I sweated for a while before buying this lens, because I was worried 20mm would be too limiting. Too wide or too this or too that, but... it isn't. The 20mm 1.8 is now finding its way onto my D610 at almost every shoot, and the results are fantastic.

Its lightweight ...compact in size...pretty quick to focus and its sharp. I really like how the glass renders the images, color and contrast are very nice. Little to no distortion as well. I wanted to go with the ultra-wide zooms but...if you want to use a ND filter set..

I love the 20mm f1.8 lens. It's sharp. The ultra-wide lens is perfect! I shot low light desert scenery as well as rows of brown-stones and city buildings in Chicago at night. The lens performed perfectly. The bokeh is perfect. I highly recommend this lens.

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

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.

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...

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.

optically excellent, light weight for its size, easy to travel with, and well suited for hand held low light situations. The two attached photos were taken hand held at night with an aperture of f/1.8, shutter speeds of 1/100 and 1/125, and ISO levels of 1250 and 3200 pic 1 & pic 2 or here

Perfect for astrophotography and landscapes. This lens is almost always in my bag. I would have to replace it if lost or damaged. I use it on both FX and DX.
