Sony α5100
The Sony α5100 (model ILCE-5100) is a digital mirrorless camera announced by Sony on 18 August 2014. Reception The camera has been well received because of its performance and its features. Drawbacks and missing features One of the main drawbacks is the fake shutter sound that the camera emits when taking a photo, something that many reviewers noted that worsens the experience of taking photos, as the sound cannot be turned off. This fake shutter sound can be clearly heard when shooting at 1/10 s or slower, at faster speeds it is either not emitted or the sound appears to blend in with the mechanical rear curtain shutter sound. This fake shutter sound is probably present in order to indicate to the camera user that the exposure has started, most likely to mimic a mechanical front curtain, as most Sony cameras now have electronic front curtains. Missing from this camera model is a dedicated physical ''Fn'' button, standard for most Sony mirrorless cameras. Also the programmable ...

CMOS
Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", , ) is a type of MOSFET, metal–oxide–semiconductor field-effect transistor (MOSFET) semiconductor device fabrication, fabrication process that uses complementary and symmetrical pairs of p-type semiconductor, p-type and n-type semiconductor, n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including Nonvolatile BIOS memory, CMOS BIOS), and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data conversion, data converters, RF circuits (RF CMOS), and highly integrated transceivers for many types of communication. In 1948, Bardeen and Brattain patented an insulated-gate transistor (IGFET) with an inversion layer. Bardeen's concept forms the basis of CMOS technology today. The CMOS process was presented by Fairchild Semico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling Shutter
Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of the image of the scene are recorded at the same instant – however, during playback, the entire image of the scene is displayed at once, as if it represents a single instant in time. This produces predictable distortions of fast-moving objects or rapid flashes of light, referred to as rolling shutter effect. This process in contrast with global shutter in which the entire frame is captured at the same instant. The rolling shutter can be either mechanical or electronic. The advantage of this electronic rolling shutter is that the image sensor can continue to gather photons during the acquisition process, thus effectively increasing sensit ...

Sony E-mount
The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience") and Sony ILCE camera, ILCE series of camcorders and mirrorless interchangeable lens camera, mirrorless cameras. The E-mount supplements Sony's Sony α, α mount, allowing the company to develop more compact imaging devices while maintaining vignetting with 35mm sensors. E-mount achieves this by: * Minimising mechanical complexity, removing mechanical aperture and Focus (optics), focus drive. * Shortening the flange focal distance to 18 mm compared with earlier offerings from Sony which used 44.5 mm. * Reducing the radius of the flange. * Relying on software to correct vignetting The short flange focal distance prohibits the use of an optical viewfinder, as a mirror box mechanism cannot be included in this reduced distance. Therefore, all E-mount cameras use an electronic viewfinder. History Initially, E-mount was implemented on the Sony α Sony NEX-3, NEX-3 and Sony NEX-5, NEX-5 consume ...

Mirrorless Interchangeable-lens 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 ...

List Of Smallest Mirrorless Cameras
This is a list of the lightest and smallest mirrorless digital cameras ever released with an interchangeable lens mount, excluding smartphones and action cameras, sorted by weight including battery and memory card. Nearly all the lightest models have been discontinued, as smartphone cameras have rapidly improved and taken over their market. Some high-end smartphones now exceed several of these models in weight, sensor size, and functionality. (For example, an iPhone 15 Pro Max weighs 221 g, and a Galaxy S24 Ultra weighs 233 g.) The lightest mirrorless cameras in production today are the Olympus E-P7 at 337 g and Sony ZV-E10 at 343 g. The lightest models in production with an electronic viewfinder (EVF) are the Panasonic G100D at 346 g and Canon R100 at 356 g. With the exception of the E-P7's in-body image stabilization (IBIS), these models eschew certain hardware features, such as IBIS and weather sealing, that add weigh ...

Live-preview Digital Cameras
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] |
