Ultra-thin Nikon pancake at 45mm with P-type CPU, the most compact F-mount lens with electronic metering compatibility.
The Nikon Nikkor 45mm f/2.8P is an ultra-thin pancake lens for the Nikon F-mount, designed as a special edition lens that transforms Nikon SLR and DSLR bodies into the most compact possible setups. The P designation indicates a built-in CPU for electronic communication with modern Nikon bodies including matrix metering.
The 45mm focal length provides a slightly wider-than-standard perspective, and the ultra-thin pancake design keeps the lens barely visible on the camera body. The P-type CPU enables full matrix metering and program exposure on modern Nikon bodies — a significant advantage over non-CPU manual focus lenses.
Build quality uses a minimal barrel design to achieve the thinnest possible profile. The lens has no focusing ring — focusing is achieved by rotating the entire front element assembly. The ultra-compact dimensions create the most portable Nikon F-mount kit possible.
The Nikkor 45mm f/2.8P is a special-edition lens that commands premium prices on the used market due to its unique pancake design and limited production. The P-type CPU and ultra-thin profile make it the definitive compact lens for Nikon F-mount photographers who prioritise minimum size.
