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 for Nikon's discontinued 1 system, providing a 27mm equivalent wide-angle. At only 22mm thick, it is one of the most compact interchangeable lenses ever produced. The f/2.8 speed and AF make it practical for everyday use on the tiny 1-series bodies.
Sharpness is good for the 1-inch sensor. The 27mm equivalent is useful for everyday and street photography. The pancake format creates one of the most pocketable ILC setups in camera history when paired with a J-series body. AF is functional. No weather sealing. The ultra-thin profile is the defining feature.
Nikon 1 mount — discontinued. Filter thread is 40.5mm — tiny. Weight is approximately 77 grams — negligible. Build quality is basic but functional. The ultra-thin design — thinner than a body cap — creates a truly pocketable camera system. The 1 mount is discontinued with no future.
Very cheap. Check AF. The most compact ILC setup possible when paired with a 1-series body. The discontinued system limits future utility. Only for existing 1-system owners or those wanting the absolute minimum camera system size.
