: Essential for moving subjects like sports or wildlife. The camera continuously tracks and refocuses as long as the shutter is pressed halfway. AI Focus AF
: An automatic mode that switches from One-Shot to AI Servo if it detects subject movement. It is often considered less predictable than manual selection. AF Area Selection Modes

Select your focus mode based on the movement of your subject:
One Shot AF: Best for stationary subjects like landscapes or architecture. The camera locks focus when the shutter is half-pressed.
AI Servo AF: Essential for moving subjects. The camera continuously tracks and re-acquires focus as long as the shutter is half-pressed.
AI Focus AF: A hybrid mode that automatically switches between One Shot and AI Servo if the camera detects a stationary subject has started moving. Autofocus Area Options
The 5D Mark IV offers several "Selection Areas" to control which of the 61 points are active: The Canon EOS 5D Mark IV features an
Single-point Spot AF: A very narrow area for pinpoint accuracy, such as focusing on a subject's eye through a busy foreground.
Single-point AF: The standard manual selection mode for general use.
AF Point Expansion (4 or 8 points): Uses surrounding "helper" points to maintain focus if your subject moves slightly off the center point. Ideal for sports and wildlife.
Zone AF: Groups points into nine selectable zones. The camera chooses the focus within that zone, useful for larger moving subjects.
Large Zone AF: Similar to Zone AF but covers a broader area of the frame.
61-point Automatic Selection: The camera uses all 61 points and its 150,000-pixel RGB+IR metering sensor to track subjects automatically, prioritizing faces if enabled. Advanced AF Customization
To fine-tune performance for specific action types, use the AF Case Studies found in the first AF menu tab: Case 1: Versatile multi-purpose setting.
Case 2: Continues to track subjects, ignoring potential obstacles. Case 3: Instantly focuses on subjects that enter AF points. Case 4: For subjects that accelerate or decelerate rapidly. Case 5: For erratic subjects moving in any direction.
Case 6: For subjects that change speed and move erratically. Quick Tips & Shortcuts
