Ricoh GXR Interchangeable Unit Camera Gets Official Ricoh GXR Camera Boasts Lens Units with Sealed Integrated Matched Sensors

Ricoh has now gone official concerning its new Ricoh GXR Interchangeable
Unit Camera which, thanks to utilising innovative interchangeable unit
camera systems, which comprise of lens, image sensor, and image
processing engine housed within single units (thus leaving the camera
sensor free), which will see not only ideal matching of lens and sensor
types that are, assumedly, perfectly calibrated but which will wholly
circumvent issues such as dust and other foreign particles impacting on
imagery.
Billed as being the world s smallest and lightest digital camera
featuring interchangeable lenses, the Ricoh GXR, which Ricoh tout as
serving to pioneer a �new realm of photography offers the following
main, key features:
Ideal form for an interchangeable lens camera: The interchangeable unit
camera system
By integrating lens, image sensor, and image processing engine into a
single optimized unit, we were able to created a compact camera with
interchangeable lenses.
The adoption of this new system has made it possible to achieve both
pocket size for go-anywhere portability and the highest image quality
for every photographic situation and subject.
Since the image sensor is not exposed when lenses are changed, the
camera's structure makes it inherently difficult for dirt and dust to
get inside.
Putting image processing engines in both the body and the camera units,
our focus was on achieving the highest image quality.
Elegant design
For the exterior, we utilized die cast magnesium, which has a strong
track record in the GR series, and we covered the surface with a
corrosion-resistant pear-skin coating. The end result is a body with
superior levels of durability, light weight, and feel in hand.
Building on the operation control designs of the GR series and GX
series, the GXR has several types of customizable buttons as well as the
new DIRECT button, which the photographer can use to see many current
settings at a glance. Sophisticated shooting settings can now be made
faster than ever before.
The directional pad, the three My Settings, the ADJ.lever, and the
function buttons all contribute to the even greater operability achieved
by the GXR.
The grip form allows the GXR to be firmly held despite its small size,
and the suitably yielding rubber material on the grip surface enables
the camera to feel like an integral part of the hand.
Even greater power of expression
The automatic exposure modes include program shift mode, shutter
priority mode, and aperture priority mode.
Picture settings can be customized with nine setting levels for easy
creation of a diverse ย range of images.
ISO3200 facilitates shooting in low light conditions.
Enhanced rapid shooting capabilities help capture fleeting shutter chances
The Pre-AF function accelerates focusing speed by adjusting the focus to
match subject movement.
The full press snap function shoots at a preset distance for a one-push
full-press of the shutter-release button.
When shooting subjects up close, the camera automatically switches to
macro mode so macro photography can now be enjoyed without having to
worry about switching modes.(Auto macro setting)
High-definition 3.0-inch 920,000-dot VGA LCD picture display
The high-resolution LCD picture display provides a wide viewing angle
and high contrast. The screen has a fluorine coat to prevent soiling, a
hard coat to prevent scratches, and an anti-reflection coat to give
excellent visibility even outdoors in bright sunshine.
With 100% sRGB coverage for color reproduction, the picture display
vividly reproduces image colors.
Wide range of functions
Tilt indicator utilizing an acceleration sensor.
Three grid guides useful for framing images while shooting.
Image flag function to enable the quick display of specific images from
among those in the camera. Up to 20 images can be flagged.
The new DIRECT screen enabling current settings to be displayed and changed.
Features of the GR LENS A12 50 mm F2.5 MACRO camera unit
This camera unit uses a 23.6 mmร—15.7 mm (APS-C size) CMOS sensor with
approximately 12.30 megapixels. In combination with image processing
engine GR ENGINE III, it achieves high-image-quality photography with
high definition, low noise, and smooth tonal gradations.
A newly developed GR LENS with an 8-group, 9-element configuration
(aspherical lens: 1 element, two surfaces) is featured. Representing a
further advancement in the GR tradition of high image quality, the lens
thoroughly corrects for various types of aberrations. Despite the
compact size, it is also a full-fledged macro lens with a floating lens
structure. At shooting distances from infinity down to the 1/2x maximum
magnification macro range, it achieves strong imaging power all the way
to the edge of the frame. In addition, the low level of vignetting means
that the photographer can enjoy rich and genuine bokeh effects.
The manual focus ring is perfect for use in macro photography as it
makes highly precise focusing possible. It can also be used to make fine
manual adjustments to the focus after autofocus is done.
Features of the RICOH LENS S10 24-72 mm F2.5-4.4 VC camera unit
This camera unit uses a 10.00 megapixel 1/1.7-inch CCD sensor boasting
high-sensitivity capabilities enhanced through the adoption of an new
process. In combination with advanced image processing engine Smooth
Imaging Engine IV, it achieves high-image-quality photography with high
definition and low noise.
The lens is a 24 mm to 72 mm high-performance 3x wide-angle zoom with
superior usability. Utilizing a 7-group, 11-element configuration
(aspherical lens: 4 elements, 4 surfaces) that includes special
low-dispersion lenses, this lens achieves high dimensions of both
compactness and imaging power.
A camera shake correction function (image-sensor-shift type) is used to
reduce hand- motion blur.
The self-retaining lens cap has been a popular GX series option, and a
GXR version is available as option LC-2.
New options enhance series expandability
Two soft cases, one for each camera unit.
The GXR can use the GR DIGITAL III external flash (GF-1), which can do
TTL flash using auxiliary flash.
Convenient for shooting in bright outdoor situations, the newly
developed 920,000-dot- equivalent high-definition LCD viewfinder is
removable and can be tilted up to 90 degrees. With a 100% field of view,
it displays information in the same way as the picture display, thus
enabling the photographer to shoot in a film camera style.
Functions expanded using firmware
Function-enhancing firmware releases for the GR DIGITAL series have
proved very popular, and this practice will be continued for the GXR. By
updating their firmware, GXR owners will be able to use the latest
functions.
As yet there s now word concerning either the Ricoh GXR s release date
(it s set for 2010, but we know little more than that) or pricing but
those who are looking for an extensive and particularly insightful
preview of the Ricoh GXR will undoubtedly find DPPreview s hand s on of
great interest.
