Nikon Nikkor 50mm f/1.2 AI Lens – Ultra-Fast Manual Prime – Superb Optics

Description:
The Nikon Nikkor 50mm f/1.2 AI is one of the fastest lenses Nikon has ever produced—a manual focus prime with an ultra-wide f/1.2 aperture that delivers stunning low-light performance and beautifully shallow depth of field. Introduced in the late 1970s, this lens remains a favourite among portrait photographers, collectors, and vintage lens enthusiasts.
