The EOS-1N is a 35mm single lens reflex (SLR) camera body produced by Canon. It was announced by Canon in 1994, and was the professional model in the range, superseding the original EOS-1.〔(Canon Camera Museum, EOS-1N )〕 The camera was itself superseded by the EOS-1v in 2000. The original EOS-1 had been launched in 1989, two years after the company had introduced their new EOS autofocus system. It was the company's first professional-level EOS camera and was aimed at the same photographers who had used Canon's highly respected, manual focus professional FD mount SLRs, such as the Canon New F-1 and the Canon T90.〔(Canon EOS-1N Series AF SLR camera )〕 On a physical level the EOS-1 resembled the T90, which had been designed for Canon by Luigi Colani. The EOS-1N was a revision of the EOS-1, with five autofocus points spread across the frame rather than a single centrally-mounted autofocus point, plus more effective weather sealing, a wider exposure range, and numerous other improvements.〔(Photonotes ): EOS 1, EOS 1N, 3 and 1V〕 In common with the EOS-1, the 1N used Canon's A-TTL automatic flash system, and does not support the more modern E-TTL. ==Features== At the time of its creation, The Canon EOS-1N was placed at the top of Canon's EOS camera line. The camera featured polycarbonate external construction with weather-resistant seals around buttons, dials and its Canon EF lens mount. The fixed eye-level pentaprism viewfinder has 100-percent vertical and horizontal coverage, has dioptric viewfinder adjustment from –3 to +1 diopter and has as a viewfinder eyepiece blind to block stray light when on a tripod. For automatic focusing, the camera used a 5-point BASIS auto focus system with the sensors arranged horizontally across the middle of the viewing area. The center point is a cross-type, which detects horizontal and vertical lines, while the outer four detect vertical lines only. Metering modes include a 16-zone evaluative, center-weighted average, partial, selectable spot, and fine central spot metering mode. Film speeds can be set from ISO 6-6400 either manually or automatically by DX codes on the film canisters. The camera allows variable Program autoexposure, as well as aperture-priority and shutter-priority automatic exposure and manual exposure. Another option is Depth-of-field AE (DEP), an automatic mode that selects the focusing distance and aperture f-number to place the depth of field between two user-specified near and far points. Shutter speeds range from 30 seconds to 1/8000 of a second in all exposure modes. A non-timed bulb speed is available. Flash X-sync is available up to a shutter speed of 1/250 of a second. There are 14 custom functions to change the way the camera operates, which set options like exposure steps and mirror lock-up. The camera has user-interchangeable focusing screens, interchangeable with those out of other EOS-1-series cameras, and a now-discontinued interchangeable Canon Command Back E1. Power comes from one 2CR5 battery, an optional BP-E1 Battery Pack housing four AA alkaline or lithium batteries or the PB-E1 Power Booster drive housing eight AA batteries and allowing for 6 frames per second to be photographed, depending on the type of battery and the shutter speed selected. The camera weighs in at 855 grams, or 1 lb and 14.15 oz. 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「Canon EOS-1N」の詳細全文を読む スポンサード リンク
