Instantly switching AF area selection modes with a single button

Assigning the AF modes you want to switch is convenient using [Custom Controls]

AF areas instantly with the press of single button without having to move your eye from the viewfinder.

By pressing the 
assigned button

Examples of instantly switching AF area selection modes

Shooting the pit stop in motor sports 
for example. After shooting wide shots 
at the wide angle end of a zoom lens 
with [Single-point AF], quickly zoom 
in, and when targeting the driver's eye 
avoiding the helmet using [Spot AF].

From [Single-point AF] to [Spot AF]

On shooting with optional 'AF area 

selection mode'

Switchable into set 'AF area selection 

mode'

'Switch to registered AF functions' assigns.

An example is soccer etc. where the 
player appear s quite small in the 
viewfinder, then comes closer to fill 
the screen. In this case, by switching to 
[AF point expansion], it is possible to 
steadily track low contrast portions of 
the uniform even as it gets larger.

From [Single-point AF] to [AF point expansion]

Switching to [61-point automatic 
selection AF] is effective with figure 
skating where the skater comes from 
far away to fill up the screen as they 
approach. You can leave AF point 
s e l e c t i o n up to t h e c am e ra, an d 
concentrate on framing as you shoot.

From [AF point expansion] to [61-point automatic selection AF]

AF area selection modes

[Switch to registered AF functions]

There are the two buttons that can be assign to switch AF 
functions. The 

 button and   button can be assigned with 

[Switch to registered AF functions].

Assign [Switch to registered AF functions] to the 

 

button or   button with [Custom Controls]. Press the 

 button on the assign function’s selection screen, 

and from various AF functions, select the [AF area 
selection mode], and select the mode that you want 
to use.

 button 

now

Select the [AF area 
selection mode]

AF area selection modes such as [Single-point 
AF] and [AF point expansion] are effective for 
switching according to the size and type of 
subjects. While looking through the viewfinder 
it can be difficult to change the mode while 
tracking the subject. However, by assigning the 
AF area selection modes you want to use, to 
specific buttons, you can switch instantly while 
continuing shooting. There four buttons that 
can be assigned. Think about the characteristics 

of the sports and subjects you want to shoot 
beforehand, and assign the AF area selection 
modes you think you will use. By assigning 
different modes to each of the four buttons, 
you can control up to four modes at will. In 
addition, aside from the AF area selection 
modes, various functions can be registered and 
applied, so by making settings as needed, you 
have the flexibility to handle conditions as they 
change.
