Ricoh intends on 4 December 2009 with a new removable Module GXR-camera system on the market. This lens and image sensor forming an encapsulated host module, which in a camera module, the GXR stuck. The camera serves as a user interface with battery, memory card, screen, flash shoe, flip-flash, image processor show host interfaces, etc. The first two modules, what is possible. One combines an APS-C sensor with a large-aperture macro lens, the other a compact sensor with a 3x optical zoom.

As new as Ricoh claims that the idea is not, however. As early as 1999 there were from the Minolta Dimage EX, for which there was a wide-angle and a telephoto module. The Ricoh system, but plays off the benefits of current technology and combined depending on the application of different focal length lenses and image sensors of different sizes together. The system is smaller and lighter than Micro Four Thirds. The camera module itself measures 114 x 70 x 29 mm and comes with a sturdy magnesium housing, about 200 grams on the scales. It will cost around 460 euros, which we have but still no recordable device. What is needed is still one of the recording modules. The name GXR is composed of the extensible digital camera Ricoh GX and the earlier analog Change objectively cameras XR together.
The design of the camera module is very technical and functional. Power is supplied by the Li-Ion Battery DB-90, which ranges depending on the host module 320 (with GR-50 mm Macro lens) or 410 (with Ricoh lens 24-72 mm) photographs. The images are stored as JPEG or RAW (in the DNG format) to SD or SDHC memory cards increases, but also the GXR videos (in AVI Motion JPEG). The rear screen dissolves his 920,000 dot (VGA 640 x 480 pixels) and measures 3 “(7.6 cm) diagonally. With a high viewing angle, covering the whole of the sRGB color space, an anti-reflection and anti - scratch coating, it offers plenty of comfort.
The built-in flash can be folded and offers in addition to Auto, Red-eye pre-flash, Slow Sync and Flash Compensation Fill function a manual as well as twelve levels up to 1 / 64. Via the hot shoe is not only external flash units, but also the new electronic viewfinder VF-2 can be connected. It is hinged at 90 ° upwards and also provides 920,000 dot resolution. Interval shooting dominates the GXR, as well as exposure bracketing and white balance bracketing, a self-timer, selectable grid lines, histogram, digital spirit level and a depth of field display, the camera module. Its interfaces include USB in addition, power supply connector (the matching AC adapter AC-5 will not exist in Europe) and AV-out and a mini-HDMI jack and a Far from solver connection.
The recording modules offer over conventional change objectively systems a perfect protection against dust. They are connected via a simple sliding mechanism. This is built tough and provides protection against tilted preparation. The electronic connection is via a 68pin interface. Here are conceivable for the future in addition to other camera modules, such as a projector module, a memory module, a printer module, etc. The interface itself is not a open system, but Ricoh is very willing to work with equipment vendors together.
One of the first two modules, the Ricoh camera lens 2,5-4,4 / 24-72 mm VC (S10), it will cost 370 EUR. Although it is very compact, which corresponds to a 1 / 1, 7 “small CCD sensor and 10-megapixel resolution, however, more customary compact camera. The triple zoom wide appeal to fans especially. As promised, on behalf of the VC, it has a mechanical image stabilization, The movably mounted on the image sensor (CCD-shift is implemented). The sensitivity ranges from ISO 100 to 3,200. In addition to photos, the module also controls VGA movies at 30 fps recording. Continuous shooting the “S10″ as well, at full resolution to 1.6 frames / s, which is closing after just five shots.
The image quality, Ricoh will have good balance between speed photography and the conditions for ambitious post-processing, ie, although the photos are crisp, but be processed not excessive. Similar to the GR can be connected are available with the sunshield must optical accessories for a Adaptertubus. This is a 0.79 times wide-angle converter, which will reach 19 mm focal length (KB) of 1.88 times teleconverter however, brings it to 135 mm (KB). Smart is the automatic lens cover is also optional, the three blades are held shut by springs. You will be impressed when you switch from the emergent lens.
The second offered to launch camera module “GR Lens 1:2,5 / 50 mm Macro (A12)” indicates that F2, 5-bright 33mm fixed focal length. The CMOS image sensor was at 23.6 x 15.7 mm APS-C size, so the lens is a classic 50 mm equivalent. With a minimum focusing distance of 7 cm from the front lens reaches a maximum magnification ratio of 1:2 and shall logically “Macro call”. Over a image stabilizer, the module has not, however. Nine lenses (including one aspherical on both sides) into eight groups and the Floating Focusing system will ensure the highest image quality.
The module is not quite as compact as the 24-72, even the accessories can not join them, but the GR-lens has a manual focus ring, the electronic “fly-by-wire is translated”. Video cameras to achieve with this module even 1,280 x 720 pixels to support HD resolution, but only at 24 frames / s. This suggests that there is an image sensor of the Sony range, as well as in the Nikon D90, D5000 and D300s is used. Light sensitivity ranges from ISO 200 to 3,200, a series of images are at maximum resolution at 3 frames / s made, but after inserting 4 pictures, the camera needs a breather. Around EUR 670 Ricoh would like to have for this module. It should be suitable in addition to macro shots especially for portraits, Ricoh emphasizes the creamy bokeh.
The system is thus very high priced products and compete with middle-located DSLR and Micro Four Thirds, depending on the camera module is the compactness bought with camera but picture quality. For 2010, Ricoh is a high-speed telecommunications module in prospect. It will be expected to increase by a 1 / 2, 3 “small high-speed CMOS sensor with 9.3 Megapixel resolution in combination with a 28-300mm super zoom. In addition, Ricoh announced the functions of the camera module and the Lens Modules with firmware updates to expand regularly.
