The Kowa PROMINAR MFT 25mm Lens, in silver, is a standard focal length manual focus lens for the Micro Four Thirds sensor format. Compact, stylish, and featuring advanced optics and Japanese construction drawing on 60+ years of Kowa's optical heritage, the lens is a suitable choice for sophisticated MFT cameras such as the Panasonic GH5. It features a 9-blade circular iris with f/1.8 and T1.9 maximum aperture and T-stop, and is designed with 8 lens elements in 6 groups. It is a fully multi-coated XD lens (extra-low dispersion glass) that can help you achieve reduced chromatic aberration.
A Dual Link Iris system allows you to switch between silent and click-stop aperture adjustment.
A 9-blade aperture ensures that the diaphragm is circular at all f-stops, providing for a more natural impression.
Floating Mechanism System
The floating mechanism system is effective in preventing malfunction and increasing the life of the lens. Tests have shown high optical performance at all supported subject distances.
Aluminum Alloy Construction
All internal parts are protected by a solid and rigid aluminum housing.
