Sigma announces nine full-frame E-mount Art primes

Sigma has announced plans to bring seven of its existing full-frame Art-series primes, plus two newly-announced lenses, to E-mount. Sigma says that the E-mount versions will offer "a newly developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed." The lenses will work with Sony's AF-C mode, and as with existing lenses adapted via MC-11, will work with in-camera stabilization and in-camera lens corrections.

Below are the lenses Sigma plans to offer in E-mount:

• 14mm F1.8 DG HSM | Art
• 20mm F1.4 DG HSM | Art
• 24mm F1.4 DG HSM | Art
• 35mm F1.4 DG HSM | Art
• 50mm F1.4 DG HSM | Art
• 70mm F2.8 DG Macro | Art
• Sigma 85mm F1.4 DG HSM | Art
• Sigma 105mm F1.4 DG HSM | Art
• Sigma 135mm F1.8 DG HSM | Art

Sigma says that launch dates for all models are yet to be determined.

SIGMA launches seven interchangeable Art prime lenses for Sony E-mount cameras with full-frame sensors

SIGMA Corporation is pleased to announce the upcoming launch of interchangeable lenses for the Sony E-mount digital camera series with full-frame image sensors. SIGMA will gradually introduce the lenses as members of the Art line, which offers photographers the highest level of optical performance.

While offering the same high-performance optical design as other lenses in the Art line, the new Sony E-mount models will feature a newly developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses will be compatible with Sony’s Continuous AF (AF-C) and high-speed autofocus, which are not addressed by SIGMA MOUNT CONVERTER MC-11. Like the converter MC-11, the lenses will be compatible with in-camera image stabilization and in-camera lens aberration correction, which includes corrections for peripheral illumination, chromatic aberrations, and distortion.

The lineup will include the Art line set of seven prime lenses covering 14mm to 135mm. It will also include two models that SIGMA will be exhibiting at CP+ 2018: 70mm F2.8 DG MACRO | Art and 105mm F1.4 DG HSM | Art (launch date TBD). Further, SIGMA plans to introduce additional Sony E-mount models in the Art line going forward.

Note: This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation.

Key features

1. Autofocus tuned for each lens
Thanks to an autofocus drive control program tuned for each lens and high-speed data transmission, the lenses will offer high-speed autofocus at the same performance level as that of a lens designed exclusively for mirrorless cameras. In particular, in E-mount cameras offering Sony’s Fast Hybrid AF, AF-C mode will deliver exceptional subject following performance. Moreover, autofocus will remain extremely precise even in those E-mount cameras offering only contrast AF.

2. Compatible with in-camera image stabilization
The lenses will be compatible with in-camera image stabilization. The Sony E-mount camera senses the focal length of the lens and automatically optimizes image stabilization performance.

3. Data loaded for compatibility with in-camera aberration correction The lenses will be fully compatible with in-camera aberration correction, which includes corrections for peripheral illumination, chromatic aberrations, and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.

4. Native mount for a more rigid and stable feel Making the mount native to the lens makes possible a more rigid and stable feel to the lens. Featuring a special surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.

5. Available Mount Conversion Service This service converts the mount of SIGMA lenses to that of a different camera body, allowing photographers to continue using their favorite lenses over the long term regardless of camera system.

Note 1: The Mount Conversion Service is different from a normal repair. In order to apply for the service, please contact your nearest authorized SIGMA subsidiary or distributor. http://www.sigma-global.com/en/about/world-network/

Note 2: This service is performed exclusively by SIGMA.
