Design and Features
Rebranded Minolta 20mm F/2.8 RS.
The lens barrel is compact, of moderate weight, made of plastic. The lens mount is metallic.
The lens lacks focusing mode switch, therefore you have to set the automatic or manual focus mode from the camera. Direct Manual Focus is available.
The lens uses front filters with standard size of 72 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
The focusing ring rotates during autofocus which looks pretty anachronistic by today's standards. It is strongly recommended not to touch the ring or manually stop its movement because it might result in damage to the lens and/or camera.
