Nikon 1's ultra-compact pancake — the 10mm f/2.8 for the discontinued 1-system.
The Nikon 1 Nikkor 10mm f/2.8 is a pancake prime designed for the Nikon 1 CX-format mirrorless system, providing a 27mm full-frame equivalent field of view on the 2.7x crop sensor. It was one of the first lenses released alongside the Nikon 1 system and became the canonical compact walk-around option for J and V series bodies.
The lens delivers 10mm (27mm equivalent on CX) at f/2.8 maximum aperture in an ultra-compact pancake form, with Nikon 1 electronic coupling for autofocus via contrast-detect AF, and CX-format-only image circle. Build quality is plastic with a compact mount footprint matching the slim CX body dimensions.
Paired with a Nikon 1 J or V body, the 10mm f/2.8 creates one of the most genuinely pocketable interchangeable-lens camera combinations of its era. The 27mm equivalent provides a natural wide-normal perspective. The Nikon 1 system was discontinued, making this lens available only on the used market.
Test autofocus speed and accuracy on a Nikon 1 body — the contrast-detect system varies in performance by body generation. Check the aperture blades for clean operation. Inspect the mount for secure, wobble-free attachment. Note system discontinuation limits repair support.
