Picture of Ultra Wide Converter

New expression with a wider view

A 21mm focal length makes it possible to capture sweeping views with impressive perspective indoors or out, particularly when shooting in the full frame format.

Wide 21mm an advantage indoors or out

A 21mm 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 emphasizes the size of objects in the foreground as well the distance between foreground and background objects.

Automatic EXIF data generation

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.

Smooth visual match with the FE 28mm F2

Not only are the Ultra Wide Converter optics designed specifically for the FE 28mm F2, but the visual appearance is too. The converter blends smoothly with the lens when mounted, giving the appearance of a single integrated unit.
