The lens is mounted with Sigma's very own MC-11 adapter giving the camera autofocus ability. A remarkable feat of design, this Sigma zoom lens is the first of its kind - a wide to standard zoom with a fast f1.8. The lens is ideal for landscapes, portraits, still life, snap shots, casual, and close-ups. Sigma’s DC lenses are designed for cropped sensors and the image circle on this lens is designed to match the smaller size of the image sensor on small-frame sensor cameras (DX-format on Nikon and EF-S on Canon). Its new Global Vision design works with its compatibility with the Sigma USB dock for further customisation.
SIGMA 18 35 SONY SERIES
This lens incorporates a wide glass molded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle. Considering the Sigma 18-35 f1.8 for my Sony a6300 Hi everyone, I am an owner of a Sony a6300 and the lenses every Sony a6000 series camera owner seems to rave about are these three lenses in particular: the Sigma 16mm f1.4, the Sigma 30mm f1.4, and the Sigma 18-35 f1.8 (with MC-11 adapter). The 9 blade rounded diaphragm creates an attractive round bokeh at large-aperture settings, while the HSM (Hyper Sonic Motor) ensures a silent, high-speed AF. The Sigma 18-35mm is a standard zoom lens that offers a focal range equivalent to 27-52.5mm in the 35m format. The Sigma 18-35mm T2 Cine High-Speed Zoom Lens with a Sony E-mount and with focus scales marked in feet provides an image circle that covers Super 35mm-sized. This allows for both beautiful bokeh effects and high optical performance. This lens is designed to provide the same ultra-high optical performance that is expected of a fixed focal length lens.
