The Fujica X-mount was a lens mount created by Fujifilm in the late 1970s for the new Fujica SLR lineup : AX-1, AX3, AX-5, STX-1, STX-1N, STX-2. It replaced the old M42 screw mount used on their earlier SLRs. The mount is a bayonet type, with a 65° clockwise lock, and a flange focal distance of 43.5 mm.〔AX-1 owner's manual〕 With the advent of autofocus, the Fujica series of 35 mm SLR cameras was discontinued in 1985, rendering this mount obsolete.〔http://www.pentax-manuals.com/fujica/cameras/bay_bodies.htm〕 Fuji would return to the SLR market in 2000 with a series of digital SLR cameras starting with the FinePix S1 Pro, but these were based on Nikon designs and used the autofocus version of the Nikon F-mount. Fujifilm introduced a full line of twenty X-Fujinon lenses in this new mount (as well as some Fujinar lenses, not described here) : File:Fujifilm_X-Fujinon_lenses_line.png The "no-DM" lens cannot be used for program and shutter priority exposure modes of AX-3, AX5 SLR ; aperture priority and manual mode will work. An example of X-Fujinon lens, the 16mm fish-eye: There were some accessories that complied with Fujica X mount : - The "mount adapter X-S" for M42 lenses. - Two extension tubes : X25 (25mm) and X50 (50mm). - The "auto bellows X" used with a 50mm lens can provide 1 to 3x magnification. It can also be used with the "focusing rail X". The Fujica "slide copier X" mounted on the "focusing rail X" simplifies the copying of 135 film pictures. - The "macro cine copy X" is a macro lens with specific windows to take copies from 8mm and 16mm films. - The "microscope adapter X" to adapt the camera body to a microscope. - A "reverse adapter X", that can be mounted with an extension tube. - A classic "teleconverter 2X". ==See also== * Fujifilm X-mount 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「Fujica X-mount」の詳細全文を読む スポンサード リンク
