The Sigma 50-100mm F/1.8 DC HSM Art is an interesting proposition. It's almost like three or four prime lenses in one (50mm, 60mm 85mm and 100mm), but with the added bonus of offering a wide f/1.8 aperture - something which you won't find in 100mm prime lenses.

Not content with just the one optic in the Global Vision Art series of fast-aperture lenses, Sigma's engineers have burnt the midnight oil and produced their second f/1.8 zoom, which was showcased for the first time at the CP+ show in Japan earlier this year.

The Sigma 50-100mm f/1.8 DC HSM ART is a quite awesome tele-zoom lens for portraits - it is very sharp in the image center and it has a very good bokeh. However, at least technically it has its weaknesses. The outer image field is good but it stays short of brilliant.

With a focal range that covers many popular prime lenses and a super-fast maximum aperture, this lens is sure to appeal. For the cash, prospective buyers will get a well-built optic that can really perform when wide-open, particularly at 50mm.

First quick impressions: - very sharp at 1.8 - very smooth and creamy bokeh - extremely high build quality...the zoom ring smoothness is otherworldly - i have not experienced any focus issues so far...auto-focus is fast and silent..
