a3: Focus Tracking with Lock-On G button ➜ A Custom Settings menu This option controls how autofocus adjusts to sudden large changes in the distance to the subject when AF-C is selected or continuous-servo autofocus is selected when the camera is in AF-A mode for viewfinder photography. Option C 5 (Long)/ ( 4/ D 3 (Normal)/ ) 2/ E 1 (Short) Off Description When the distance to the subject changes abruptly, the camera waits for the specified period before adjusting the distance to the subject. This prevents the camera from refocusing when the subject is briefly obscured by objects passing through the frame. Note that 2, 1 (Short), and Off are equivalent to 3 (Normal) when 3D-tracking or auto-area AF is selected for AF-area mode. The camera immediately adjusts focus when the distance to the subject changes. Use when photographing a series of subjects at varying distances in quick succession. a4: Number of Focus Points G button ➜ A Custom Settings menu Choose the number of focus points available for manual focuspoint selection. Option Description B 51 points Choose from 51 focus points. A 11 points Choose from 11 focus points. Use for quick focus-point selection. 86 Menu Guide
