When you install a lens that is not on the tested and optimized lens list and power on the camera

for the first time, the adapter may drive lens' AF module to the close end and then to infinity to do a

self-test and calibration. During this procedure, please do not touch the MF ring of the lens. Or you

may interfere with the calibration. If there is something wrong with the self-test procedure, the AF

function may not be in a normal state. If that happens, turning on and then turning off the camera at

once will clear the defective calibration data. Installing another lens and power on the camera will do

the same. There isn't such procedure for any tested and optimized lenses.

3.2 Setting aperture and shutter speed value

Like Fujifilm XC lenses, there is no aperture ring on the adapter. You may use camera's command

dial to set aperture value. Please refer to the camera's manual for more details.

For Nikon AF-D lenses, please set aperture ring on the lens to the minimum position (maximum F

number). Or the lever inside the lens may interfere with that of the adapter when controlling

diaphragm.

You may set shutter speed through the command dials on camera. During view finding, when

environment brightness changes, the lens aperture blades may move frequently with a minor noise

and brightness change of LCD or EVF. It only occurs when both AF and aperture priority are enabled.

That's a unique behavior of the Fujifilm mirrorless. Native XF lenses behave the same. But their

aperture motor moves so fast and silently that you will never notice. However, SLR lenses' aperture

moves slower and noisier. If you want to avoid it, manually set the shutter speed. Of course, you may

still set shutter speed to auto if that's tolerable. Be noted that if "PREVIEW EXP./WB IN MANUAL

MODE" in the camera menu is set to "OFF", the described issue may occur even the shutter

speed is set manually.

Regarding D/G lenses from Nikon and other non-electromagnetic auto lenses from third parties,

there is a mechanical coupling between the lens and the adapter which may bring aperture control

tolerance inevitably. When the camera is metering, if the shutter speed is set to auto, e.g., aperture

priority mode, it may use a different aperture from your setting. That may cause metering tolerance.

To avoid it, you need to set the shutter speed manually so that the camera will use the same aperture

setting when metering.

3.3 Setting AF modes

For a better AF performance, please always use phase detection focus points. See the dashed box

in the following charts (X-Trans II and III only). For cameras equipped with X-Trans III CMOS, e.g. X-H1,

X-Pro2, X-T2, X-T20 and X-E3, use central 7 x 7 among all 91 AF points. For cameras equipped with
