Sigma 70-300mm Lenses for Nikon

Sigma has added a built-in motor to the 70-300mm f/4-5.6 APO DG Macro and 70-300mm f/4-5.6 DG Macro lenses to make them compatible with Nikon DSLRs. The Nikon D40, D40x and D60 cameras cannot fully support the original Nikon lenses, as there is no AF motor built into these cameras, therefore they require a motor built into the lens to achieve autofocus. The inclusion of the built-in motor in these two new lenses allows autofocus with all Nikon cameras. The 70-300mm f/4-5.6 APO DG Macro lens costs £199.99, and the 70-300mm f/4-5.6 DG Macro £149.99.

Incorporation of a built-in motor allows autofocus with all Nikon cameras

The Sigma Corporation is pleased to announce the launch of the new APO 70-300mm F4-5.6 DG Macro for Nikon and 70-300mm F4-5.6 DG Macro for Nikon. The Nikon D40, D40x and D60 cameras cannot fully support the original Nikon lenses, as there is no AF motor built into these cameras, therefore they require a motor built into the lens to achieve autofocus. Many people are unaware of this until they have purchased their new Nikon D40 or D40x. The inclusion of the built-in motor in these two new lenses allows autofocus with all Nikon cameras.

Three pieces of SLD (Special Low Dispersion) glass in the front lens group and another two in the rear group offer excellent correction of chromatic aberration. High optical performance is demonstrated throughout the entire zoom range.

Both the DG and APO DG lenses incorporate a macro feature with maximum magnification 1:2 at the 300mm focal length making it suitable for many types of photography.

The new multi layer lens coating reduces flare and ghost, which is a common problem with digital cameras and also creates an optimum colour balance.

A convenient magnification scale showing focusing distances and reproduction ratios is engraved on the lens barrel. A versatile telephoto zoom lens that is ideal for portraits, sports and nature photography, and all types of imaging needing both telephoto and close-up capabilities.
