Designed for Canon M-mount cameras, this 12mm f/2.8 Lens from 7artisans Photoelectric is an ultra-wide prime lens with completely manual operation. It has an equivalent focal length of 18mm, offering an angle of view of around 102° for a dramatically broad perspective of your subjects. A 7-blade diaphragm offers a relatively bright maximum aperture of f/2.8, and can stop down to f/16 for improving the depth of field or reducing exposure.
The lens' optics features 10 elements in 8 groups that are treated with a multi-layer high permeability coating, which helps reduce reflections and improve image quality. With a minimum focus distance of 7.9", the lens allows you to get relatively close to your subjects despite the wide frame. Both the manual and aperture rings are grooved to improve grip and are complemented by an engraved depth of field scale for easy operation. On the front, a built-in petal-type lens hood helps reduce the amount of flares, while a 77mm front filter thread allows you to mount a wide variety of optional filters.
