Ricoh GXR Brochure & Specs

The lens configuration has 8 groups and 9 elements. Making good use of the new
system's advantage of not having to accommodate back focal length, we were able
to design the refractive capabilities of each element in a more efficient and practi-
cal manner than is possible for SLR interchangeable lenses. Partly thanks to the
use of a large-diameter aspherical element, this lens achieves a superior level of
edge-to-edge resolution and image quality unimaginable for its small size.
In addition, there is little vignetting so richly luminous, natural-form bokeh
extends to the edge. The floating structure corrects various types of aberrations
that tend to occur in close-up photography. Even at the minimum shooting
distance, this lens gives excellent definition and sharpness worthy of the GR LENS
name.
*There is a built-in extendable hood.
The CMOS sensor boasts 23.6 mm × 15.7 mm size for rich bokeh and approxi-
mately 12.30 million effective pixels for superior resolution. Supporting the excep-
tional optical performance of the GR LENS, this image sensor enables the photog-
rapher to obtain both crisp details and refined bokeh, and the wide dynamic range
gives rich tonal gradations. The result is high image quality that demands printing
in large format.
Close-up photography at a maximum magnification of 1/2x is possible, with the
minimum shooting distance approximately 7 cm from the front of the lens. A
manual focus ring is also provided. If the body focus ring setting selected is
AF+MF, after the AF focusing is done it is possible to turn the focus ring to make
fine adjustments to the focus.
Enjoy shooting HD movies. Image size is 1280×720, aspect ratio 16:9, and frame
rate 24 frames/sec. Utilizing the high sensitivity (maximum ISO 3200) and the
beautiful bokeh made possible by the F2.5 aperture and the large image sensor, it
is possible to create impressive movies with a different feel than those of standard
video cameras. The GXR body has an HDMI connector so for large-screen movie
viewing it can be connected to TVs supporting HDMI.
*HDMI cable sold separately.
Paired with a 23.6 mm×15.7 mm image sensor,
this GR LENS is a standard macro boasting superb definition and refined bokeh.
