(From Sigma lens literature) This lens transforms a large-aperture f/2.8 300mm lens into a zoom lens that allows you to determine the picture composition you want without having to change your vantage point. It has two SLD (the special low dispersion) glass elements in front group and another element of SLD is being used for rear group for excellent correction of chromatic aberration.

The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom range.

The AF drive for Sigma SA, Canon and Nikon cameras is equipped with a silent, responsive and high speed HSM , which also provides full-time manual focus function.

Since focusing and zooming do not change its overall length, this lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and use.

High-speed focusing is possible when this lens is used with dedicated APO EX tele-converters (1.4x and 2x). By adding an APO tele-converter, which is sold separately, you can use this lens as a 168-420mm f/4 AF tele-zoom lens with a 1.4x tele-converter, or as a 240-600mm f/5.6 AF ultra-telephoto zoom lens with a 2x tele-converter. It is also possible to use AE (Automatic Exposure) function, even when EX Tele-converters are attached to the lens.

Sigma 120-300mm f/2.8 EX DG HSM APO User Reviews

    Good color, contrast, bokeh, speed and sharpness,
    AF could be faster, slight softness wide open

    This is a great zoom range for the sports and aviation shooter. Nikon needs to cover this range with a VR lens. This lens would benefit from Sigma's new Optical Stabilization (OS). I bought this lens used and have used it for aviation mainly, but also some children playing shots, on my D300 (1.5 crop). I've shot it almost all handheld. When using it for kids playing (similar to sports), the focus speed limitations start to show. But then, I'm spoiled with the fast focus of the Nikon 70-200 AFS VR. It's slightly soft at 2.8/300mm and gets better as it's stopped down, coming to very sharp at f5.6 and seemingly even better at f8. I haven't shot enough at the lower end of focal length to judge. Color and contrast are amazing. It gives a great bokeh that is nice and soft/creamy. This is a pro piece of glass and its heavy at around 6lbs. Corners look great on my D300, but you'd expect that of a fullframe lens on a 1.5x crop camera. I suspect this lens will get updated with OS soon and it would make this excellent lens even better. This lens seems to be very popular, yet SLRgear has yet to test it or the 100-300 f4 Sigma that both have a large Nikon following due to lack of coverage from Nikon. SLRgear would be serving the photographic community well to test both of these lenses.

    Speed, versatility, range coverage, relative cost, calibration capabilities
    weight, filter size, lack of IS/OS/VR

    I get these lenses to shoot concerts and sports events. And I love the versatility of it. At 2,8 is a bit soft, but at 3,2-3,5 its great for the purpose(high speed@low-light@long distance).
    For portraiture I recommend the Canon EF70-200/2,8 USM IS L(I use mainly the Canon system).
