Description:

The Nippon Kogaku Nikkor-H Auto 50mm f/2 is a classic manual focus lens from Nikon’s early pre-Ai (non-Ai) era, produced in the late 1960s to early 1970s. The “H” in the name stands for "Hexa", referencing the 6-element optical design, and “Auto” refers to its automatic diaphragm stop-down feature (not autofocus).

Despite its age, this lens is beloved for its solid metal construction, smooth manual focus, and characterful rendering—producing images with a vintage feel, slightly lower contrast, and natural-looking bokeh. It’s an excellent choice for film shooters and digital users (with the appropriate adapter or camera compatibility) looking for classic Nikon glass with a timeless 50mm focal length.

Please note that as a non-Ai lens, it may not be compatible with all modern Nikon DSLR bodies without risk of damage. However, it works well with mirrorless systems via adapter and is often used for its unique optical signature.
