Nikon Nikkor-S Auto 50mm f1.4 AI Converted Prime Lens Cleaned Excellent

The Nikon Nikkor-S Auto 50mm f/1.4 is a classic, high-performance manual focus standard prime lens featuring an upgraded AI (Auto Indexing) conversion. Built with heavy-duty, all-metal Japanese precision, it features a fast f/1.4 maximum aperture for shallow depth of field, pleasing background bokeh, and impressive low-light shooting performance. Featuring the iconic scalloped metal focus ring and multi-coated optical construction, this camera lens has been professionally cleaned and serviced, making it fully ready for modern Nikon AI-compatible film SLRs (such as the FE, FM, F3, and FE2), late digital SLRs, or for adapting to modern mirrorless digital systems.

The Nikkor-S Auto 50mm f/1.4 was Nikon's flagship standard high-speed prime throughout the 1960s and 70s. While original Non-AI versions cannot be safely mounted on modern Nikon DSLRs or many late film bodies, this professionally cleaned and AI-converted example offers vintage optical character with full mounting versatility across classic and contemporary camera setups.
