GARANZIA UFFICIALE FOWA 4 ANNI
1. Exceptional imaging performance made possible by the latest optical design technologies
The lens incorporates one ED (Extra-low Dispersion) glass optical element and two Anomalous Dispersion
glass optical elements to compensate for various aberrations and minimize the generation of the
unwanted purple fringe effect. This is coupled with the high-grade, multi-layer HD (High Definition)
Coating, which reduces average reflectance in the visible ray spectrum to less than 50 percent compared
to conventional models, and the innovative FREE (Fixed Rear Element Extension) focusing system. All
together, these technologies effectively reduce the generation of flare and ghost images to a minimum
over the entire focus range — from minimum focusing distance to infinity — and deliver clear, high-quality
images. The lens also provides lifesize magnification in close-range shooting to capture dramatic,
fine-detailed close-up images.
2. Dustproof, weather-resistant AW construction for exceptional outdoor shooting reliability
Ready for diverse outdoor shooting conditions, the lens features dustproof, weather-resistant AW (All
Weather) construction for the first time in a PENTAX macro lens. This dependable construction prevents
the intrusion of dust and moisture into the interior, using six sealing parts to optimize airtight performance.
When mounted on a dustproof, weather-resistant PENTAX digital SLR camera body, it creates a
highly dependable, durable imaging system that performs superbly in demanding shooting settings —in
rain or mist, or in locations prone to splashing or spraying water.
3. Exclusive exterior design and outstanding operability
The lens has an attractive, stylish appearance, thanks to its metallic exterior parts meticulously machined
from high-grade aluminum. Its focus ring features the PENTAX-original Quick-Shift Focus System, which
allows the photographer to instantly shift the focus mode from auto to manual after the subject has
been captured in focus by the camera’s autofocus system. This single-action operation assures a smooth,
comfortable focus-mode switching maneuver during manual-focus shooting, for dramatically improved
operability.
4. Compact, lightweight design for superb maneuverability
Despite the greatly improved imaging power made possible by the new optical design and outstanding
dust-proof, weather-resistant performance, the lens is designed to be nearly as compact and lightweight
as the smc PENTAX-D FA MACRO 100mm F2.8 WR (launched in December 2009), assuring outstanding
maneuverability.
5. Other features
・A working distance of 13 centimeters (at life-size magnification) to facilitate the shooting of
unapproachable subjects, such as insects
・Individual serial number assigned to each lens: black models starting at 0000001,
the silver model at 1000001
・Circular diaphragm to produce a natural, beautiful bokeh (defocus) effect from open aperture
to F5.6, while minimizing the streaking effect of point light sources
・SP（Super Protect）Coating applied to the front optical element, to keep the front surface
free of dust or stains
