Is that my jaw that just hit the floor? I am pretty excited about Sigma's newest lens release: the Sigma 18-35mm F1.8 DC HSM Art lens -- the first zoom lens to give users a maximum aperture f1.8 throughout the entire zoom range. I can not wait to get my hands on this lens!
The Sigma 18-35mm f/1.8 lens is a wide aperture zoom created for DSLR cameras with APS-C size sensors. After figuring in the crop factor, the lens translates to a focal range of 27-52.5mm in 35mm equivalent. This focal length makes the lens perfect for landscapes, portraits, wedding, studio, close-up and street photography.
"Exceptionally fast apertures were previously unavailable in zoom lenses, so photographers turned to several prime lenses in a session to get bright images at various focal lengths. We're incredibly excited to be the first manufacturer to bring the F1.8 standard zoom to the market and to provide photographers with a new level of creativity and convenience, with the outstanding image quality at the core of the new Sigma Global Vision," said Mark Amir-Hamzeh, president of Sigma Corporation of America.

The lens is constructed of 17 elements in 12 groups. It has a minimum aperture of f/16 and a 72mm filter size. It has a nine blade rounded diaphragm that should produce some very sweet bokeh. The 18-35mm lens incorporates an AF/MF switch and the use of Thermally Stable Composite (TSC) compound material; allowing the lens to perform well at extreme temperatures. This product also reduces the size and weight of the lens which measures 3.1" x 4.8" and weighs 28.6oz.
Compatible with Sigma's USB dock, photographers will be able to update lens firmware and adjust focus parameters from their computers instead of having to send in their lenses and lose precious time with them.
The 18-35mm lens has a Super Multi-Layer Coating that reduces flare and ghosting. It promises to provide sharp and high contrast images, even in backlit conditions. The petal-type hood that is supplied with the lens will provide extra protection from flare and ghosting. Sigma's Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function.
Sigma has yet to announce a price or date that the 18-35mm f/1.8 lens will hit the shelf. I'm hoping that is not an indication of an extremely high price tag. I know countless photographers that would love to add this lens in their camera bag...if the price is right.
