Nikon AF NIKKOR 16mm f/2.8 D Fisheye Autofocus Lens {Rear Bayonet}

Nikon's 16mm f/2.8D fisheye: full-frame, 180-degree autofocus coverage

The AF NIKKOR 16mm f/2.8D Fisheye is a full-frame circular fisheye that pulls in a 180-degree field of view at f/2.8, mounted to the well-proven Nikon F bayonet. As a D-type lens, it communicates distance information to compatible Nikon bodies, giving the camera's metering and flash systems data they can actually use. The rear bayonet filter attachment accepts a L1BC filter, which is how Nikon solved the physical impossibility of threading filters onto a bulging front element this wide.

At 16mm on a full-frame body, the image circle covers the entire sensor, producing the classic barrel-distorted fisheye frame than a vignetting circular image. The f/2.8 maximum aperture is genuinely useful for low-light fisheye work, where slower alternatives force you to push ISO or sacrifice shutter speed. This is a specialized optic with a specific visual language, and it executes that language with the mechanical reliability Nikon F-mount glass has built over decades of use.

Who It's For

Skatepark and action sports photographers who want extreme perspective distortion close to the subject will find the 16mm focal length and f/2.8 aperture suited to shooting in mixed or artificial light. Architectural photographers documenting tight interior spaces, vaulted ceilings, or narrow corridors get genuine full-frame coverage without cropping. Astrophotographers shooting wide star trails or aurora can use the 180-degree field of view to take in the full sky dome. Experimental portrait and street photographers drawn to the exaggerated spatial relationships this focal length creates have autofocus to work fast.

FAQ

Does this 16mm fisheye work on crop-sensor Nikon bodies?

Yes, it mounts to any Nikon F-bayonet body, but on DX sensors the effective focal length becomes roughly 24mm and you lose the full 180-degree circular fisheye effect.

How does the rear bayonet filter attachment work?

The L1BC filter screws into the rear bayonet mount inside the lens barrel, avoiding the physical problem of threading a filter onto the bulging front element.

What does D-type mean on this lens?

The D designation means the lens communicates distance information to your camera body, enabling better through-the-lens metering and flash exposure calculation.

Is f/2.8 fast enough for handheld low-light fisheye work?

Yes. At f/2.8 you can shoot at reasonable shutter speeds in dim conditions without excessive ISO, which matters more for fisheye than faster primes since you're covering extreme wide angle.

Will this produce a circular vignette or fill the full frame?

On full-frame bodies, the 16mm image circle covers the entire sensor, giving you the full rectangular frame with barrel distortion, not a circular fisheye image.

Does autofocus actually work well with such an extreme focal length?

Autofocus functions, but depth of field is massive at 16mm fisheye, so manual focus is equally practical and sometimes preferable for precise composition.

What's the optical formula-how many elements?
