The firmware update Ver. 2.10 from Ver. 2.00 incorporates the following issues:
1.
Addition of compatibility with "XF18-135mmF3.5-5.6 R LM OIS WR"
To ensure that autofocus performs as expected, upgrade the firmware for the camera.
2.
Change of aperture display for zoom lenses
Display of aperture value when zooming with the shutter button pressed halfway will become same as the display when zooming without the shutter button pressed.
