Design and Features
The lens barrel is of moderate weight, made of plastic. The lens mount is metallic.
The lens features AF/M focus mode switch.
|AF||Autofocus mode without Full-Time Manual Focus.|
|M||Manual focus mode.|
The lens features focusing distance range limiter which allows to choose between the following focusing distance ranges:
|NORMAL||Full range of focusing distances.|
|MACRO - ∞||Range of focusing distances suitable for shooting nearby subjects.|
By setting the suitable focusing distance range, the actual autofocusing time can be shorter.
The lens uses front filters with standard size of 58 mm which are easy to find. They are also inexpensive.
Versions of the lens for Canon EF, Nikon F и Sigma SA mounts do not feature optical image stabilizer. It is a significant disadvantage for a lens of such class - the need for image stabilization only grows with increasing of focal length. In order to obtain sharp images with this lens, you will need to use a tripod or shutter speeds not longer than 1/300 second (at focal length of 300 mm) which may require in some cases increasing the ISO setting and will lead to noisy images.
