Design and Features
The lens barrel is 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 62 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).
