Combines the special effects advantages of 180° coverage with Nikon’s advanced D-type autofocus lens technology. Bright f/2.8 aperture for photographing in dim light or with fast shutter speeds. Full-aperture viewing and metering. Four 39mm filters bayonet onto the back of the lens. High-contrast images even at full aperture. Exceptionally lightweight for a fisheye lens. Built-in lens hood.
- Full-frame fisheye images with a picture angle of 180 degrees(diagonal)
- Close-Range Correction (CRC) system provides high performance at both near and far focusing distances
- Nikon Super Integrated Coating for minimized flare and ghost, providing good color balance
- Contrast is really impressive at f/2.8, pretty much as good as it gets.
- Sharpness. Wide open center sharpness is outstanding, corners are not though, not un till you hit f/8, you probably want to stop down to f/11 if you want absolute corner performance on it.
- Build quality.
- DOF/IR markings. Lens comes with both Depth Of Field markings and a Infrared compensation mark.
- IR performance. No hot-spot is detectable at any aperture, and pictures are sharp from f/2.8 and all the way out!
- Size. Small and compact.
- Ghosting/Flare, this lens handles this extremely well as long as the front element is kept extremely clean.
- CA, used in the worst of lighting conditions the lens can show some CA from f/2.8 to f/11. In most scenarios this will not show at all, not even on f/2.8
- Plastic Slip-on lens cap. I prefer the old one they had on the manual focus 16mm f/2.8 version. The plastic one doesn’t really sit that well at all.
- Vignetting/Light fall-off. On the D3 this lens shows a bit of vignetting wide open, and to f/5.6. It never bothered me to the extent that I don’t use it at f/2.8, both on film as well as on Digital. Vignetting in lenses comes down to taste, so I did not down rate the lens for vignetting.
