Fujifilm’s new con­tin­u­ous AF ex­plained

Fujifilm’s new con­tin­u­ous aut­o­fo­cus set­tings ex­plained

HWM (Singapore) - - Contents - by Mar­cus Wong

Two of Fujifilm’s lat­est cam­eras – the X-T2 and the X-T20 now use an improved al­go­rithm for con­tin­u­ous aut­o­fo­cus to boost the ac­cu­racy of sub­ject track­ing. Five pre­sets are avail­able for both cam­eras, with the X-T2 al­low­ing you a sixth op­tion – a cus­tom pre­set of your own choos­ing.

Ev­ery pre­set has a set of three slid­ers – Track­ing sen­si­tiv­ity, Speed track­ing sen­si­tiv­ity, and Zone area switch­ing – so here’s what each one means:

Track­ing sen­si­tiv­ity – This set­ting af­fects how closely the cam­era fol­lows your ini­tial sub­ject, let­ting you tell the cam­era how long to wait for a sub­ject to reap­pear. This ranges from 0 to 4, and set­ting 0 makes the cam­era switch fo­cus im­me­di­ately, while set­tings from 1 to 4 in­crease the amount of time it waits.

Speed track­ing sen­si­tiv­ity – This set­ting tells the cam­era how of­ten your sub­ject is chang­ing speed. This ranges from 0 to 2. 0 means the cam­era ex­pects your sub­ject to be mov­ing at the same speed through­out, while 2 means the cam­era will be ex­pect­ing mul­ti­ple changes of speed and ad­just to com­pen­sate.

Zone area switch­ing – This is only avail­able in Zone AF mode, and lets you spec­ify which part of the frame the cam­era should fo­cus on. There are only three op­tions here: Cen­ter, Auto and Front. As you might guess, Cen­ter keeps fo­cus on the cen­ter of the frame all the time, while Front switches fo­cus to which­ever sub­ject is at the front of the frame when the orig­i­nal sub­ject moves out of it. Auto sim­ply tracks the ini­tial sub­ject.
