Design and Features
The lens barrel is compact, of moderate weight, made of high-quality 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. Full-Time Manual Focus is not 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).
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.
- The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3400, D5000-D5600 SLR cameras.
The lens incorporates a floating system that provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. Learn more
