Designed for Micro Four Thirds cameras, this black 25mm f/1.8 Lens from 7artisans Photoelectric is a wide prime lens with completely manual operation. It covers sensor sizes up to the APS-C format, offering an equivalent focal length of 50mm that is well-suited for street shooting and travel photography. A rounded 12-blade diaphragm offers pleasing bokeh and smooth out-of-focus areas, with a bright maximum aperture of f/1.8 for low-light photography that can be stopped down to f/16 to improve depth of field.
The lens' optics feature 7 elements in 5 groups that are treated with a multi-layer high permeability coating, which helps reduce reflections and improve image quality. Both the manual focus and aperture rings are knurled to improve grip and are complemented by an engraved depth of field scale for easy operation. Other features include a minimum focus distance of 7.1" for close-up shots and a 46mm front filter thread for mounting a wide variety of optional filters.
