The Canon EOS 5D Mark IV features a professional-grade (with up to 41 cross-type points) designed to deliver high precision even in challenging conditions. It incorporates Dual Pixel CMOS AF , which provides smooth and fast continuous focusing during Live View and video recording, covering approximately 80% of the image area. Core AF Performance Features
A hybrid mode where the camera automatically switches from One-Shot to AI Servo if it detects the subject suddenly starts moving. Generally, professional photographers avoid this mode as it can be less predictable than manual selection. 4. Tuning Your Focus with AF Cases (AI Servo Customization)
Adjusts how the camera responds to rapid speed changes. Increase this value for sudden stop-and-start movements.

To get the most out of the Canon 5D Mark IV's autofocus system, it's essential to understand how to use it effectively. Here are a few techniques to help you improve your focusing:
The Custom Functions menu features six pre-programmed tracking presets called "Cases." These fine-tune the AI Servo AF behavior based on how your subject moves. Case Preset Best Used For Key Behavior General purpose Versatile, basic settings for standard moving targets. Case 2 Tennis, swimming
The focus grid covers a wider area of the frame compared to its predecessor, allowing for better off-centre compositions without needing to recompose. 2. Choosing the Right AF Area Selection Mode The Canon EOS 5D Mark IV features a
Uses a primary focus point surrounded by four helper points (above, below, left, right). Ideal for tracking slightly erratic subjects like a runner.
The opposite of Case 2. It instructs the camera to instantly switch focus to any new subject that crosses the focus point. Perfect for skate parks or ski racing.
Designed for sports like basketball, soccer, or erratic wildlife where subjects stop and start aggressively. Generally, professional photographers avoid this mode as it
All 61 points remain active, and 21 of them stay cross-type. This is a massive upgrade over older bodies that limited f/8 focusing to just the center point. 2. Choosing the Right Focus Mode You must match your focus mode to your subject's movement. One-Shot AF
Digital cameras and lenses have tiny manufacturing tolerances. If your lens is consistently front-focusing or back-focusing, use the AF Microadjustment feature in the utility menu to fine-tune the calibration for each specific lens.
When you switch to the LCD screen, the camera bypasses the traditional AF sensor and uses the imaging sensor itself. Every single pixel on the 30.4-megapixel sensor consists of two photodiodes. The camera compares the light hitting these photodiodes to calculate phase-detection autofocus instantly. This results in incredibly smooth, cinema-grade tracking and eliminates the need for lens micro-adjustments in Live View. 2. Choosing the Right AF Area Selection Mode
