Peak 85mm F1.4 optical performance that more than satisfies the stringent
standards of the Art line.
Portrait photographers demand the attractive bokeh effect that large-diameter lenses offer, as
well as outstanding resolution. Fulfilling the exacting standards of the Art line, the SIGMA 85mm
F1.4 DG HSM | Art delivers both of these elements at the highest level. The bokeh effect is so
precise, you can focus on the pupil of the subject’s eye while blurring the eyelashes. Adding to the
effect, the area in focus is extremely high-resolution while the bokeh area is very attractive in
appearance. The SIGMA 85mm F1.4 DG HSM | Art incorporates 14 lens elements in 12 groups, a
remarkable structure that helps the lens deliver ultra-high-resolution. This lens is therefore an
excellent match for full-frame DSLRs offering 50-megapixel or higher resolution.

A design that prioritizes optical performance—without compromise.
● Outstanding resolving power and minimized chromatic aberrations help
make this the ultimate lens for portraits.
To create a top-performing 85mm F1.4 lens, SIGMA leveraged its latest innovations in
design and materials. The result is the ultimate lens for portraits. By taking chromatic
aberrations to the absolute minimum, this lens offers performance that goes beyond,
including incredibly sharp resolution and a beautiful bokeh effect.
● Image quality perfect for ultra-high-megapixel digital cameras
Ultra-high-megapixel full-frame DSLRs offering 50-megapixel or higher resolution are now
available, and nothing will bring out the performance potential of these cameras better
than the fundamental performance of the lens. The SIGMA 85mm F1.4 DG HSM | Art
incorporates two elements made of SLD (Special Low Dispersion Glass) and one element
with a high rate of anomalous partial dispersion and a high index of refraction. These
features help ensure a clear image throughout the plane. The optical system also minimizes
