SIGMA LENSES FOR SONY MANUAL

Sigma is calling the 105mm F1.4 DG HSM Art the 'bokeh master,' which we're assuming is the karate equivalent to a black belt. While it will be available for Sony E-mount, Sigma plans to develop the lens for Canon mount lens with Canon Lens Aberration Correction function, the Sigma Electronic Flash Macro EM-140 DG, and Sigma Teleconverters. Nine rounded diaphragm aperture blades offer a F2.8 - F22 aperture range. Optically, 13 elements in 10 groups include two FLD (“F” Low Dispersion), two SLD (Special Low Dispersion), and two aspherical elements to enhance image performance.

The focus-by-wire system and coreless DC motor adjusts focus with 'optimal speed and low noise.' Manual focus is available even in autofocus. The 70mm F2.8 DG MACRO features an extending, floating, two-group focus mechanism to minimize aberrations. The brass bayonet mount has a 'special surface treatment' to add strength and rubber seals adds to its dust-and-splash-proof design. In-camera image stabilization will be supported along with in-camera aberration correction-specifically correcting peripheral illumination, chromatic aberrations, and distortion. They're also noting compatibility with Sony’s Fast Hybrid AF, AF-C mode, and high-speed focus, something the Mount Converter MC-11 did not address. The Sony E-mount models will cover 14mm to 135mm and tout a 'newly developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed.' Basically, Sigma is saying the autofocus system has a similar performance level to other E-mount lenses, e.g. While the Art line is aimed at photographers, video shooters can take advantage of their optical performance. On the heels of the company's $1,300 14-24mm F2.8 DG HSM Art (Nikon F, Canon EF) announcement, the lens designer says it will roll out nine prime lenses for E-mount in its Arts series, two of which are brand new: the 70mm F2.8 DG MACRO and the 105mm F1.4 DG HSM.

Good news for those who shoot Sony full frame E-mount and enjoy the look of Sigma optics.
