Design and Features
For information on history of Sigma and development of Sigma Global Vision line please refer to the article dedicated to Sigma 35mm F/1.4 DG HSM | A.
Improved version of Sigma 85mm F/1.4 EX DG HSM with new optical formula and modern barrel design, moisture resistant mount, fluorine coating on front and rear optical elements. The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance, and the updated AF algorithm helps ensure nimble autofocus performance. The lens for the Nikon camera includes the electromagnetic diaphragm mechanism.
The lens barrel is heavy, made of high-quality plastic (TSC). The lens mount is metallic, water-resistant. Please refer to the article dedicated to Sigma 35mm F/1.4 DG HSM | A for more information about TSC. In terms of build quality and design Sigma Global Vision line is a new direction for the company: cosmetically the lens differs from the earlier models and looks attractive. The focusing ring is wide, rubberized and finely-ribbed in order to provide a good grip and to prevent slippage of the fingers.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
The lens uses front filters with standard size of 86 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
A fluorine coating has been applied to the outer surfaces of the front and rear lens elements to repel particles of dust, water or oil drops for easier cleaning of the lens surfaces.
The lens is equipped with ultrasonic motor, the autofocus is virtually silent and fast.
The lens is compatible with Sigma USB dock, an optional accessory which allows to connect the lens to a computer and customize its operation via Sigma Optimization Pro software. The customization for this lens includes updates of firmware via the Internet and autofocus microadjustments for 4 shooting distances.
Sigma also offers paid Mount Conversion Service (MCS) for this lens. With MCS, the mount of the lens can be converted to Canon EF, Nikon F or Sigma SA. Teleconverters, USB docks and other accessories for this lens are not eligible for MCS.
Aspherical elements (ASPH, XA, XGM) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
