This compact ultra wide angle lens from Nikon costs around ￡680 and sports a bright f/1.8 maximum aperture, silent, internal focusing with full time manual focus override and Nikon's Nano Crystal optical coating, to improve contrast while suppressing ghosting and flare.

Very sharp when stopped down; Relatively compact and lightweight; Silent focusing; Low distortion for an ultra-wide angle lens; Good value; Nano-Crystal optical coatings

Falloff of illumination is quite severe at max aperture; Could be sharper at maximum aperture

This must be the best I have ever bought, it is not too heavy, unlike my trinity of zooms. The sharpness is breathtaking from corner to cornet. The distortion is minimal and the colours and contrast are perfect for me. Incredible

Sharp at all apertures; lightweight; low distortion for the Focal Length

None

Finally Nikon have an ultrawide angle lens with a fast aperture of F1.8. It also has the amazing VR which means you can handhold this lens at ridiculously slow shutter speeds. This means it is perfect interiors, architecture and landscapes where you do not have a tripod.

The Nikon AF-S Nikkor 20mm f/1.8G ED is a high-quality, compact and relatively affordable wide-angle lens for full-frame Nikon DSLR users, although it lacks any form of weather-sealing and optical image stabilisation.

As optical design and construction improved, Nikon was able to introduce a more conventional Nikkor 20mm f/3.5 lens in 1967, and in 1989 the first Nikkor 20mm f/2.8 autofocus lens appeared.

What a cracker of a lens. Beautiful color rendition and sharp end to end

"I am shooting with a Nikon D810 full frame. I wanted a lighter lens by Nikkor with a wider angle of view. So I did my research and traded in Sigma 35 mm F/1.4 for this Nikkor 20 mm F/1.8. The new 24 mm F/1.8 is still too new and rare to see if it's any good.

With the ultra-wide view of a 20mm lens, you're free to capture expansive landscapes and architecture, wedding parties, an entire band on stage, crowd shots and much more. Add low-light capabilities to that view, and the shooting possibilities are nearly endless.

I think the other reviewers are missing the point with build... This is designed to be ultra lightweight, and I am actually very happy with that. It is actually annoying sometimes carrying around very heavy lenses: when you put an f/1.4 lens on your camera you can more than double the added weight...

Consistent Output; Durable; Easily Interchangeable; Lightweight; Quick Focus; Sharp Focus; Strong Construction
