Pentax Debuts 90mm Macro Lens

Medium-telephoto lens designed for 645D SLR medium format camera

CORPORATION (PENTAX), today announces the HD PENTAX D FA 645 Macro 90mm
F2.8 ED AW SR interchangeable medium-telephoto lens, designed for the
company’s 645D SLR medium format camera. When mounted on a PENTAX 645D,
this lens offers a 35mm equivalent focal length of approximately 71mm
(or approximately 56mm when mounted on a PENTAX 645 film-format camera
body). By incorporating two ED (extra-low dispersion) elements and one
glass-molded aspherical element in its optics, the lens assures high
resolution image reproduction over the entire image field, while
effectively minimizing chromatic aberration – a problem commonly
associated with fast lenses.

“The new HD PENTAX D FA 645 90mm
lens was designed exclusively for our 645D medium-format SLR cameras and
it marks an important expansion in our medium-format lens lineup,”
explains John Carlson, Sr. Manager of Sales and Marketing, PENTAX. “This
versatile medium telephoto lens is ideal not only for portrait and
macro photography, but scenic and still life photography as well.”

FA 645 90mm lens offers macro photography at a maximum magnification of
0.5X. In close-up applications, its floating mechanism effectively
compensates for the curvature of the field to assure sharp, well-defined

PENTAX D FA 645 90mm HD Lens Features
New HD Coating and Aero Bright Coating to optimize light transmittance and minimize reflection
lens is treated with HD Coating*, a newly developed, high grade
multi-layer lens coating , which offers higher light transmittance with
reduced reflection, to deliver sharp, clear images free of flare and
ghosting, even under demanding lighting conditions such as backlight. By
coupling this coating with the PENTAX-exclusive, high grade Aero Bright
Coating,** this lens optimizes light transmittance while minimizing

PENTAX-original, lens-based SR mechanism
This is
the first lens to incorporate the PENTAX-innovated SR (Shake Reduction)
mechanism within the lens barrel. Since this mechanism effectively
compensates for camera shake up to approximately 3.5 shutter steps, the
user is assured of sharp, blur-free images even under conditions prone
to camera shake, such as when handholding the camera in poorly lit
locations without flash illumination, or when photographing sunset

Dustproof, weather-resistant construction
of the AW (All Weather) series, this lens features a dependable
dustproof and weather-resistant construction with 11 special seals to
effectively prevent the intrusion of dust and water into the lens
interior. By mounting it on a PENTAX 645D camera body, the user is
assured of a durable, reliable imaging system that performs superbly in
demanding outdoor conditions such as rain, mist, or in locations prone
to water splashes or spray.

New exterior design signifying HD series
inheriting traditional design features of PENTAX medium-format lenses,
such as a twill-patterned focus ring and metal rings, this lens features
a red anodized ring on the front of the focus ring to signify the new
HD PENTAX lens series and enhance its exclusive appearance.

Other features:
• Quick-Shift Focus system for instant switching to manual focus
operation after the subject is captured in focus by the camera’s AF
• SP (Super Protect) coating applied to the front surface
of the lens to effectively repel water and grease and to allow dust and
stains to be easily wiped from the front lens element.
• Rounded
diaphragm blades deliver precise control while producing a smooth,
beautiful bokeh (out-of-focus rendition), minimizing the streaking
effect of point light sources
