Sigma's latest 18-35mm f/1.8 DC HSM Lens is now available to order. Typically most zoom lenses can only maintain a max aperture of F/2.8, while this new (35mm Equivalent Focal Length of 28.8-56mm) lens can maintain a constant wide aperture of F/1.8 throughout it's zoom range, thus dubbing it The Fastest Zoom Lens in the World.
These are some very very impressive specs for a lens. The new Sigma 18-35mm F/1.8 lens is offered in Canon, Nikon, Sony, Pentax, and Sigma mounts. Keep in mind that many of these lenses can now be adapted to work with other cameras such as the Sony NEX (including aperture controls and auto focus). The Canon version of this lens is listed as native Canon EF (not EF-S), and although it's designed for APS-C sized sensors (like Tokina's 11-16mm), this lens should mount directly to a BlackMagic Design Cinema Camera with EF mount. This could be a very popular lens for BMCC users.
I'm personally very excited to get my hands on a singe lens with this type of focal range combined with a very fast constant aperture. The fastest zoom lens I currently have is Canon's 24-70mm F/2.8 which runs over $2K so the fact that this new Sigma 18-35mm F/1.8 is available for under $800 dollars is an amazing price. This should appeal to many who shoot with APS-C cameras such as a Canon Rebel, 7D, 60D, T5i, or even Sony NEX cameras with a smart adapter.
