Sony Alpha 550
The Sony Alpha a550 (DSLR-A550) is a midrange-level digital single-lens reflex camera (DSLR) marketed by Sony and aimed at enthusiasts, it was released in August 2009. The camera features a 14.2 megapixel APS-C Type CMOS Exmor Sensor and features Sony's patented SteadyShot INSIDE stabilisation system which works with any attached lens. The Sony Alpha a550's main selling point is its dual Live View mode's, Sony's normal secondary; smaller sensor based Live View mode and another which uses the main sensor with no autofocus. The a550 also features a maximum of 7frame/s continuous shooting speed when operating in speed-priority mode and a maximum ISO of 1600 when in auto mode and 12800 ISO when in manual mode. The Sony Alpha a550 is "big brother" to the Sony Alpha a500, an almost identical DSLR with a smaller 12.3 megapixel APS-C CMOS sensor, no 7frame/s continuous shooting and a lower resolution LCD. __TOC__ Live View The a550 stands out from other DSLR's in its price range wi ...

DSLR
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 ...

CMOS Sensor
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the image sensor is sometimes cal ...

Sony Alpha 500
The Sony α 500 (DSLR-A500) is a midrange-level digital single-lens reflex camera (DSLR) marketed by Sony, which was released in 2009. It features live view and body-integrated image stabilization. It has a 12.3 megapixel APS-C CMOS sensor. The camera itself received mostly good reviews, with its fast continuous shot function, much better image quality for photos taken in bad light situations compared to 3xx series and overall very good price/performance ratio. Inability to record videoclips, is the mostly often criticized point. Compared to A550, A500 features less detailed LiveView LCD, 12 contra 14 MPixel sensor resolution and absence of 7 frame/s continuous shot without autofocus mode. Both cameras also feature unique auto-HDR mode.

Live Preview
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF). Background The concept for cameras with live preview largely derives from electronic (video) TV cameras. Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SteadyShot
SteadyShot is the trademarked name of the integrated image stabilisation technologies used in Sony video camcorders, DSLR cameras, Mirrorless interchangeable-lens camera, mirrorless cameras and on Sony Xperia smartphones and Tablet computer, tablets. Different versions of these technologies are known as Super SteadyShot (SSS) in Sony's Cyber-shot product line, in addition to SteadyShot INSIDE (SSI) and Optical SteadyShot (OSS) in the Sony α family. Design When a camera is operated hand-held, the operator's shaky hands cause instabilities in the captured image stream. ''SteadyShot'' technology works inside the body of the camera. It uses motion sensors to detect the user's movements. SteadyShot then compensates for some of these movements, in some versions by moving the optics (OSS) and in some versions by moving the image sensor (also called IBIS: ''In Body Image Stabilisation'') in an opposite direction to the movement. This approach is contrasted to ''digital image stabilizatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Secure Digital HC
Secure Digital, officially abbreviated as SD, is a proprietary format, proprietary non-volatile memory, non-volatile Flash memory, flash memory card format developed by the SD Association, SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCard, MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1 ...
