The Sony 21mm Ultra-Wide Conversion Lens is an add-on accessory lens designed specifically for the Sony FE 28mm f/2. Key features include:
- Ultra-Wide Conversion. When attached, this conversion lens converts the normally FE 28mm lens to a 21mm ultra-wide, expanding the field of view from 75º to 92º while still covering full-frame sensors. Since it’s designed specifically for the FE 28mm, EXIF data is transferred to the camera. Do note that the 21mm Ultra-Wide Conversion reduces the maximum aperture of the lens to f/2.8.
- Optics. The conversion lens is comprised of four elements in four groups and has minimal affect on image quality. The built-in petal hood helps to minimize lens flare.
Please Note: This conversion requires the use of the Sony FE 28mm f/2, which is a separate rental item. It will not mount to a camera without the host lens.
