Comments about Sigma Sigma 20mm f/1.8 EX Aspherical DG DF RF AutoFocus Super Wide Angle Lens with Hood for Nikon AF D Cameras:
This lens is one of "the thousand eyes" which the night has. (Thank you Bobby Vee or Vinton or whomever). It captures the emotion we all feel while experiencing cityscape or the "Starry, Starry Sky". (Thank you Elton John?) Need I say, broadens one's horisons?

Comments about Sigma Sigma 20mm f/1.8 EX Aspherical DG DF RF AutoFocus Super Wide Angle Lens with Hood for Nikon AF D Cameras:
This lens is much maligned on listservs because of supposedly poor performance wide open. At 1.8, however, it is the only 20mm lens of this speed available. While it is a bit soft wide open, it is fine for my purposes. However, stopped down only to f2 or f2.2 my sample becomes extremely sharp. The minimum focus distance is also extremely close, providing near-macro, wide field capability.

Comments about Sigma Sigma 20mm f/1.8 EX Aspherical DG DF RF AutoFocus Super Wide Angle Lens with Hood for Nikon AF D Cameras:
This is another Sigma fast wide angle prime. I also own the 30mm and 50mm f1.4 and this has a very pleasing bokeh as well as just the right sharpness for portraits. I think the sharpness at 1.8, while not the razor sharp you'd want for a macro, is just the right sharpness for people. It is large and heavy and requires an 82mm filter but I don't consider those shortfalls, just artifacts of the design.
A nice feature is that it focuses down to 6.5" which is great for getting those in your face non-flattering shots :)
It doesn't have HSM but it focuses nice and fast on my D90.
I have never experienced focus problems with any of my six sigma lenses and would not hesitate to buy Sigma again.

BARGAIN PRICE FOR A HIGH QUALITY FAST LENS. MANUAL ADJUSTMENT GETS THE MOST OUT OF IT.

Comments about Sigma Sigma 20mm f/1.8 EX Aspherical DG DF RF AutoFocus Super Wide Angle Lens with Hood for Nikon AF D Cameras:
Very fast lens and great depth of field for wide angle photography purposes. With a digital 1.5x factor, it makes for a great photojournalism lens.
