Olympus E-3
The Olympus E-3 was until 2010 Olympus Corporation's flagship camera, positioned as a professional DSLR camera. It is the successor to the Olympus E-1, which was launched in November 2003. The E-3, originally codenamed Olympus E-P1, was announced on 17 October 2007. The E-3, like the other cameras in the Olympus E-series, conforms to the Four Thirds system. It was succeeded in 2010 by the Olympus E-5 professional DSLR flagship camera. Features The E-3 has several novel features, including a live preview full articulating screen, autofocus in live view mode, the ability to capture a scene with wide dynamic range using an image processing method called ''shadow adjustment technology'' and the ability to control up to three wireless flash groups without external transmitters. The camera is also fully weatherproof even with the popup flash in the "up" position. The camera, with the new SWD ( ultrasonic motor) lenses, is expected to appeal to professional users who want a rugged, ...

Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame format, t ...

Four Thirds System
The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development. The system provides a standard that, with digital cameras and lenses available from multiple manufacturers, allows for the interchange of lenses and bodies from different manufacturers. seems to cover the standard. Proponents describe it as an open standard, but companies may use it only under a non-disclosure agreement. Unlike older single-lens reflex (SLR) systems, Four Thirds was designed from the start to be entirely digital. Many lenses are extensively computerised, to the point that Olympus offers firmware updates for many of them. Lens design has been tailored to the requirements of digital sensors, most notably through telecentric designs. The size of the sensor is significantly smaller than for most DSLRs and this implies that lenses, especially telephoto lenses, can be smaller. For example, a Fou ...

Vignetting
In photography and optics, vignetting is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word ''vignette'', from the same root as ''vine'', originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait that is clear at the center and fades off toward the edges. A similar effect is visible in photographs of projected images or videos off a projection screen, resulting in a so-called "hotspot" effect. Vignetting is often an unintended and undesired effect caused by camera settings or lens limitations. However, it is sometimes deliberately introduced for creative effect, such as to draw attention to the center of the frame. A photographer may deliberately choose a lens that is known to produce vignetting to obtain the effect, or it may be introduced with the use of special filters or post-processing procedures. When using superzoom lenses, vignetting may occur all alo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dust Reduction System
A dust reduction system, or dust removal system, is used in several makes of digital cameras to remove dust from the image sensor. Every time lenses are changed, dust may enter the camera body and settle on the image sensor. Digital single-lens reflex cameras (DSLR) are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other forms of digital cameras, and the image sensor is fixed, unlike a film camera. Even the tiniest (micrometre-size) dust particles or other contaminants that settle on the face of the image sensor (individual pixels of which have dimensions on the order of ~5 micrometres) may cast shadows and thus become visible in the final image as more or less diffuse grey blobs, depending on aperture. Dust may be generated by internal moving parts or may be moved by air currents within the camera. Some systems remove or clean the sensor by vibrating at a very high frequency—between 100 hertz and 50 kilohertz. T ...

Image Stabilization
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is mainly used in high-end image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto or zoom). With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens shake is added to variation in the atmosphere, which changes the apparent positions of objects over time. Application in still photography In photography, image stabilization can facilitate shutter speeds 2 to 5.5 stops slower (exposures 4 to times l ...

Ultrasonic Motor
An ultrasonic motor is a type of piezoelectric motor powered by the ultrasonic vibration of a component, the stator, placed against another component, the rotor or slider depending on the scheme of operation (rotation or linear translation). Ultrasonic motors differ from other piezoelectric motors in several ways, though both typically use some form of piezoelectric material, most often lead zirconate titanate and occasionally lithium niobate or other single-crystal materials. The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors. Ultrasonic motors also offer arbitrarily large rotation or sliding distances, while piezoelectric actuators are limited by the static strain that may be induced in the piezoelectric element. One common application of ultrasonic motors is in camera lenses where they are used to move lens elements as part of the auto-focus system. Ultrasonic motors replace the noisier and ofte ...

Articulating Screen
An articulating screen is a built-in small electronic visual display which is not fixed, but rather can be repositioned using a hinge or pivot. The articulating screen is known under different other names such as flip-out screen, flip screen, adjustable screen, articulated screen, or hinged screen. According to the way it moves, there are four main types: #The display moves around one axis, so that it only tilts. It is called ''tilting screen'' or ''tiltable screen''. #The display tilts horizontally both up and down and also vertically. This type is called ''double-hinged tilting screen'', ''two-axis tilting screen'', ''three-direction tilting screen'' or ''screen with 3-way tilt''. #The display moves around two axes which are at a right angle to each other, so that the screen both tilts and swivels. This type is called ''swivel screen''. Other names for this type are ''vari-angle screen'', ''fully articulated screen'', ''fully articulating screen'', ''rotating screen'', ''multi-an ...

Olympus E-1
The Olympus E-1, introduced in 2003, was the first DSLR system camera designed from the ground up for digital photography This contrasts with its contemporaries which offered systems based on reused parts from previous 135 film systems, modified to fit with a sensor size of APS-C. Features The E-1 uses the Four Thirds System lens mount and imaging system. This design choice means that because the CCD is smaller than a 35 mm negative, Four Thirds System lenses and camera bodies can be made smaller and lighter than those of preceding SLRs. Characteristics: *Lighter/more compact than contemporary DSLR bodies *5 megapixel CCD *Good dynamic range and exposure *Magnesium-alloy body *Environmental sealing (splash proof) *"Supersonic Wave Filter" dust reduction system cleans CCD at each camera start-up (dust is shaken off the CCD) *USB 2.0 and FireWire connectivity *Continuous shooting 3 frames per second up to 12 frames *Hybrid white balance sensor (on external surface of camera ...

Digital Single-lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...
