Lens Description: 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. Introducing the AF-S NIKKOR 20mm f/1.8G ED, a compact, lightweight FX-format lens that combines the ultra-wide perspective of a 20mm focal length, the low-light capabilities and shallow depth of field of an f/1.8 maximum aperture and the superb optical characteristics of an advanced NIKKOR prime lens. Whether you shoot stills, HD video, time lapse sequences or star trail images on an FX- or DX-format D-SLR, the AF-S NIKKOR 20mm f/1.8G ED will widen your creative potential.

Photography Life Review Summary: For its $800 MSRP price tag, the Nikkor 20mm f/1.8G ED represents tremendous value. The lens has very quick and accurate autofocus and excellent center sharpness when compared to 24mm f/1.4 and 28mm f/1.8 lenses, especially at maximum aperture. It handles chromatic aberrations, distortion, ghosting and flare very well and does not suffer from focus shift and wavy field curvature problems that other lenses are known to exhibit. Although extreme corners do show signs of problematic handling of coma at f/1.8, stopping down to f/2.8 or cropping the frame a bit make this lens a great choice for astrophotography needs. The lens also seems to be a good candidate for infrared photography, though one has to be careful when using small apertures.

Whilst not a review, upon announcement by Nikon I intended to purchase this lens for landscape photography purposes. It is disappointing to see that Nikon has forgone weather & dust sealing on this lens. Does anyone know how much difference, and therefore protection is offered between those Nikon lens listed as weather and dust sealed, versus those that are not? Thanks in advance.
