This Sigma 150-500mm f/5-6.3 DG OS HSM APO Lens is an ultra
telephoto zoom lens ideal for nature, wildlife, or sports photography.
This zoom range translates into an equivalent range of 225-750mm when
used with a Nikon digital SLR camera.
The OS (Optical Stabilizer) system minimizes image blur caused
by camera shake, and offers the equivalent of shooting at a shutter
speed 3-4 stops faster. This allows handheld telephoto zoom shooting
even in poorly lit conditions.
The use of the OS (Optical Stabilizer) system, HSM (Hyper Sonic Motor), APO apochromatic design, three elements of SLD (Special Low Dispersion)
glass, and multicoated optics all enable this lens to provide a high
level of performance throughout its entire zoom range, as well as
versatility. A rear focus system insures quick, convenient manual focus
and a non-rotating front barrel.
The improved DG lens design
corrects for various aberrations. This lens is specially coated to get
the best color balance, while cutting down on ghosting caused by
reflections from the digital image sensor. The lens provides the utmost
correction against lateral chromatic aberration, which is a serious
problem for digital SLR cameras.
By adding the optional Sigma
APO teleconverter, you can use this lens as a 210-700mm f/7-9 manual
focus ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a
300-1000mm f/10-13 manual focus ultra-telephoto zoom lens with a 2X
teleconverter.
Note!
HSM lenses, while able to manually focus with all Nikon F-mount
cameras, will not autofocus with certain older film AF cameras. This is
the same limitation as with Nikon's own AF-S lenses. Incompatible
models are: N60, N55, N8008/s, N6006, N5005, N4004 & N2020.

The OS system uses two sensors inside the lens to detect vertical and
horizontal
movement of the camera. It works by moving an optical image stabilizing
lens group, to effectively compensate for camera shake. It
automatically detects movement of the camera and compensates for camera
shake when shooting a moving subject such as motor sports.

The HSM (Hyper Sonic Motor) system ensures quiet and high-speed auto focusing with full time manual focus override.
- •
Three Special Low Dispersion (SLD) elements provide excellent correction for chromatic aberration.
- •
Super Multi Layer (SML) coating reduces ghost and flare.
