hypersonic focus motor with full-time manual focus override, the lens uses a 9-blade diaphragm for attractive background blur, and has a minimum focus distance of 85cm. It comes with a lens hood adapter for ASP-C/DX users that extends the length of the hood to give more effective shading, and will be available in mounts for Canon, Nikon, Pentax, Sigma and Sony SLRs.
For digital cameras with an APS-C size image sensor, a dedicated hood adapter, which expands the length of the lens hood, is supplied and enables the hood to block out extraneous light more effectively

Sigma's New 85mm F1.4 EX DG HSM lens is a large aperture medium telephoto lens optimized for use with digital SLR cameras and is especially ideal for portrait and low light photography.

It is equipped with a rear focus system that minimized fluctuation of aberration caused by focusing and the Super Multi Layer Coating reduces flare and ghosting even in backlight photography.
HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus capability and the round 9 blade diaphragm creates pleasant out-of-focus highlights.
HSM means this lens will autofocus on Nikon D40/D40x,
Nikon D60, Nikon D3000,
Nikon D3100 and the
Nikon D5000 DX Cameras
It comes with a Petal-type hood to block out extraneous light. For digital cameras with an APS-C size image sensor, a dedicated hood adapter, which expands the length of the lens hood is supplied and enables the hood to block out extraneous light more effectively.
An f/1.4 lens is not usually as efficient as the same manufacture's f/1.8 or f/2
lenses, even when both are stopped down to f/5.6. the lens with the wider
aperture is heaver and more expensive, so don't choose it as your standard
unless you are planning a great deal of photography poor light conditions.
There' plenty of reasons for using a wide aperture, but avoid buying a lens with
an aperture wider than you need.

Reviews
SLR
Gear
Sigma has produced an excellent
lens here: as sharp as any of
its contemporaries, even wide
open at ?/1.4. As well, the lens
offers remarkable tolerance to
chromatic aberration, marred
only by the presence of
longitudinal chromatic
aberration that seems to be
common with fast glass.
Distortion and corner shading
are also excellent. With the
Sigma 85mm ?/1.4 producing
results on par with its
competitors, it's easy to
recommend, especially given the
cost savings that will result.
However, its build quality isn't
as strong as some, so how you
use a lens in this category, and
what environments you'll take it
into, should be a factor in your
purchasing decision.
