Sigma's third generation 12-24mm f/4 DG HSM Art Lens, available here
with a Nikon F Mount, refines their ultra-wide arena and delivers an
image with little distortion and with a high resolution for crisp photos
with a modern full-frame digital image sensor. A member of Sigma's Art
series, it boasts high image quality which is helped out by the use of
FLD and aspherical elements, including an 80mm large-diameter molded
glasses aspherical lens, that minimizes aberrations and distortion.
Furthermore, it uses a Super Multi-Layer coating that minimizes flare
Benefitting handling, the 12-24mm is equipped with a Hyper Sonic AF
motor with an optimized algorithm for speed and accuracy. The lens also
offers a large focusing ring with full-time manual override settings for
quickly making adjustments. A rounded 9-blade diaphragm improves image
quality by helping create smooth bokeh while the lens is constructed
from a lightweight and durable thermally-stable composite. Also, the
12-24mm has a brass bayonet lens mount and is dust- and splash-proof.
And, it is fully compatible with Sigma's USB Dock.
