Description:
The Zuiko Digital ED 14-35mm f2.0 SWD
lens (equivalent to 28mm to 70mm) is the world's first standard zoom lens to
feature a large f2.0 aperture. Boasting industry-leading imaging performance,
this lens is a worthy addition to the Olympus Super High Grade (SHG) series of
lenses. Together with the ED 7-14mm f4.0, ED 35-100mm f2.0 and ED 90-250mm f2.8
lenses, this lens completes Olympus' series of professional zoom lenses with
fixed F-values.
The flagship of the Zuiko Digital series, this lens was developed to meet the
requirements of the most demanding professionals. It includes reliable splash-
and dust-proofing, Olympus' exclusive SWD-driven ultra-fast AF system, a
mechanically interlocked manual focusing mechanism and a large, flower-shaped
hood with a polarization filter control window.
With its unique f2.0 aperture providing bright viewing with a sharp subject and
a soft blurring of the background, this lens epitomizes the versatility, power
and creative freedom made possible by the Four Thirds System and is ideal for
almost any application -- from landscapes and portraits to indoor shooting and
photojournalism.
Supersonic Wave Drive Technology
Olympus-proprietary SWD technology has enabled an ultra-fast, whisper-quiet,
high-precision AF system. Two compact, high-powered Supersonic Wave Drive
devices power autofocus at an ultra-high speed by exciting unique elliptical
oscillations, while an ultra-compact 5.3mm x 4.3mm optical encoder detects and
controls the lens drive position using direct rotation detection without
reduction gear. This enables it to achieve a level of precision that's accurate
to 5 microns (5/1000 mm). When used in combination with the new E-3, which
offers improved AF computation and lens-body communication rates, the SWD motors
provide the fastest focusing speed of approximately 170 ms (0.17 seconds).
