PENTAX
Markets a Compact 18mm~35mm
Zoom Lens for Its 35mm-Format Autofocus SLR Cameras
PENTAX
Corporation is proud to announce the marketing in September of the smc
PENTAX-FA J Zoom 18mm~35mm F4~F5.6 AL for use with PENTAX 35mm-format
autofocus SLR cameras. Featuring an ultra-wide 100-degree angle of view at
the 18mm focal length, this compact interchangeable zoom lens produces
high-quality images with minimal aberration, thanks to the incorporation of
an aspherical lens element.
Featuring a
simple, functional design without an aperture ring, this compact,
high-performance zoom lens measures only 72 millimeters (2.8 inches) in
diameter and 68.5 millimeters (2.7 inches) in length and weighs a mere 190
grams (6.7 ounces). It also features an angle-of-view coverage between 63
and 100 degrees and a minimum focusing distance of 0.28 meters (0.92 feet)
for a maximum magnification of 0.18 times. It comes equipped with a lens
hood to cut off excessive light and minimize flare and ghost images.
When mounted on
the new PENTAX *ist D digital SLR camera, this zoom lens offers focal
lengths equivalent to 27.5mm~53.5mm in the 35mm format to cover wide-angle
to standard ranges.

PENTAX
Develops the New DA Series
of Interchangeable Lenses for Its Digital SLR Cameras
PENTAX
Corporation is proud to announce that it is currently in the final stage of
development of the compact, high-performance smc PENTAX-DA series of
interchangeable lenses, exclusively designed for use with PENTAX digital SLR
cameras.
The image circle
in the DA-series lenses is designed to perfectly match the size of the CCD
(23.5mm x 15.7mm) incorporated in PENTAX’s digital SLRs, optimizing the
performance of these cameras. The new design also contributes to a drastic
reduction in size, weight and production cost, compared to 35mm-format
counterparts with similar specifications.
As the first
model of the new DA series, PENTAX plans to market the smc PENTAX-DA Zoom
16mm~45mm F4 ED AL (tentative name, equivalent to 24.5mm~69mm in the 35mm
format; marketing date to be announced), which features a three-times zoom
ratio with focal lengths covering ultra-wide to moderate-telephoto ranges
when mounted on the new PENTAX *ist D digital SLR camera. It also
incorporates an Extra-low Dispersion (ED) glass lens element and two
aspherical lens elements for true-to-life image reproduction and size
reduction.
Its simple,
functional design, coupled with the elimination of an aperture ring,
considerably improves the camera’s operability.
