The Sigma 105mm f2.8 EX DG OS HSM Macro Lens for Nikon is a large aperture medium telephoto macro lens offering advanced performance for close-up photography. Sigma’s own proprietary OS (Optical Stabilizer) system enables handheld close-up photography. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.
Sigma 105mm f2.8 EXDG OSHSM Macro Lens for Nikon Features:
Telephoto prime is designed for full-frame Nikon F-mount cameras, however it is also suitable for APS-C models where it will provide a 168mm equivalent focal length.
Bright f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
Ideal for macro shooting, this lens offers a life-size 1:1 maximum magnification along with a minimum focusing distance of 1' to suit working with close-up subjects.
Two Special Low Dispersion (SLD) elements help to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
Hyper Sonic Motor (HSM), along with an internal focusing design, realizes quick and quiet autofocus performance as well as full-time manual focus override.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range.
Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
