Placed under the Art category, this large-aperture standard lens with an
angle of view equivalent to 45mm on a 35mm camera is a superb go-to
lens for artistic photography on an APS-C format digital SLR. Offering
the bright F1.4 aperture and an angle of view extremely close to that of
human vision, this lens is ideal for many different types of
photography. Equipped with the latest in lens technology, the 30mm 1.4
lens boasts a Hyper Sonic Motor (HSM), Super Multi-Layer Coating and a
design featuring Thermally Stable Composite Material (TSC). The HSM
ensures quiet, accurate and high-speed autofocus; the Super Multi-Layer
Coating reduces flare and ghosting, while the TSC reduces expansion and
contraction of the internal lens barrel. A rear focus system prevents
focus-dependent variation in aberration, making high-level image quality
possible throughout the entire image. With their unchanging barrel
length, these lenses also enhance balance and stability for the
photographer. An optimized autofocus achieves a smoother focusing. The
30mm 1.4 has a minimum focusing distance of 11.8in and a maximum
magnification ratio of 1:6.8. A 9 blade rounded diaphragm creates
beautiful bokeh. Under the Global Vision standard, every lens will be
tested before shipping using the Sigma A1 MTF system to ensure the
highest degree of quality possible.
