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 ...

Sony Alpha 55
The Sony α55 (model variants SLT-A55V with GPS, SLT-A55 without GPS depending on country) is a midrange-level SLT camera, released in August 2010. Its design is novel due to its being the first digital single-lens translucent camera (SLT), along with the Sony α33. As an SLT it employs a semi-transparent mirror instead of an opaque mirror, which enables phase detection autofocus in live view. The design also replaces the optical viewfinder present in conventional DSLR with a high-resolution electronic viewfinder. The translucent mirror is fixed in position so does not have to flip up to take a still image, enabling rapid continuous shots of up to 10 frames per second. The static mirror also eliminates "mirror slap", the noise produced by the movement of the mirror during a shutter actuation, making the A55 quieter than standard DSLRs. The A55 is one of the first four Sony Alpha DSLR / SLT cameras with video mode included, capable of 1080i 1080i (also known as Full HD or ...

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] |
