Ricoh's unrivaled GR Lens enters the digital age
|
 |
The texture of skin. The details of a single
strand of hair. All is revealed in a subject standing out against
a blurred background.
1/68sec, F3.5, ISO64, EV+0.3, (Full-size photo; no trimming) |
 |
Exceptional resolution and low distortion in a single lens
unit
|
Superb image resolution that clearly
captures individual hairs. Crisp image quality even in the periphery.
These are the proud hallmarks of Ricoh's highly renowned GR
Lens, which is breathing new life into digital photography.
As illustrated by the MTF curves below, the GR Lens (F2.4, f=5.9mm,
equivalent to 28mm focal length on 35mm film camera) compensates
for various aberrations, as well as weaker light in the periphery
to deliver high-resolution, high-contrast reproduction over
the entire image. This exceptional optical performance is ideal
for pan-focus, wide-angle photos and empowers users in all shooting
environments by providing sharp images with natural color even
when the aperture is fully open. With its standout performance
and unique personality, this new GR Lens is worthy of inheriting
the GR name. |

Retractable 5-group 6-lens unit showcases original Ricoh
technology
|
 The
GR Lens fully compensates for aberrations throughout the wide
28mm field of view by employing six high-quality optical glass
lenses in five groups with a special low dispersion lens and
two molded aspherical lenses. Multi-coated lens surfaces help
direct all wavelengths toward the image sensor for maximum lens
brightness, and a large maximum aperture of F2.4 enabled Ricoh
to strike a fine balance between large lens diameter and compact
dimensions. The original, space-saving design of this retracting
lens system combines with a micro-precision drive to enable
housing of the high-performance 28mm equivalent lens unit within
a slender 25mm body. |
Beautiful blurred backgrounds through seven aperture blades
|
 Fine-tuning
of the aperture between F2.4 and F9 settings is possible in
1/3EV step increments, allowing photographers to adjust depth
of field and achieve beautiful blurred backgrounds whenever
desired. The quality of blurred backgrounds is especially high
because seven aperture blades (an odd number) form a nearly
circular lens iris not only when the aperture is fully open,
but also when the aperture is nearly closed. |
