The Sigma has announced the world’s first f/1.8, ultra-wide, full-frame prime lens called the – Sigma 14mm F/1.8 GD HSM Art Full-Frame Lens. The lens designed for high resolution cameras and ideal for shooting architecture, astrophotography, documentary and landscapes. The optical formula gets pretty interesting to create a lens this wide and fast, integrating three FLD glass elements, and four SLD glass elements in order to cut down on chromatic aberration.
The lens designed for cameras with 36 × 24 mm sensors, the new Sigma 14mm F/1.8 GD HSM Art Full-Frame Lens offers an ultra-wide angle of view with a large maximum aperture, which is ideal for night photography. The lens is boasting outstanding image quality from center to edge, and it features the largest glass mold (80 mm) in the industry, and provides photographers an ultra-wide prime with virtually no distortion, flare or ghosting.
In terms of optics, it uses 16 elements in 11 groups, including a large 80 millimeter diameter precision-moulded glass aspherical lens as its front elements. Plus it also features three “F” Low Dispersion (FLD) and four Super Low Dispersion (SLD) glass elements.
According to the company, this technology has made possible the 14mm f/1.8 specification – the first of its kind of lenses. The maximum f/1.8 aperture supports photography with a very shallow depth or field to make the subject stand out dramatically against a softy blurred background.
The lens features a Sigma’s latest autofocus technology and full-time manual override. In addition to the great IQ from edge to edge, the new lens offers a superfast and efficient AF system. The lens also offers minimum 10.6 inches, so photographers can compose incredible close-up shots with expansive background.
The new lens supports Canon, Nikon and Sigma mounts and works with Sigma’s MC-11 Sony E-mount converter. The lens measures at 95.4 × 126 millimeters (diameter × length) and weighs 1,170 grams. Pricing and availability for the new lens will be announced later.
