Designed for Sony E-mount cameras, the 7.5mm f/2.8 Fisheye Lens from 7artisans Photoelectric is an ultra-wide fisheye lens with completely manual operation. It covers sensor sizes up to APS-C, offering an equivalent focal length of 11.25mm. With an angle of view of 180°, the lens features a dramatic perspective that bends straight lines and exaggerates the distance between subjects. An 11-blade diaphragm offers a relatively bright maximum aperture of f/2.8 and can be stopped down to a minimum of f/22 to improve depth of field.
The lens' optics feature 11 elements in 10 groups that are treated with a multi-layer high permeability coating, which helps reduce reflections and improve image quality. They can be focused down to a minimum distance of 4.7", allowing you to get relatively close to your subject despite the ultra-wide frame. Both the manual focus and aperture rings are knurled to improve grip, and a petal-type hood is built into the front to help block stray light and reduce the incidence of flares and ghosting. Made to be durable yet lightweight, the lens body is made with aluminum and features a copper bayonet for precise mounting.
