Sigma announced their pricing and availability for their whopping 120-300mm f/2.8 DG OS HSM lens. This lens, designed for Sigma's Sports lineup, is the first in a series of lenses created for sports and wildlife photographers. The Sigma 120-300mm f/2.8 has been redesigned with updated mechanics and performance from its predecessor released in February 2011.

The newly redesigned 120-300mm f/2.8 lens features 23 elements in 18 groups. It has a 9 blade diaphragm for a smooth bokeh effect. The lens has a minimum focusing distance of 59.1- 98.4 inches.

The lens was designed for full frame cameras, but can also be used on APS-C cameras. The OS (optical stabilization system) allows the lens to compensate for camera shake that occurs with long lenses while being hand held. And the HSM motor features quite and fast autofocus. Two FLD glass elements are part of the construction of this lens. These elements have performance equal to fluorite. In addition, one SLD element is included to reduce color aberration. Lenses in the Sports category will offer a higher level of customization through the Sigma USB dock. Also, these lenses will be dust and splash proof.

The 120-300mm f/2.8 DG OS HSM lens will have a street price of $3,600 and will be available starting in May.

Also announced today is Sigma's USB Dock. This dock allows users to update the lens' firmware and adjust parameters such as focus. The lenses from the Sports line have customizable AF speed, focus limiter and OS function. Retailing at a shockingly low $59, this little device is a must-have for anyone with a Sigma lens from their new Contemporary, Art and Sports lines. The USB Dock will be available in early May.
