Product Overview

A mount adapter that allows the use of a wide variety of M Mount lenses on the X Mount camera body.
It is built with a three-part structure that uses optimum materials for each of the components, to accommodate perfect fitting with high precision.

The adapter also features electronic contacts for communicating signals with the camera body and a function button to allow users to easily choose necessary settings and functions (Shoot Without Lens, focal length settings, various image corrections, etc.). *
The bright frame, shown in the Optical Viewfinder mode, changes according to the defined focal length for easy shooting. **

  • * Requires a user firmware update.
    The applicable firmware will be available from early June.
  • ** The frame may not be displayed for lenses of particular focal lengths.

Signal contacts and the new Function Button for easy shooting

  • When the camera body recognizes the signal contacts of the Mount Adapter, the "Shoot Without Lens" mode is activated automatically.
    Users do not have to go to the MENU screen in order to change this setting, enabling them to start shooting instantly.
  • Pressing the Function Button brings up the Mount Adapter Setting mode instantaneously. This provides ease of operation when registering a new lens to use, entering its settings or changing a lens.

High precision design

The Mount Adapter is designed to maintain the flange back distance of 27.8mm *** for high precision M Mount lenses with advanced planarity.
It is constructed using a three-part structure that employs optimum materials for each of the components.
The contact surface with M Mount lenses features the same high quality stainless steel finish as that used on the X Mount camera body, while the contact surface with the camera body uses an aluminum component similar to that used in XF lenses.
The middle section is made of aluminum to achieve an all-metal construction for a high level of rigidity and durability.

Various image corrections and focal length settings in order to bring out the appeal of these legendary lenses

Mount Adapter Settings that allow up to 6 patterns to be registered

The camera body has four preset focal lengths (21mm, 24mm, 28mm and 35mm) and can store two additional focal lengths.
For each of the six focal lengths, users can define three image correction settings (distortion, peripheral illumination and color shading).

Three types of detailed image correction settings

Users can fine-tune "distortion", "peripheral illumination" and "color shading" according to individual lens characteristics. *4
This feature allows users to correct images according to each lens's optical profile, or opt for settings that accentuate a particular lens characteristic in order to enjoy a unique image quality and style.

  • *4 These image correction functions are only applied to taken photos.
    Live images on the LCD monitor and those viewed through EVF will not be presented as corrected images.
    Please do a test shooting and check the taken photos applied with the correction to find and register the optimum correction setting.
Distortion correction

This function corrects distortion, prominent on the edges of the frame.
It is designed to correct "barrel distortion" typically seen with wide angle lenses and "pincushion distortion" common with telephoto lenses.
Users may select three levels of correction ("Strong", "Medium", "Weak") or "OFF" for both "barrel distortion" and "pincushion distortion".

  • Barrel distortion
  • When correction is turned ON
  • Pincushion distortion
  • When correction is turned ON
Peripheral illumination correction

This function corrects peripheral illumination, i.e. darkening of the four corners of an image.
Users can opt to darken the periphery on purpose to highlight the photo subject at the center in order to enjoy unique image description and flavor.
The correction can be applied on the scale of 11 levels from -5 to +5 (including 0).

  • When correction is turned OFF
  • When correction is turned ON
Color shading correction

"Color shading" is a gradual shift of color between the center and periphery of an image.
This "color shading" function can correct the four corners separately.
-Red / Cyan... The red / cyan color shading is corrected between -9 and +9 relative to the green channel.
-Blue / Yellow...The blue / yellow color shading is corrected between -9 and +9 relative to the green channel.

  • When correction is turned OFF
  • When correction is turned ON

Gauge for confirming lens compatibility

The product package contains a gauge made of resin that allows the user to check the compatibility of M Mount lenses with the adapter.

  • * Some lenses may not be suitable for the adapter even if the gauge indicates them to be compatible.
Please see here for the list of compatible lenses confirmed by Fujifilm.
