Verdict

Due to its ultra-large max. aperture the Sigma AF 20mm f/1.8 EX is very ambitious lens. In theory you may argue that lens may be used for low light photography but its performance at max. aperture isn't really good enough for this. However, thanks to the very reduced depth-of-field you can exploit some creative potential at f/1.8 by blurring the surroundings of an object (see e.g. the flower pot sample shot above). At a more conventional aperture setting of f/2.8 the lens is already capable to deliver decent results and at medium apertures it is even excellent. Besides being faster the lens is slightly, sometimes even substantially cheaper than genuine manufacturer 20mm lenses so it can give you lots of bangs for your bucks ... assuming a good sample that is.
