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..

The Sigma 50-100mm F1.8 DC HSM Art ($1,099) is a premium telezoom lens, aimed at photographers working with APS-C SLRs. It's designed around the same principle as the standard 18-35mm F1.8 DC HSM Art ($698.99 at Amazon) zoom, and is likely to appeal to the same demographic. It's a bright lens, maintaining an f/1.8 aperture throughout its range, that makes no compromises on image quality compared with shooting prime lenses. That requires quite a bit of glass, and when coupled with a tough build you've got a big, hefty lens. It omits image stabilization and is on the pricey side, but optical performance is superb. It's an excellent option if you're in the market for a wide-aperture telezoom for your APS-C SLR. Design The 50-100mm F1.8 ($948.05 at Amazon) is a big lens. It measures 6.7 by 3.7 inches (HD), weighs 3.3 pounds, and supports 82mm front filters. The barrel is a mix of metal and polycarbonate, with a metal tripod collar that rotates and locks into position every 90 degrees...

The Sigma 50-100mm F1.8 DC HSM Art is an appealing lens for APS-C SLR owners who want a bright telezoom, but it's on the pricey side.
