Sony SEL075UWC 21 mm f/2.8-22 Ultra Wide Converter Lens for Mirrorless Cameras

The 21mm Ultra-Wide Conversion Lens for FE 28mm f/2 Lens from Sony broadens the angle-of-view of the 28mm f/2 lens to 92º for an ultra-wide focal length equivalence of 21mm when used with full-frame cameras. As this converter lens is uniquely compatible with the FE 28mm f/2 lens, it transmits EXIF data through the host lens to the camera. When used with a 28mm lens, the converter lens’s four elements in four groups of optical architecture yields a maximum aperture of f/2.8 and a minimum manual focus distance of 7.9″. The converter lens offers a 68° angle of view and a 31.5mm focal length equivalent when used with an APS-C E-Mount camera. It is a compact addition to the 28mm lens with a bayonet mount and features a built-in petal-type lens hood.
