Sigma Wide Angle 20mm f/1.8 EX DG Aspherical Autofocus Lens for Pentax AF
( Focal Length: 20mm )
This super-wide-angle lens is ensured minimal light-fall-off with superior peripheral brightness. The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background. This is an ideal DG lens optimized Digital SLR camera. Minimum focus distance The minimum focusing distance of this lens is 20cm (7.9 inch) and it has maximum magnification of 1:4 with fast F 1.8 maximum aperture. The minimum focusing distance of 20cm (7.9 inch) and 94.5 angle of view allow close up photography surrounding the photographic subject. Handling The lens incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The rear focus system eliminates the need for the front of the lens to rotate, thus allowing the use of a Petal-type hood, which is superior light blocking effect. Incorporated aspherical lenses The use of aspherical lens elements in both of the front and rear lens groups effectively compensates for distortion, spherical aberration and astigmatism.&ref=Become

Sigma 20 mm for Astrophotography
...I purchased the Sigma 20mm f/1.8 lens, mainly for wide field astrophotography purposes. I refuse to pay what Canon was asking for a comparable lens...this Sigma lens costs less than half of what ... read more

review from Amazon User
Pros & Cons :that's a clever design and is nice if you do a lot of switching between manual and autofocus, because you don't have to look at the lens to find the little switch like you do on most lenses.
very nice lens
...I use the lens on both a Nikon d300 and a Nikon d700. I was pleasantly surprised to see that the lens is quite sharp wide open, at f/1.8. Stopped down to f/4 or f/5.6, the lens is very sharp, at ... read more

...Flare control, contrast and color rendition are fine. Bokeh and macro performance are surprisingly good for a wide angle. All in all, I'm glad I didn't spend a lot more (in these tough times) to ... read more

review from Amazon User
Pros & Cons :if i had to decide again, i'd probably opt for the 24mm or possibly even the 28mm - the effective focal lengths would be a little more practical for my purposes.
...Optically, I was disappointed at first, because I was getting soft pictures when it's wide open, even when on a tripod. But then I did a focus test and found my camera was back-focusing. I have a ... read more
