Shutter Lag
In photography, shutter lag is the delay between triggering the shutter and when the photograph is actually recorded, which includes all lag between when the shutter button is pressed and when the photo is taken, including metering and focus lag. it can be mitigated to an extent by pre-focusing and readying for action. Film cameras In film cameras, the delay is caused by the mechanism inside the camera that opens the shutter, exposing the film. Because the process is mechanical, however, and relatively brief, shutter lag in film cameras is often only noticeable (and of any concern) to professionals. SLRs have a slight additional lag due to the time it takes to move the mirror out of the way. Digital cameras Shutter lag is much more of a problem with digital cameras, although higher cost models tend to have less lag. The comet-tail artifact that early CCD sensors suffered from was significantly reduced by the invention of the pinned photodiode (PPD). It was invented by No ...

Photography
Photography is the visual arts, art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who operates a camera to capture or take Photograph, photographs is called a photographer, while the captured image, also known as a photograph, is the result produced by the camera. Typically, a lens is used to focus (optics), focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed Exposure (photography), exposure. With an electronic image sensor, this produces an Charge-coupled device, electrical charge at each pixel, which is Image processing, electro ...

Bandwidth (computing)
In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth. This definition of ''bandwidth'' is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, in which ''bandwidth'' is used to refer to the signal bandwidth measured in hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power. The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the noise on the channel. Network capacity The term ''bandwidth'' sometimes defines the net bit rate ''peak bit rate'', ''information rate'', or physical layer ''useful bit rate'', channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. For example, bandwi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sony NEX-5
The Sony α NEX-5 is a digital camera launched on 11 May 2010. It is a mirrorless interchangeable lens camera with the body size of a larger model fairly compact point-and-shoot camera with a larger sensor size (APS-C) comparable to that of some digital single-lens reflex cameras. Its major competitors in the market are the cameras based on the micro 4/3 standard created by Panasonic and Olympus, and a few low end Canon, Nikon, and even Sony α DSLRs. The NEX-5 shoots 14.2 megapixel stills and has a 7 frame/s continuous shotmode. It has the capability to shoot 1920×1080i at 60 frame/s in AVCHD or 1440×1080p at 30 frame/s in MPEG4. The NEX-5 was replaced by the 16 megapixel NEX-5N in August 2011. Features The α NEX-5 has features found in SLR cameras but also some that are normally found in point and shoots. The body of the α NEX-5 is made of magnesium alloy that separates the NEX-5 from the less expensive polymer NEX-3. Also different from the NEX-3 is video quality. T ...

Konica Minolta Maxxum 7D
The Maxxum 7D, labelled Dynax 7D in Europe/Hong Kong and α-7 Digital in Japan and officially named "DG-7D", is a 6.1 megapixel digital single-lens reflex camera, or DSLR, produced by Konica Minolta. It was the top model of their DSLR range; the Maxxum/Dynax 5D consumer-grade model was the other. The 7D was first announced on 2004-02-12 at the PMA show, with full details released just before the 2004 photokina show on 2004-09-15. The production camera was released in late 2004. Production ceased when Konica Minolta announced their exit from the camera business in January 2006. Regardless of its high specification (for the time) and innovative feature set, it came with a very high price tag. The 7D was available as body only, but also with a 17-35mm 2.8-4 kit lens. Like the Nikon 18-70 kit lens found with many Nikon DSLRs, this lens was regarded as of high enough quality to do justice to the sensor within the body, unlike the cheap zoom kit lenses found with many DSLRs.

Canon PowerShot A
The Canon Canon PowerShot, PowerShot A is a discontinued series of digital cameras released by Canon Inc., Canon. The A-series started as a budget line of cameras, although over time its feature set varied from low-end point-and-shoot cameras to high-end wikt:prosumer#Etymology 2, prosumer cameras capable of rivalling Canon's Canon PowerShot G, PowerShot G-series. Models The series began with the A5, which was a very basic point-and-shoot camera line. The Axx series that followed offered full manual control (on most models) in a fairly bulky body. The A100/200/3xx/4xx series cameras are stripped-down with very little manual controls. The Axx series later branched off into the A5xx (replaced by the A1xxx series), A6xx, and A7xx series (the latter replaced by the A2xxx series). A-series cameras are generally powered by 2 AA batteries.

Lumix
Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs. Compact digital cameras DMC-LC5 and DMC-F7 were the first products of the Lumix series, released in 2001. Most Lumix cameras use differing releases of the Panasonic Venus Engine for digital image processing; the original version (2002) was followed by II (2004), Plus (2005), III (2006), IV (2008), HD, V (2009) and VI, HD II, FHD (2010). Some Lumix models are branded with Leica lenses (e.g. Nocticron or Elmarit lenses), although Leica does not manufacture the lenses. Others are rebranded as Leica cameras with different cosmetic stylings. Despite shifting focus to full frame cameras, Panasonic continues to release and support micro four thirds (MFT) cameras. As of 2023, the Lumix G9II is the flagship MFT camera of the range. Model lines Some cameras are available in a choice of color, indicated by a suffix letter: K is black, S silver, A blue, R red, W white. Mos ...

Mirrorless Camera
A mirrorless camera (sometimes referred to as a mirrorless interchangeable-lens camera (MILC) or digital single-lens mirrorless (DSLM)) is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) and compact system camera (CSC). When compared to similar DSLRs, these cameras can be smaller, lighter, and quieter. In cameras with mirrors, light from the lens is directed to either the image sensor or the viewfinder. This is done using a mechanical movable mirror which sits behind the lens. By contrast, in a mirrorless camera, the lens always shines light onto the image sensor, and what the camera sees is displayed on a screen for the photographer. Some mirrorless cameras also s ...
