Sigma APO 500mm F4.5 EX DG (Sony)

Prime super telephoto 500mm f/4.5 lens is designed for FX-format Nikon F-mount DSLRs, and can also be used on DX models where it provides a 750mm equivalent focal length.

Sporting an apochromatic design, two Extraordinary Low Dispersion (ELD) glass elements are used to reduce chromatic aberrations and color fringing throughout the aperture range in order to produce greater clarity and color fidelity.

A Super Multi-Layer Coating has been applied to minimize ghosting and flare when working in strong lighting conditions.

The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. Internal focusing design limits the overall length of the lens during operation for more intuitive, controlled handling as well as faster performance.

A manual focus clutch lets you slide the focusing ring back or forth to quickly switch between manual and autofocus modes.

Nine-blade diaphragm contributes to a pleasing bokeh quality when working with selective focus and shallow depth of field techniques.

A fixed, rotating tripod collar offers increased stability when working from a tripod as well as intuitive switching between horizontal and vertical shooting orientations.

A rear drop-in slot enables the use of 46mm drop-in filters via the included filter holder, and both UV and circular polarizer filters are included.

Compatible with optional APO Tele Converters to further extend the reach of this super telephoto lens.
