The Sigma 35mm f/1.4 Art Lens and MC-11 Mount Converter Kit allows you to use Sigma's newest series of lenses, the Global Vision series, on your Sony E-Mount cameras with full compatibility.
The 35mm offers superb resolution and excellent bokeh at its impressive
maximum aperture of f/1.4. Also, with a rounded 9-blade aperture, users
will see smooth, pleasing bokeh. For maximum quality, the 35mm Art uses
one FLD and four SLD glass elements as well as two aspherical elements
and a Super Multi-Layer Coating which all work together to combat
aberrations and flare. Operation is fast thanks to a Hyper Sonic AF
Motor and it has manual focus override with the large focusing ring.
Additionally, it is made from a lightweight, yet durable, Thermally
Stable Composite material and has a rugged brass bayonet mount. It is
compatible with Sigma's USB Dock for firmware update and fine tuning.
The MC-11 Mount Converter enables the use of Sigma Canon EF-mount lenses
on Sony E-mount mirrorless camera bodies, and maintains full lens
performance, including autofocus and auto-exposure, as well as in-camera
correction technologies. An integrated LED can be used to display
select Sigma lens compatibility with the adapted camera body, and the
adapter also supports in-camera image stabilization. In order to
maintain a high degree of image quality, the interior of the adapter is
flocked to reduce reflections, and it also retains full EXIF data to
benefit post-production and file management.
