Ricoh GR D Digital Compact

Masterpiece of ergonomic design and function.

The first Ricoh digital compact GR

The first Ricoh GR 8mp digital model launched in 2006 was based on the design of an earlier compact GR-1 fixed focal length lens film camera. The GRD's excellent 28mm (35mm format equivalent.) f/2.4 lens and miniature CCD sensor combination proved very capable, fitting neatly and ergonomically into a tough magnesium outer shell.

Orginal GR with accessory optical viewfinder and 21mm lens adapter and hood

Version two with a 10.1mp sensor was launched in 2007. Like its predecessor, The GR II camera is only 25mm thick (1 inch approx.). Its lightweight durable body casing is also manufactured from die-cast magnesium alloy able to withstand twists, pressure and shocks. Antimagnetic shielding also suppresses electromagnetism that can cause the generation of image noise. In every detail — reliability, high-class impression, portability, sturdiness and image quality — Ricoh has aimed at creating the ultimate in terms of well balanced body design.


Tough magnesium alloy body shell used for all three GRD models

The GRIII with a marginally increased body shell size of the same material, a new CCD sensor and new lens with a two stop increase in maximum aperture to f/1.9, replaced the GRII late in 2009. The lens cell configuration also changed from 6 elements in 5 groups on the GR II to 8 in 6 on the new model.

Special edition of the first Ricoh GR digital

The sensor in the GR III measures approx 7.6mm X 5.7mm ( 7.2mmX5.4mm for the GR II) with a pixel density of 23mp/cm2.  Electrical and chroma noise is well supressed by a new GR III engine at ISO sensitivities from 64 to 400. The 10mp effective spec of this device also allows reasonable scope for image cropping.


Third version of the GRD with new and faster lens in slightly larger body shell

By increasing the LCD screen size from 2.7 to 3 inches and upping its resolution to 920,000 dots, Ricoh's engineers needed a larger body shell to maintain ergonomic scaling of operating controls on the back panel. The 1.6 mm and 1.8mm increase in body length and height plus a hike of 20 grams in weight make a well balanced and easily manipulated tool.

Ricoh to Go! - Update
Front of the new Ricoh GR IV

Tokyo, Japan, September 15, 2011— Ricoh Co., Ltd. (President and CEO: Shiro Kondo) announced the development and release of the GR DIGITAL IV digital camera, the successor model to the GR DIGITAL III, which offers enhanced Quick Shooting capability and image quality. 

The GR DIGITAL III (released in August 2009) was a compact digital camera with high image quality that came with a 28mm/F1.9 GR Lens, the GR ENGINE III, and a high-sensitivity CCD that continued the evolution of the concepts originally introduced in the first GR DIGITAL model (released in October 2005). In the two years since its release, it has been enthusiastically received by a broad range of customers including professional and amateur photographers. 

GR IV - rear
The new GR DIGITAL IV, featuring a new image engine and a refined optical filter, exceeds the GR DIGITAL III and achieves the highest level of image quality in the history of the GR series.

Additionally, for the advancement of the Quick Shooting capabilities required to make sure you never miss a shot when out shooting, Ricoh has introduced a Hybrid AF System and an Image-sensor-shift Image Stabilization Function, which makes use of Ricoh's independently developed external AF sensor, and a 3-inch, approximately 1.23 million-dot VGA LCD monitor for heightened outdoor visibility. The addition of an electronic level that can detect inclination in the tilt direction, as well as the conventional horizontal direction also improves operability. Moreover, the inclusion of Dynamic Range Compensation makes it possible to shoot subjects in backlit or high-contrast scenes in the way the eye sees them, and Interval Composite, which can combine images shot at a certain shooting interval, advances the camera's expressive capabilities. 

White Limited Edition Ricoh GR IV - 10,000 units worldwide

GR IV White - top - but where is the Urushi Black lacquer edition? 

Ricoh will also continue to provide the highly praised function-expansion firmware.

Nikon 35Ti Quartz Date


1993 - Nikon 35Ti Quartz Date

In 1993, The Nikon corporation proudly presented their new Nikon 35Ti Quartz Date 35mm film camera (36 X 24mm format) - a high quality tool sporting an elegant yet rugged look and offering great picture taking performance with Matrix metering and a built-in 35mm Nikkor lens.

The 35Ti Quartz Date's solid titanium exterior is lightweight, strong and anti-corrosive. It houses the lens barrel and focusing helicoid, both made from durable, precision aluminium alloy for consistent and reliable focusing accuracy. The titanium casing also protects the motors and camera's state of the art microelectronic CPU and ICs.

The camera was unique at the time in having a clock styled analogue display showing shutter times (2sec - 1/500th sec + 10 mins long time exposure.), aperture setting, focus, frame counterSearch Amazon.com for nikon compact camera and exposure compensation on its top deck.

The active infrared autofocus system provided unmatched precision from 0.4 meters to infinity in 833 steps. Preset focus can also be set by rotating the command dial in conjunction with the AF button. Two types of exposure mode - program auto and aperture priority - both featured Nikon's exclusive 3D Matrix Metering with a new six segment Matrix sensor. Centre weighted metering was also available.

The lens fitted is the excellent six element four group 35mm /f.8 semi wide angle Nikkor that can be found in other high quality Nikon products such as the Nikon LWAF. In the 35TiSearch Amazon.com for compact camera camera, the optical cell configuration includes one high refractive index low dispersion element to ensure edge to edge frame sharpness while the Nikon lens multicoating reduces flare and image ghosting. The diaphragm has seven aperture blades, producing nicely rounded out-of-focus effects in front of and behind the focused plane. Image distortion and chromatic aberration are minimised by locating the shutter and diaphragm separately but in close proximity in the lens barrel.

Quartz date custom functions enhanced operation allowing the user to select date imprinting at the start of a film roll or on each frame. The camera also features a selectable Panorama mode (36mm X 13mm) and featured a built-in flash unit augmented with red-eye reduction features.

Nikon F - 1959

 1959: Nikon F. The beginning of everything
photo:copyright

by Jonathan Eastland

We know a great deal about the Nikon F. It was not only a brilliant technical innovation, the most robust feature of which has lasted to this day, it is also swathed in myth and mystery, the stuff of which legends are made. Long before anyone ever thought it would become a collectible item, an aura clung to this camera like autumn mist clings to the surface of a warm river. It has worked the front line of countless wars and conflicts, featured in a dozen movies and made some of the greatest photographs of all time in the hands of some of the greatest photographic reporters of the 20th century. Other marques come and go, get re-invented and sometimes, bring bigger and better innovations to the market. But the F lives on, its legendary status glued to the feel of a new D3x or a D300. 

During the early post war years of WWII, the remains of a once giant optical manufacturing association called Nippon Kogaku was reduced to a single plant with 1400 employees. In 1946, the company took the first steps which would later establish it as the foremost supplier of professional photographic equipment. Twenty examples of a prototype Nikon I, a 35mm rangefinder camera, were completed in September of that year. It was also the first occasion on which the word Nikon had been used; an amalgamation of NIppon KOgaku.

The camera was not a straight copy of the German Contax II on which the Nikon's body shell design is based. Nikon engineers reportedly researched and studied many types of German cameras of the period but settled on combining the best optical and mechanical aspects of the Leica and Contax while adding their own features.

Not surprisingly perhaps, considering Nikon's long history of specialised experience in optical glass making, it was the lenses for the rangefinder cameras which first captured the attention of western photographers. LIFE's David Douglas Duncan and photojournalist Horace Bristol used Nikkor lenses on their Leica and Contax Search Amazon.com for Nikon cameras to shoot Korean War assignments in the early 1950s.

Nearly 140,000 units of different rangefinder models had been made by the time the world moved on to the ubiquitous single lens reflex. Nikon kept the best design features of the rangefinder body shape and its slam-shut removeable back, the top plate layout and kinky shutter release position, adding a pentaprism, instant return mirror and the thin quilted titanium foil shutter blinds of its predecessor. When the Nikon F was launched in 1959, it was the first 35mm slr to have 100% eye level image coverage and a waist level finder and interchangeable focusing screens for different applications were easily fitted. Had its designers opted for the universal M42 screw threaded lens mount popular at the time, the Nikon F would have probably been an outstanding success when it was introduced, but they didn’t. Instead, the F got a patented, chunky stainless steel, quick change bayonet mount, the durability of which has been an unquestionable feature of all Nikon single lens reflex cameras to this day, maintaining compatibility for may older objectives with present day Nikon slrs and vice versa.

Voigtlander Heliar 15mm in Leica-M mount (VII)


Version II of the Voigtlander 15mm f/4.5 Heliar lens in Leica-M mount

The introduction of the Voigtlander Bessa L in the late 1990s simultaneously launched two wide angle lenses made for it. One of these was the diminutive Super Wide 15mm f/4.5 Heliar Aspherical. Designed with a 39mm Leica screw mounting thread, it could also be used on a plethora of older screw mount rangefinder cameras. With an adapter, it fits bodies with the Leica-M, Zeiss-ZM, Voigtlander-VM and the Epson RD1-M bayonet mount. It was the first truly super wide angle lens for modern rangefinder cameras with a 110 deg picture angle and maximum aperture greater than the f/8 of the 15mm Zeiss Hologon of 1972. It is so small and light, it can be carried in a pocket without encumbrance.

Cosina Co Ltd., of Japan launched a modified design of this lens early in 2009, offering improved user control while retaining the small and compact concept by applying its perceptions of older philosophies of form and function. Obtaining a sharp motif  with the original lens was rarely a problem because of its great depth of field latitude, even at maximum aperture. However, improved focus accuracy for close range objects is always useful so a rangefinder coupled distance measurement cam has been neatly engineered into a tight space and linked to a much improved focus ring with finger tab.

This new version of the Heliar has a fixed Leica-M bayonet mount and sports a touchy-feely raised red button on the lens barrel to facilitate mounting in the dark. Another excellent modification of the new design is a 10mm  front barrel diameter increase to allow the fitting of 52mm filters. The reshaping also enabled the designer to increase the diameter of the aperture setting ring just behind the petal shaped hood, giving it coarse serrated sides for improved thumb and finger control.

With a minimum aperture of f/22, the new Heliar uses the same eight element six group optical cell arrangement of its predecessor. A close inspection of the front and rear element groups of both objectives with a powerful halogen lamp reveals a subtle difference in the colour of coating reflections. The rear element of the new lens also appears, in side by side comparison, to be sited a millimeter or so further back than in the first model, a result perhaps of the engineering required for the inclusion of the rangefinder coupling cam. In practice, observable image improvements for the new glass seems slight; contrast is up a tad and the yellow content of whites is lower, marginally, than in renderings made with the old lens. The real benefits are in the much improved ergonomics and the ability finally, to mount a protective filter on this new Heliar.Search Amazon.com for Voigtlander Bessa cameras

It combines exceptional image quality with excellent maneuverability and outstanding reliability to simplify professional-level outdoor shooting. Thanks to the incorporation of a large, high-performance image sensor (measuring 44mm by 33mm) and PENTAX-original image-processing technology, it produces extra-sharp, super-high-resolution images with approximately 40 effective megapixels. It features remarkable durability and dependability, thanks to its lightweight but solidly built body featuring a magnesium-steel-alloy frame, reinforced glass LCD panel protectors and a reliable dustproof, weather-resistant construction. In addition, it is designed to be compatible with the majority of the existing PENTAX 645 system, so that current PENTAX 645-series camera users can take advantage of their valuable assets, including high-performance smc PENTAX 645 interchangeable lenses.


Major Features

1. Unprecedented image quality

    1.    Super-high-resolution images made possible by approximately 40 effective megapixels
The PENTAX 645D incorporates a high-performance CCD image sensor produced by Kodak. It measures 44mm by 33mm, and is approximately 1.7 times larger than its 35mm-format counterparts. Thanks to approximately 40 effective megapixels, it assures a wide dynamic range to faithfully reproduce the prevailing ambience and the sense of depth in super-high-resolution images that are rich in gradation and truthful in texture description. In order to bring out the full potential of the lens and the image sensor and assure the highest level of image-resolving power, the CCD unit is designed with no low-pass filters.

    2.    High-performance, high-speed PRIME II imaging engine
The PENTAX 645D features the acclaimed, PENTAX-original PRIME (PENTAX Real Image Engine) II as its imaging engine. Thanks to its high-speed data-processing capacity and new algorithm exclusively programmed for medium-format digital SLR cameras, this high-performance imaging engine produces super-high-quality images rich in gradation and faithful in color reproduction, while allowing speedy data transmission of large-volume image data — even RAW-format images as large as some 50MB per file.

    3.    14-bit A/D converter for faithful conversion of image data to digital signals
The PENTAX 645D features a high-performance A/D converter, which faithfully converts the large volume of analog image data output by the large CCD image sensor to digital signals carrying an extensive amount of image data, including resolution and gradation.
   
    2.    Solid, maneuverable body

 645D magnesium steel case and die-cast aluminium chassis

        The PENTAX 645D’s main frame is made of lightweight but strong magnesium-steel alloy, while the chassis is made of diecast aluminum to minimize the expansion and extension caused by heat and also to optimize kinematic accuracy and thermal stability. The LCD panels — one on the camera’s top panel, another on the back panel — are covered with tempered glass plates for extra protection. The PENTAX 645D’s body is also designed to be a compact and highly maneuverable medium-format camera, despite the incorporation of such dependable features as a dust-proof, weather-resistant construction with 70 special seals, outstanding cold-resistant performance to assure solid operation at a temperature as low as –10°C, and a newly designed shutter unit with a top shutter speed of 1/4000 second that can withstand as many as 50,000 shutter releases.
       
    3.    Dual SD/SDHC memory card slots

        The PENTAX 645D has a pair of memory card slots for the recording of images on both SD and SDHC memory cards. This dual-slot design gives the photographer extra data-storage options: for instance, recorded images can be assigned to different cards according to recording format (such as RAW or JPEG), or one of the cards can be used as the backup of the other. The settings for each memory card slot can be easily made by dedicated button.
       
    4.    Dependable DR II mechanism to minimize dust spots

645D 70 weather resistant seals

        The PENTAX 645D comes equipped with the highly dependable DR (Dust Removal) II mechanism, which effectively minimizes annoying dust spots on recorded images, even when the lenses are changed in dust-prone outdoor settings. By shifting UV/IR-cut filters placed in front of the CCD image sensor at supersonic speed using a piezoelectric element, this mechanism effectively and efficiently shakes dust off the image sensor. Thanks to the user-friendly dust-alert system, the photographer can check at a quick glance for dust adhering to the image sensor prior to the actual shooting.
       
   5.     Newly designed, high-precision 11-point wide-frame AF sensor

        The PENTAX 645D’s new SAFOX IX + wide-frame autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) to assure the extra-high-precision focusing demanded of medium-format digital SLR cameras. To develop this sophisticated AF system, the entire optical system was redesigned, at the same time with the addition of the new functionality to analyze and make use of the light sources data in the field of view.
   
     6.   Advanced 77-segment multi-pattern metering

        The PENTAX 645D employs a state-of-the-art, 77-segment multi-pattern metering system to assure super-high-accuracy light metering. The exposure accuracy is further enhanced by collecting such additional data as image orientation (horizontal or vertical) and the distance to and magnification of the subject using the sensors installed inside the camera body, with the obtained data incorporated into exposure calculations.
       
    7.    Large, easy-to-see optical viewfinder
 645D image viewing light path through glass prism

        Incorporated in the PENTAX 645D’s finder unit, a trapezoid-shaped glass prism not only assures an approximately 98% field of view, but also greatly contributes to the downsizing of the camera body. Coupled with a bright, easy-to-focus Natural-Bright-Matte focusing screen, the PENTAX 645D’s viewfinder offers a large, clear view of the subject.
       
    8.    Custom Image function to create desired visual effects with ease

        The PENTAX 645D’s Custom Image function lets the user easily control an image’s finishing touches to more precisely reflect the user’s creative intentions, or to more faithfully reproduce the ambience of the scene. The user can select one of eight modes, including the new Reversal Film mode designed to create images with the colors that are typical of reversal film. In addition, all parameters — such as saturation, hue, contrast, sharpness, key, and highlight/shadow contrast — can be easily adjusted to desired levels, so that the photographer can shoot images with great ease.
       
    9.    Versatile, multi-mode exposure system for faithful reproduction of creative intentions

    1.    Hyper Program function
The PENTAX 645D's Hyper Program function allows the user to instantly switch from Programmed AE mode to Shutter- or Aperture-Priority AE mode with a simple turn of the electric dials positioned around the grip. A single push of the green button shifts the exposure mode back to the original Programmed AE mode.
    2.    Hyper Manual function
When shooting in the Metered Manual mode, the PENTAX 645D's Hyper Manual mode lets the user to instantly set the proper exposure for the subject with a single push of the green button.
    3.    Sensitivity-Priority mode
The unique Sensitivity-Priority (Sv) mode automatically selects the optimum combination of aperture and shutter speed for the user-selected sensitivity. The sensitivity can be shifted swiftly by electronic dial on the back panel. The variable amount of the ISO could be configured to either 1/2 or 1/3 steps per click.
    4.    Shutter/Aperture-Priority mode
Taking full advantage of the unique capability of digital cameras for the automatic shifting of sensitivity at any time, the Shutter/Aperture-Priority (TAv) mode automatically selects the most appropriate sensitivity for the user-selected aperture/shutter-speed combination. It allows the user to effortlessly experiment with a greater range of photographic expressions.
       
    10.    Large, easy-to-view 3.0-inch LCD monitor with approximately 921,000 dots

        Positioned on the camera’s back panel, a large 3.0-inch color LCD monitor with approximately 921,000 dots provides a clear, bright view of onscreen images and menus. Since its wide-view design allows quick, effortless confirmation of the monitor image from approximately 170 degrees both horizontally and vertically, the photographer has little difficulty shooting images from low and high angles. The LCD monitor is also treated with exclusive AR (Anti-Reflection) coating to minimize reflections on the screen, even in the outdoor locations under bright sunshine.
