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.
