Digital Cameras Photo Reviews of Sigma 20mm f/1.8 EX DG RF Aspherical Wide Angle Lens for Pentax and Samsung SLR Cameras
Customer Review: Best Indoor Lens for Your Pentax SLR !
Summary: 5 Stars
If you want to take indoor shots with your SLR, this lens will let in enough light to stop the action. It also will work on your film camera for those REALLY wide-angle shots. I typically use prime lenses for shooting indoor shots and this is one of the best, because of the wide angle (30mm equivalent), sharpness, and speed. No other wide lens has the speed of this one (f1.8). I have taken shots in DIM light without flash that have come out great. My best 3 lenses for indoors are this one, a Pentax 35mm F2.0, and a Pentax 50mm F1.4. I have a Sigma 28mm F1.8, but it is not as sharp or useful as this one. The only drawbacks are the size and the cost of a filter that fits this (82mm filters are NOT cheap).

Description of Sigma 20mm f/1.8 EX DG RF Aspherical Wide Angle Lens for Pentax and Samsung SLR Cameras
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.Lenses
