Ricoh GR DIGITAL IV Digital Camera Announced

GR Digital IV upgrades Ricoh's premium range - Ricoh has announced a new compact camera to sit within its premium GR series, the GR DIGITAL IV succeeds the GR Digital III with enhanced Quick Shooting capability and image quality.The new GR Digital IV features a new image engine along with a refined optical filter, which Ricoh promises is the highest image quality in the history of the GR series.

AF speed and accuracy has been improved with the introduction of a new Hybrid AF system. The camera is equipped with Ricoh's independently developed external AF sensor which has a maximum of 190 AF points.

Thanks to the new system, Ricoh claims that the AF focusing time is now as short as 0.2 seconds, half that of the GR Digital III. Algorithm refinements have also been made to improve AF speed for macro shots.

As with the GR Digital III, the IV is capable of shooting raw images in the DNG format along with standard JPEGs.

Image processor

A new image processing engine, the GR Engine IV, promises to enhance colour reproduction and colour noise reduction when taking high-sensitivity photographs.

The 28mm (equivalent) f/1.9 fixed length GR lens is accompanied by a 10 million pixel 1/1.7-inch CCD sensor which has been designed to reduce chromatic aberration and distortion.

A first for the GR Digital Series, the IV features image-sensor shift image stabilisation function, which is equivalent to a shutter speed increase of up to 3.2 stops.

On the rear of the camera is a new high-brightness 3 inch 1.23million dot VGA LCD monitor which is now equipped with automatic brightness function and is approximately 1.7 times brighter than the GR Digital III.

Shooting functions include dynamic range compensation to minimise the effects of blown highlights and dense shadows. Auto Bracket has been enhanced, in addition to the conventional exposure and white balance, Contrast Bracket Setting and Dynamic Range Compensation have been newly added.

Interval Composite mode replaces and combines high brightness pixels in images of the night sky taken at fixed intervals. According to Ricoh this makes it possible to shoot "distinctive landscape pictures that show the trails of light left by the stars."

Creative effects

New film effect modes include Positive Film and Bleach Bypass and join existing High Contrast black and white and Cross Process modes, each of which can be used in Auto and P/A/S/M modes. Multiple exposure shooting and bulb exposure functions have also been included.

The electronic level function has been improved to have the ability to detect not only the horizontal direction, but also the tilt direction as well.

The Ricoh GR Digital IV UK price is £499.99 RRP and will be available from mid- October in black or limited edition white.

Ricoh M-mount GXR Mount A12 module announced and previewed

Ricoh has announced a Leica M-mount unit for its modular GXR camera system. The GXR Mount A12 features a 12MP APS-C CMOS sensor with the ability to fit a wide range of M-mount lenses or a still wider choice if used in combination with an adapter. And, unlike the majority of digital cameras, it features no low-pass (anti-aliasing) filter. The Mount A12 module includes all the usual GXR features (such as toy camera and miniature processing modes), but also gains a silent electronic shutter mode, several manual focus assist options and a series of lens correction parameters. The module will be available from early September, at an MSRP of $649. We've been using a pre-production Mount A12 module for the past few days and have prepared an hands-on preview with real-world samples.

Ricoh announces GXR MOUNT A12

A GXR lens mount unit featuring an APS-C size CMOS sensor

Tokyo, Japan, August 5, 2011—Ricoh Co., Ltd. (president and CEO: Shiro Kondo) today announced the development and planned September 9, 2011 release of the new product GXR MOUNT A12, a lens mount unit exclusively for the GXR interchangeable unit camera system. The body color will be black only, and the planned monthly production volume is 3,000 units.

Introduced in December 2009, the GXR is a revolutionary interchangeable unit camera system in which lenses can be changed by mounting camera units that integrate lens, image sensor, and image processing engine into a single unit. In addition, utilizing its unique ability to accommodate interchangeable units other than camera units, the system can be expanded to include a variety of other devices.

The new GXR MOUNT A12 is a lens mount unit made especially for the GXR. Featuring an APS-C size CMOS sensor and a newly developed focal plane shutter, this unit makes it possible to mount lenses such as Leica M lenses, and it provides various types of compensation and correction functions.

Main features of GXR MOUNT A12

1) The newly adopted APS-C size CMOS sensor expands possibilities for high resolution and imaging power.

• The adoption of a CMOS sensor with an optimized micro lens layout makes it possible to secure sufficient brightness levels even in the peripheral areas of the image.
• The CMOS sensor used is 23.6mm × 15.7mm (APS-C size). It enables the shooting of high-quality images with smooth tone gradations as well as high definition and low noise.

2) Compatibility with a wide variety of lenses, including Leica M mount lenses.

• Compatible with the Leica M mount, GXR MOUNT A12 can, of course, handle M-mount lenses, and if a conversion adapter is used many more types of mounts can also be accommodated.
• A checking device is included for use in confirming whether or not your lenses are physically compatible.

3) Diverse new functions maximize the potential of the lens itself

• In order to accommodate the photographer’s own preferences by adjusting for the distinctive characteristics of many different lenses, GXR MOUNT A12 can independently correct coloring at the corners. Color shading correction is possible in a -4 to +4 range for both R and B.
• Peripheral illumination correction is possible in a -3 to +3 range.
• A distortion correction function is provided to correct for the distortion that tends to occur in the lens periphery. The photographer can select barrel and pincushion distortion and specify “strong,” “medium,” or “weak” for each.
• A glass optical filter was adopted and made as thin as possible. It increases periphery image quality and suppresses field curvature.

4) High-precision focusing

• A focus-assist function has been included in an effort to raise the accuracy of manual focusing. The photographer can select from two modes and check the focus by strengthening outlines and contrast.
• Magnifying the screen image while shooting is an effective technique for focusing. The magnification can be done not only in the center but throughout the image. In addition, the image quality for 4x and 8x magnification has been further enhanced. The area to be magnified can be moved using the directional pad.

5) Two shutter methods are featured: newly developed focal plane shutter and electronic shutter

• With the focal plane shutter, settings of 1/4000 sec. to 180 sec. are possible.
• With the electronic shutter, settings of 1/8000 sec. to 1 sec. are possible, and the photographer can shoot without worrying about shutter noise and vibration

6) The wide range of functionality that characterizes the GXR series

• My Settings enables a wide range of shooting functions to be specified in an instant. For the setting information storage, six patterns can now be stored in the body’s My Settings Box and six patterns can be stored in the SD card. This, along with the ability to change shooting conditions, further expands the photographer’s world of photo expression.
• In manual exposure mode, the shutter speeds B (bulb) and T (time) can be selected. With B, the exposure continues while the shutter release button is pressed, and with T, the shutter release button is pressed to start and end the exposure. For both B and T, the exposure is automatically ended when 180 seconds have elapsed.
• Information on the lens used can be put in the EXIF information. In the editing of My Settings information, lens name, focal length, and F value can be entered.
• New scene mode options have been added for the easy enjoyment of a wide range of photo expression. The five new options are soft focus, cross process, toy camera, miniaturize, and high contrast B&W. The photographer can create a unique image by just pressing the shutter release button.
• An electronic level utilizing an acceleration sensor.
• An image flag function to enable the quick display of specific images from among those in the camera. Up to 20 images can be flagged.
• 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 durability, light weight, and a superior feel in hand.
• It is possible to shoot 1280 × 720 pixel HD movies.

* Note: When shooting movies of 1280×720 size, the use of an SD/SDHC memory card with an SD speed class of Class 6 or higher is recommended.

7) New options added

• We have created the new soft cases SC-75B and SC-75T, which are easy to open and close. With SC-75B, it is possible to shoot with the case attached to the GXR body.
