Sigma Announces 8-16mm Wide Angle Lens
By Matt J. Weiss, February 21, 2010 @ 12:43 PM (EST)
Sigma announced a huge line up of lenses and cameras at PMA, but the 8-16mm f4.5-5.6 rectilinear wide angle lens is the highlight for underwater photographers. The lens is designed for APS-C sensors and offers a maximum range of view of 121.2 degrees and will fit Canon, Nikon, Pentax, Sigma and Sony SLRs. The focal length and close minimum focus distance of 24cm (9.4") make it a useable underwater lens.
This lens will struggle to compete with Tokina 10-17mm in the ultra wide angle lens field for underwater photographers, as the Tokina is a faster lens and focuses closer than the Sigma 8-16mm.
The major difference is that the Sigma is a rectilinear lens, and if you require straight lines in your images and want to avoid barrel distortion, which is helpful in certain kinds of photography.

The Sigma Corporation is pleased to announce the new Sigma 8-16mm F4.5-5.6 DC HSM. This is the first ultra wide zoom lens with a minimum focal length of 8mm, designed specifically for APS-C size image sensors. This lens has an equivalent angle of view of a 12-24mm lens when used on digital cameras with an APS-C size image sensor.
The wide-angle of view from 121.2 degrees* produces striking images with exaggerated perspective, enabling photographers to emphasize the subject. Four FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, compensate for color aberration. One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism.
Incorporating an inner focusing system, the lens produces high definition images throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range.
This lens incorporates HSM (Hyper Sonic Motor), ensuring quiet and high speed AF as well as full-time manual focus capability. It has a minimum focusing distance of 24cm throughout the entire zoom range which allows photographers to emphasize the subject by creating exaggerated perspectives. This lens has a compact construction with an overall length of 105.7mm and a maximum diameter of 75mm.
*The angle of view varies depending on which camera the lens is mounted on.

I love to get in close, Stalk and study behavior. Doing so without a re-breather is no easy task. I was taught to minimize the distance and water between the subject and your lense. Paint a little color with a complementing...
