X-Trans II CMOS, e.g. X-T1, X-T10, X-E2 and X-E2s，use central 3 x 5 among all 77 focus points.

Whatever you set AF mode to AF-S or AF-C, single point or zone, the use of focus points outside the

dashed box will activate CDAF and AF performance may be degraded. For X-Trans IV (e.g. X-T3, X-T30,

X-Pro3, X-T4 and X-S10), all the AF points covering the entire sensor support PDAF. Thus, you may use

any of them and get optimal performance. And WIDE/TRACKING mode also works.

Under the single point AF mode, setting the focus point to medium size is recommended for a

better AF successful rate and accuracy. Remember, small size focus point means contrast AF only and

may cause degraded performance.

For cameras equipped with X-Trans IV CMOS, e.g. X-T3, setting the camera to boost mode may

degrade AF performance. The camera may prefer CDAF instead of PDAF under certain circumstances

in that mode. If that happens, please turn off the performance boost mode.

We have tried our best to make F mount lenses work better on X mount. But please understand

that different lens and camera systems will never collaborate like a native system. Sometimes even

lenses optimized may encounter AF issues. You may try to improve its accuracy by half pressing

shutter release button more than once before releasing the shutter. Or you may try AF-C in addition to

AF-S mode. If necessary, please change to the MF mode.

You may change it to the MF mode by turning AF/MF switch on the lens to the MF position. The

camera will be set to the MF mode automatically.

For lenses not in the optimized lens list, PDAF doesn't work. Thus, you may encounter slow and

inaccurate AF. Sometimes MF would be the only choice.

3.4 Lens built-in IS (VR/OS/VC) and camera IBIS functions

This product can activate image stabilizing functions of lenses with VR, OS or VC. When the IS

switch on the lens is turned on, the lens' IS function is controlled by "IS MODE" menu item. If it's set to

"Continuous" (Mode 1), IS function is activated all the time. That may consume more power. When it's

set to "Shooting only" (Mode 2), IS function is enabled when the shutter release button being

half-pressed and disabled about 1 second after its release.

Be noted,

⚫ When IS mode is set to "Continuous", please only turn on the IS switch when necessary to save
