Design and Features
The lens barrel is compact, of moderate weight, made of plastic. The lens mount is plastic.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode without Direct Manual Focus.|
|MF||Manual focus mode.|
The lens uses front filters with standard size of 49 mm which are easy to find. They are also inexpensive.
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.
