Mavica (''Magnetic Video Camera'') was a brand of Sony cameras which used removable disks as the main recording media. In August 1981, Sony announced the Sony Mavica electronic still camera, the first electronic still camera. It was not a digital camera, as its CCD sensor produced an analog video signal in the NTSC format at a resolution of pixels. Mavipak 2.0" disks (later adopted industry-wide as the Video Floppy and labelled "VF") were used to write 50 still frames onto tracks on disk. The pictures were viewed on a television screen. Otherwise, this camera is positioned as the "pioneer of the digital era".〔(【引用サイトリンク】url=http://www.digicammuseum.com/en/history )〕 The unreleased original MAVICA as well as the later ProMavica MVC-5000 and MVC-7000 were designed as single-lens reflex systems with interchangeable lenses.〔"The Mavica was a single lens reflex with interchangeable lenses. The original Mavica was provided with three bayonet-mounted lenses: a 25mm f/2, a 50mm f/1.4, and 16-65mm f/1.4 zoom." (Mavica introduction in 1981 )〕〔(Brooke Clarke's PSC-6 web site showing a ProMavica MVC-5000 and mentioning an assortment of compatible lenses: 400mm, 60-300mm zoom, night vision lens, "Wide Lens 5mm 1:1.8 Sony" (MCL-05H), "Zoom Lens 9.5 - 123.5mm 1:1.8 Made by Canon" (MCL-913T) )〕 At least the ProMavica MVC-7000 also featured lens mount adapters for Nikon and Canon lenses.〔Sony Product Flyer of ProMavica MVC-7000 listing camera features and mentions accessories including Sony-bayonet-mount lenses: "wide lens" (MCL-06T), "zoom lens" (MCL-903T), "zoom lens" (MCL-806H), "wide lens" (MCL-05H) and "zoom lens" (MCL-710H) as well as two lens adapters for Nikon (MCL-200N) and Canon (MCL-300C)〕〔(Forum thread showing a photo of the ProMavica MVL-7000 SLR with MCL-200N lens adapter )〕 The VF format soon evolved into the backward-compatible Hi-VF format, supported by the ProMavica MVC-7000 and the Hi-Band Mavica models. == Features == The later Digital Mavicas recorded onto 3.5" 1.4 MiB 2HD floppy disks in computer-readable DOS FAT12 format, a feature that made them very popular in the North American market. With the evolution of consumer digital camera resolution (megapixels), the advent of the USB interface and the rise of high-capacity storage media, Mavicas started to offer other alternatives for recording images: the floppy-disk (FD) Mavicas began to be Memory Stick compatible (initially through a Memory Stick Floppy Disk adapter, but ultimately through a dedicated Memory Stick slot), and a new CD Mavica series—which used 8 cm CD-R/CD-RW media—was released in 2000. The first CD-based Mavica (MVC-CD1000), notable also for its 10× optical zoom, could only write to CD-R discs, but it was able to use its USB interface to read images from CDs not finalized (CDs with incomplete sessions). Subsequent models are more compact, with a reduced optical zoom, and are able to write to CD-RW discs. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Sony Mavica」の詳細全文を読む スポンサード リンク
