Update mid-2012: the 20/3.5 Color Skopar shows very poor results on the Nikon D800 and can no longer be recommended.
New in April 2009, the ultra wide angle Cosina Voigtlander Color Skopar 20/3.5 SL ASPH is almost identical in size to its sibling 40/2 Ultron, though its LH-20 lens shade makes the lens slightly larger at the business end.
It offers a 94° angle of view on a full frame camera, and is extremely compact, excellent for those on the go, like hikers and/or backpackers. With the Voigtlander 20/3.5, 40/2, and 58/1.4, a very compact and flexible shooting kit is at hand for a wide range of applications from outdoors to portraiture.
