Focus One-Shot AF In this focus mode, you will focus manually in most situations but still have the option to have the camera focus automatically only once on the subject inside the AF frame. You can change the size and position of the AF 84 frame. 1 Set the focus mode switch on the lens to AF. • On a compatible EF Cinema/broadcast lens, enable automatic adjustment on the lens (A 81). • @ will appear on the left of the screen. 2 Select > [v Camera Setup] > [AF Mode] > [One Shot]. 3 If necessary, change the size and position of the AF frame (A 86). 4 Press and hold the ONE-SHOT AF button. • A white AF frame will appear on the screen and the camera will focus automatically. When you are using Face AF, the face detection frame around the face of the person who has been determined to be the main subject will turn white. • When correct focus has been achieved, the AF frame turns green. If the camera cannot focus automatically, the AF frame will turn red. • The AF frame will disappear when you release the ONE-SHOT AF button. NOTES • One-shot AF will not work in the following cases. - When slow & fast motion recording is activated, if using certain lens models (A 230). - When slow & fast motion recording is activated. - When Face AF is set to [Face Only] and a face has not been detected. • When the aperture value used is F13 or higher, Dual Pixel CMOS AF will not work and the camera will focus using contrast-detection autofocus. AF-Boosted MF In this focus mode, you can focus manually most of the way and let the camera finish focusing automatically. This is very convenient when you want to make certain that high-resolution clips (4K and higher) are in sharp focus. Additionally, with this mode, if the camera cannot evaluate how to adjust the focus, it will not perform unreliable focus adjustments. This results in a more stable focusing operation overall than with continuous AF. 1 Set the focus mode switch on the lens to AF. • On a compatible EF Cinema/broadcast lens, enable automatic adjustment on the lens (A 81). • @ will appear on the left of the screen. 2 Select > [v Camera Setup] > [AF Mode] > [AF-Boosted MF]. • When the focus is in the manual adjustment range, a yellow AF frame will appear on the screen. 3 If necessary, change the size and position of the AF frame (A 86). 4 Turn the focus ring to adjust the focus. • Focus manually to bring the subject closer into focus. When the focus enters the automatic adjustment range, the focus frame will turn white and the camera will then finish focusing automatically. • While the focus stays within the automatic adjustment range, the camera will keep the subject in focus automatically.
