12-24 mm

Sony full-frame lenses

Posted on Updated on

Sony has announced two new additions to its full-frame E-mount lens lineup, the FE 16-35 mm f/2.8 GM and the FE 12-24 mm f/4 G.

The 16-35 mm zoom is the first wide-angle G Master model, and features exceptional corner-to-corner sharpness, says the company, with an optical design that includes five aspherical elements, two of which are Sony’s original XA (extreme aspherical) elements that reduce aberration and deliver the ultimate resolution throughout the entire zoom and aperture range, it notes. The front XA element is the largest XA element ever produced, Sony claims. Additionally, two ED (Extra-low-Dispersion) glass elements keep chromatic aberration to a minimum while maximizing resolution, and Sony’s Nano AR coating suppresses internal reflections to ensure excellent image contrast and clarity.

The lens features a near circular aperture shape at all settings, producing images with sharply focused subjects and beautifully defocused backgrounds or “bokeh.” It also has two DDSSMs (Direct Drive SSM) that compose a floating focusing system and ensure that AF acquisition is speedy and quiet.

The 16-35 mm lens is also dust and moisture resistant, has a fluorine coating on the front lens that helps to both prevent dust or grease marks and remove them easily if they do become a trouble.  There is also a customizable focus hold button and a hood release button.

The 12-24 mm lens produces outstanding image quality in a compact, lightweight design, notes Sony. weighing in at approximately 20 oz.

The lens features an innovative optical design with four aspherical elements that ensure excellent corner to corner sharpness and resolution. Additionally, the lens has three ED glass elements and one Super ED glass element to minimize chromatic aberration throughout the entire image. The lens also includes Sony’s Nano AR coating.

The 12-24 mm lens includes a DDSSM (Direct Drive SSM) for fast, quiet and precise AF performance, plus a customizable focus hold button and focus mode switch.  It is also dust and moisture resistant.

The Sony FE 16-35 mm f/2.8 GM will ship this August and will be sold for about $3,000.

The FE 12-24 mm f/4 G will ship this July and sell for about $2,300.

Three Sigma lenses

Posted on

Photokina – Sigma has added the 85 mm f/1.4 DG HSM Art, 12-24 mm f/4 DG HSM Art and 500 mm f/4 DG OS HSM Sport to its Global Vision lens line.

The 85 mm lens is engineered to support the highest resolution sensors on the market with an exceptional degree of sharpness. The high-performance optical system is purpose-built by Sigma to produce an attractive bokeh effect. The lens’ advanced architecture features two SLD (special low dispersion) glass elements and one glass element with a high rate of anomalous partial dispersion and refraction. A re-engineered AF system brings 1.3X the torque of its predecessor, while other features such as a full-time manual focus override have been added, which can be controlled when the focus ring is rotated, even during continuous AF.
The Sigma 85 mm f/1.4 DG HSM Art lens supports Canon, Nikon and Sigma mounts. The Nikon mounts feature a brand new electromagnetic diaphragm. The lens will be available in late October.

The 12-24 mm lens features the largest aspherical glass mold in the industry, offering photographers an ultra-wide angle zoom with virtually no distortion, flare or ghosting. Lens performance highlights include constant f/4 brightness and the brand new Sigma AF system with 1.3X torque boost. The lens features elements made with FLD (“F” Low Dispersion) glass, which is equivalent to calcium fluorite in performance. Combined with an optimized power distribution, the result is outstanding image quality from center to edges. Minimum focus distance is 9.4 inches at 24 mm.

The Sigma 12-24 mm f/4 DG HSM Art lens supports Canon, Nikon and Sigma mounts. The Nikon mounts feature the brand new electromagnetic diaphragm. The lens will be available in late October.

The flagship Sigma super telephoto 500 mm lens incorporates the very latest in Sigma optical technology and innovation. Designed for the professional sports and wildlife shooter, the ultra-durable lens features magnesium alloy components, a carbon fibre hood, a water and oil resistant front element, and is dust and splash proof. The lens features a drop-in rear filter slot for polarizers, UV and other filters.

The lens incorporates two FLD and one SLD glass elements, while the optimized power distribution helps minimize spherical aberration and axial chromatic aberration. The optical system also effectively minimizes transverse chromatic aberration, which can affect the edges of the shots taken in the telephoto range. In addition, image quality remains exceptional when the lens is used with a Sigma Telephoto Converter (sold separately).

Other key performance features include Sigma’s two-mode Optical Stabilizer for enhanced performance when shooting handheld for still subjects or panning and tracking for moving subjects. There is also a customizable AF “return” function for setting the focus position of one’s choice and returning to that preset distance.

The Sigma 500 mm f/4 supports Canon, Nikon and Sigma mounts. The Nikon mounts feature the brand new electromagnetic diaphragm. The lens, in Canon and Sigma mounts, will be available in late October. The Nikon mount will be available in late November.

 Two new lenses join the Samsung NX family, a 12-24 mm f/4-5.6 ED (equivalent to 18.5-37 mm) and 45 mm f/1.8 prime (equivalent to 69.3 mm).

The lenses are compatible with Samsung’s i-Function system.

The 12-24 mm lens, with 10 elements in 8 groups, weighs 208 g, has one extra low dispersion glass lens and two aspherical glass lenses which are said to guarantee superb sharpness and low chromatic aberration.

The 45 mm lens, with 7 elements in 6 groups, has a stepping motor for a fast and super-quiet AF, weighs 115 g (without the hood), and has a solid metal body and metal mount.
