This dedicated ultra-wide converter for the FE 28 mm F2 lens provides an even wider 21 mm focal length, and because it is specifically designed for the full-frame FE 28 mm F2 it delivers imposing wide perspective with high resolution throughout the image area from infinity down to the closest focusing distance, without compromising lens image quality.2 The sophisticated design seamlessly matches the lens, and is dust and moisture resistant for maximum reliability.
A 21 mm focal length makes it possible to capture sweeping views with impressive perspective indoors or out, particularly when shooting in the full frame format.
A 21 mm focal length not only allows you to capture wider scenes, whether you’re shooting scenery outdoors or a group of people indoors, for example, but it is also capable of producing strong perspective that can emphasize the size of objects in the foreground as well as the distance between foreground and background objects.
A sensor system detects when the converter is mounted so that appropriate EXIF lens data is generated and recorded by the camera. That makes data management easier when you sort or process your images later.
Not only are the Ultra Wide Converter optics designed specifically for the FE 28 mm F2, but the visual appearance is too. The converter blends smoothly with the lens when mounted, giving the appearance of a single integrated unit.
Like the lens it mounts to, the Ultra Wide Converter has been designed to resist the intrusion of dust and moisture so it can be used with confidence even in challenging outdoor conditions.
