Olympus Zuiko 7mm - 14mm f/4.0 E-ED Digital Zoom
Lens for the E Digital SLR System
"Designed for
Digital" Lens Based on Four Thirds System -
Super-Wide-Angle 2x Zoom Performance with a
Minimum Wide-Angle starting focal length of
7mm
With a minimum wide-angle starting focal
length of 7mm (equivalent to 14mm on a 35mm
film camera), the 114-degree picture angle
provided by this product is the widest in
the world (NOTE) for a zoom lens designed
for use with digital cameras. As a
super-wide-angle lens, it allows the
photographer to create out-of-the-ordinary
images by emphasizing depth of field and
perspective. Because it is designed
specifically for use with digital cameras,
this lens ensures stable imaging quality
right out the periphery of the image.
Working Distance of Just 10cm for Enhanced
Photographic Possibilities
The inner focusing system features a newly
developed "floating" mechanism that ensures
excellent image quality at all ranges from
infinity to extreme close-up. With a minimum
working distance (NOTE) of just 10cm, the
lens allows the photographer to work
extremely close to the subject, which is
essential to create images with enhanced
perspective
Large-Aperture Aspherical Lens - World's
First ED Molded Glass Aspherical Lens
Elements
The new lens incorporates two molded glass
aspherical lens elements for effective
correction of the distortion and astigmatism
commonly associated with super-wide-angle
lenses. Distortion is minimal, even when
shooting close to the subject, allowing the
lens to produce sharp images that precisely
reflect the photographer's intentions in all
types of photography. Large-aperture concave
lens elements that are aspherical on both
sides play a particularly important role in
the correction of distortion and curvature.
This lens also features the world's first
(NOTE) two-sided aspherical ED lens
elements. In addition to color correction,
these also allow the elimination of coma
flare on the periphery of images
Dual Super ED and ED Lens Elements Used to
Minimize Chromatic Aberration
Super-wide-angle lenses are prone to
chromatic aberration. The Zuiko Digital
ED7-14mm F4.0 incorporates two ED lens
elements, and its ED lens group also
includes two Super ED lens elements with
color dispersion characteristics similar to
those of fluorite. Theseallow the lens to
suppress color aberrations that cannot be
fully corrected with conventional optical
glass. The result is optimal resolution and
contrast.
New Multi-Coating Process to Reduce Ghosting
and Flaring
Olympus has used a newly developed
multi-coating process to minimize
reflections across a wide range of wave
lengths. This feature minimizes the ghosting
and flaring that commonly affect wide-angle
lenses.
Dust and Water Droplet Resistance for
Enhanced Reliability
Exterior parts of the lens have been sealed
to provide enhanced protection against dust
and water droplets, ensuring reliable
performance even under the tough shooting
conditions experienced by pro photographers. |
