Sony α99 II
The Sony α99 II is a flagship Sony SLT camera and continues the line of Sony A-mount camera bodies. It was first announced by Sony on September 19, 2016 at photokina 2016 and replaced the original Sony α99. Its single-lens translucent design allows for faster focusing and shooting than DSLRs. Consequently, at 12 FPS, it can shoot roughly twice as fast in continuous burst mode as competing models as of 2016. The α99 II also features best-in-class low-light autofocus. Initial demand for the camera exceeded the supply in Japan and major American retailers also quickly sold out of allocated amounts and had backordered supplies as of December 2016. The a99 II was the last a-mount camera. After five years from its launch, Sony decided to discontinue all a-mount cameras including the a99 II, in 2021. That was the end of the a-mount cameras lineup that lasted 36 years from 1985 during the Minolta SLR film era until 2021 with Sony digital SLT technology. See also *Exmor R Exm ...

Sony SLT Camera
Single-lens translucent (SLT) is a Sony proprietary designation for Sony Alpha cameras which employ a pellicle mirror, electronic viewfinder, and phase-detection autofocus system. They employ the same Minolta A-mount as Sony Alpha DSLR cameras. Sony SLT cameras have a semi-transparent fixed mirror which diverts a portion of incoming light to a phase-detection autofocus sensor, while the remaining light strikes a digital image sensor. The image sensor feeds the electronic viewfinder, and also records still images and video on command. The utility of the SLT design is to allow full-time phase-detection autofocus during electronic viewfinder, live view, and video recording operation. With the advent of digital image sensors with integrated phase-detection, the SLT design is no longer required to accomplish this goal, as evidenced by cameras such as the Sony NEX-5R, Fujifilm X-100s, and Nikon 1, although the SLT design avoids having pixels unavailable for image formation due to their s ...

Cameras Introduced In 2016
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 accuracy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exmor R
Exmor is the name of a technology Sony implemented on some of their CMOS image sensors. It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor. Exmor RS is the world's first stacked CMOS image sensor and was announced by Sony on 20 August 2012. Subsequently, Sony announced the first 3-layer stacked CMOS sensor, which added a DRAM cell array in the middle.

Frame Rate
Frame rate (expressed in or FPS) is the frequency (rate) at which consecutive images (frames) are captured or displayed. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the , and be expressed in hertz. Frame rate in electronic camera specifications may refer to the maximal possible rate, where, in practice, other settings (such as exposure time) may reduce the frequency to a lower number. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals. The human visual system can process 10 to 12 images per second and perceive them individually, while higher rates are perceived as motion. Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz. This perception of modulated light as steady is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sony α99
The Sony Alpha 99 was announced by Sony on September 12, 2012. It was the flagship Sony DSLR camera and of the Sony Alpha SLT line until late 2016 when it was replaced by the Sony α99 II. It features the 24.3MP 35mm full-frame Exmor APS HD CMOS sensor, with the normal sensor range of ISO 100–3200. The selectable sensitivity is up to ISO 25600, which makes this camera able to capture still images in low-light environments. This camera can also combine six images together, to generate a single image with two additional steps of ISO sensitivity. This is also the first Sony Alpha camera to use the new Sony "Mult-Interface" shoe which is a standard ISO shoe with proprietary contacts at the front of the shoe. This allows use of standard ISO hotshoe accessories without the need for adapters as in previous Alpha models. The camera ships with an adapter to allow use of older Minolta-style hot-shoe accessories. Like Sony's APS-c flagship, α77, the α99 has the ability to record F ...
