shooters who want a lightweight standard prime.
The 52mm filter thread keeps accessory compatibility broad and affordable. Focusing is entirely manual, which rewards photographers who enjoy a deliberate, tactile shooting style. There is no image stabilization, so steady technique or adequate shutter speeds are important for sharp results handheld.
For shooters already invested in the Nikon F ecosystem who want a capable, lightweight standard prime under their own focus control, this lens is a straightforward and practical choice.
