Sony 21mm Ultra-Wide Conversion Lens for FE 28mm f/2 Lens
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. This converter lens is uniquely compatible with the FE 28mm f/2 lens, so it transmits EXIF data through the host lens to the camera. The optical design of the converter lens is comprised of 4 elements in 4 groups. When on the 28mm lens, it provides a maximum aperture of f/2.8 and a minimum manual focus distance of 7.9". When the lens is used with an APS-C E-Mount camera, the converter lens provides a 68° angle of view and a 31.5mm focal length equivalent. It is a compact addition to the 28mm lens with a bayonet mount and a built-in petal-type lens hood.
This dedicated ultra-wide converter for the FE 28mm F2 lens provides an even wider 21mm focal length, and because it is specifically designed for the full-frame FE 28mm F2 it delivers an imposingly wide perspective with high resolution throughout the image area from infinity down to the closest focusing distance, without compromising the lens’s image quality. The sophisticated design seamlessly matches the lens and is dust and moisture-resistant for maximum reliability.
