The Fujica X-mount was a lens mount created by Fujifilm in the late 1970s and early 1980s for the new Fujica SLR lineup: AX-1, AX-3, AX-5, AX Multi, STX-1, STX-1N, STX-2, MPF105X, MPF105XN. It replaced the 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.^[1]

With the advent of autofocus, the Fujica series of 35 mm SLR cameras was discontinued in 1985, rendering this mount obsolete.^[2] 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 line of twenty-seven X-Fujinon lenses with this mount (as well as three Fujinar lenses):

The following lists Fujifilm X-Fujinon lenses with this mount (not including Fujinar lenses with this mount).

Not on that list are the following lenses:

• EBC X-Fujinon SW 28mm 1:1.9 DM
• EBC X-Fujinon W 35mm 1:1.9 DM
• X-Fujinon 50mm 1:1.9 DM
• EBC X-Fujinon 55mm 1:1.6 DM
• X-Fujinon 55mm 1:1.6 DM
• EBC X-Fujinon Z 35-70mm 1:2.8-3.7 DM
• EBC X-Fujinon Z 70-140mm 1:4-4.5 DM

The Fujinar lenses are:

• X-Fujinar W 28mm 1:2.8 DM
• X-Fujinar T 135mm 1:2.8 DM
• X-Fujinar Z 80-200mm 1:3.8 DM

The "no-DM" lens cannot be used for program and shutter priority exposure modes of the AX-5 SLR; aperture priority and manual mode will work.

There were some accessories that complied with Fujica X-mount:

• The "mount adapter X-S and X-D" for M42 lenses.
• Two extension tubes : X25 (25 mm) and X50 (50 mm).
• The "auto bellows X" used with a 50 mm lens can provide 1 to 3× 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 8 mm and 16 mm 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".
• Fuji Photo Recorder back. This data back was interchangeable with the standard camera back and was equipped with a hand-writing pen that is inter-linked with a "light pen" for printing in data (up to 80 characters) in the bottom-left corner of the image. The back can be easily detached by pushing down on the hinge pin.
