Olympus Pen
The Pen, or PEN series is a brand of Olympus. It was used on analog half-frame compact and SLR models from 1959 until the early 1980s. In 2009, Olympus released the PEN E-P1, a digital mirrorless interchangeable-lens camera, which opened the range of Digital PEN models, which are still sold today. Olympus Corporation's camera division since has been bought by Japan Industrial Partners, and run under the OM Digital Solutions name. They continue to run the Digital PEN series. General context The original Pen was introduced in 1959. It was designed by Yoshihisa Maitani, and was the first half-frame camera produced in Japan. It was one of the smallest cameras to use 35mm film in regular 135 cassettes. A series of derivatives followed, some easier to use with the introduction of exposure automation, e.g. the Pen EE; others with a wider aperture lens and a manual meter, such as the Pen D. In 1966 the arrival of the Rollei 35, a camera almost as compact but making normal 24×36 exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Viewfinder
An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED) which the photographer can look through when composing their shot. It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power. The sensor records the view through the lens, the view is processed, and finally projected on a miniature display which is viewable through the eyepiece. Digital viewfinders are used in digital still cameras and in video cameras. Some cameras (such as Panasonic, Sony, Fujifilm) have an automatic eye sensor which switches the display from screen to EVF when the viewfinder is near the eye. More modest cameras use a button to switch the display. Some have no button at all. While many cameras come with a built-in EVF, this is fixed in place and can only be used while holding the camera to the user's eye, which may not be convenient. Other cameras don't come ...

Hot Shoe
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D">Sony.html" ;"title="Minolta and older Sony">Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash (photography), flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization. The hot shoe is a development of the standardised "accessory shoe", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a cable. The dimensions of the hot shoe are defined by the International Organization for Standardization in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design The ...

Olympus PEN E-P2
The Olympus Pen E-P2 announced on 5 November 2009 is Olympus Corporation's second camera that adheres to the Micro Four Thirds (MFT) system design standard. The E-P2 succeeds the Olympus Pen E-P1 a little over five months after the introduction of the EP-1. Features The EP-2 addresses some of the concerns that critics had about the EP-1: slow autofocus speed and difficulty seeing the LCD panel under certain (e.g., bright, sunny) conditions. The autofocus speed was addressed with a firmware update, and the introduction of new lenses, although critically, the autofocus speed does not improve much with the originally issued 14–42 mm ƒ/3.5–5.6 kit zoom lens (28–90 mm equivalent), or the 17 mm ƒ/2.8 (34 mm equivalent) pancake lens. The EP-2 added an Accessory Port, a power and communication port, which allowed the use of various accessories, such as an external stereo microphone for HD video recording. However, the principal use of the accessory port w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-body 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 ...

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 2010 ...

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 Four Thir ...

Olympus PEN E-P1
The Olympus Pen E-P1 announced on 16 June 2009 is Olympus Corporation's first camera that adheres to the Micro Four Thirds (MFT) system design standard. The first camera to use the Micro Four Thirds mount was Panasonic's G-1 camera. Features The design of the camera is reminiscent of the Olympus Pen half frame film cameras and is marketed as the Olympus digital PEN. The model presented on 16 June 2009 was very similar in looks to the Olympus Pen F. Initially, two micro 4/3 lenses were available from Olympus, one 14–42 mm f/3.5–5.6 zoom and a 17 mm f/2.8 pancake prime lens. Remarkably, with the exception of the optical viewfinder, the E-P1 seemed to fit most of the features found on the Olympus E-620, a larger Four Thirds system DSLR, into the small, compact MFT form factor. In addition to Micro Four Thirds lenses, Olympus offers adapters allowing the use of Four Thirds lenses, or OM Zuiko lenses originally manufactured for use on the classic OM series of film ...

Autofocus
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers. Autofocus accu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Sensor
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging. The two main types of electronic image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor). Both CCD and CMOS sensors are based on metal–oxide–semiconductor (MOS) technology, with CCDs based on MOS capacitors and CMOS senso ...
