Product Description
The AT-X 840 AF D has been improved and updated with a smooth and quick internal focusing system. This means that the all-metal inner barrel that houses the heaviest glass elements does not have to rotate when the lens focuses, making it much faster than the previous models.
- • Optimized for use with digital SLR cameras, with an equivalent range of approx. 128-640mm.
- • Built-in tripod collar makes for a well-balanced camera/lens combination when using a tripod or monopod.
- • The lens hood with the a PL Assist spring loaded thumb wheel allows a circular polarizer or special effects filter to be rotated while the lens hood is in place.
