Sigma has officially lifted the veil on two new Global Vision lenses, the 50–100mm f/1.8 DC HSM Art and 30mm f/1.4 DC DN Contemporary.
In addition to two new pieces of glass, Sigma has unexpectedly announced the MC–11, a lens mount converter for attaching Sigma glass to Sony E-mount cameras.
50–100mm f/1.8 DC HSM Art
First up is the new Sigma 50–100mm f/1.8 DC HSM Art, a lens Sigma claims is the first constant f/1.8 aperture telephoto zoom lens. Based on the same framework as Sigma’s 18–35mm f/1.8 DC HSM, the 50–100mm f/1.8 DC HSM Art lens has a 35mm equivalent range of 75–150mm.
It’s optical construction consists of 21 elements in 15 groups, including three low dispersion elements, one Special Low Dispersion (SLD) element and one high-high-refractive index, high-dispersion glass element, all of which come together to reduce chromatic aberration and ghosting.
The Hyper Sonic Motor (HSM) driving the autofocus is 30% slimmer than its predecessors and is said to provide faster and more accurate autofocus. The internal aperture diaphragm is made up of polycarbonate with integrated fluorine and carbon feather film for smoother operation.
The minimum focusing distance is 37.4in and the lens weighs in at 52.6oz.
The new 50–100mm f/1.8 Art will be available in Canon, Nikon and Sigma mounts for $1100. No word on exact availability.
30mm f/1.4 DC DN Contemporary
Next up is Sigma’s new 30mm f/1.4 DC DN Contemporary lens. Designed to offer great performance at an even better price, the 30mm F1.4 DC DN Contemporary is a perfect pairing for those who want a fast and standard lens on their mirrorless cameras.
The lens is comprised of 9 elements in 7 groups, including one aspherical element and one double-sided aspherical element for reducing chromatic aberration and flaring.
It’s autofocus is driven by a stepping motor, designed to work fast and smooth for both still and video applications. The lens weighs in at only 9.3oz and offers a minimum focusing distance of 11.8 inches.
The new Sigma 30mm F1.4 DC DN Contemporary Lens will be available in Sony E-Mount and Micro Four Thirds mount. A release date has not yet been confirmed, but Sigma does note the lens will retail for $340.
MC–11 Lens Converter
Last, but by no means least, Sigma announced the MC–11, a new high-performance lens converter that will allow Sony E-mount users to mount any of Sigma’s 19 Global Vision lenses to their full frame and APS-C sensor cameras.
The adapter will work with both Canon and Sigma mount versions of Sigma’s Global Vision glass. In addition to mounting all of the glass, the LCD display on the adapter will let you know what lenses are compatible and what lenses will need to have the firmware updated to operate correctly.
Built into the adapter is a collection of information that will allow it to automatically make adjustments depending on what lens and camera body is attached to it, most notably correct image stabilization when an OS lens is or isn’t used in conjunction with Sony’s in-body stabilization systems. Complementing these features is the ability for the adapter to store and transmit EXIF data to the camera so information can be used in post-production and archival purposes.
A release date has not yet been given, but the MC-11 will sell for an estimated $250.
