Design and Features
The lens barrel is large, heavy, made of metal. The lens mount is metallic.
The lens features AF/M focus mode switch.
|AF||Autofocus mode with 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:
|FULL||Full range of focusing distances.|
|5 m - ∞||Range of focusing distances suitable for shooting distant subjects.|
|10 m - ∞||Range of focusing distances suitable for shooting distant subjects.|
By setting the suitable focusing distance range, the actual autofocusing time can be shorter.
The lens does 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 1/500 second (at focal length of 500 mm) which may require in some cases increasing the ISO setting and will lead to noisy images.
- The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3400, D5000-D5600 SLR cameras.
