Focus Points Quiz

What happens when you leave your camera set to automatic focus point selection?

The camera always focuses on the subject's eyes

The camera picks what it thinks is the main subject, which often means it focuses on the closest or highest-contrast object instead of your intended subject

The camera disables autofocus

The camera uses all focus points simultaneously for maximum sharpness

What is single-point AF best used for?

Fast-moving wildlife flying toward you

Stationary or slow-moving subjects where you need precise control over exactly where focus lands

Large groups of people

Situations where the subject fills the entire frame

What is the difference between AF-S (Single) and AF-C (Continuous) autofocus modes?

AF-S is for Sony cameras and AF-C is for Canon cameras

AF-S locks focus once when you half-press the shutter, while AF-C continuously adjusts focus to track a moving subject

AF-S uses the center point and AF-C uses all points

AF-S is faster and AF-C is more accurate

Where should you place the focus point for a portrait?

On the subject's forehead

On the nearest eye of the subject

On the tip of the nose

On the background behind the subject

What is back button focus, and why do many photographers prefer it?

Using a button on the back of the camera to lock white balance

Assigning autofocus to a rear button instead of the shutter button, separating the focus and shutter actions so you can focus once and recompose without refocusing

Focusing the lens by turning a dial on the back of the camera

A method of manual focus that uses the rear LCD screen

What is 'focus and recompose,' and what is its potential problem?

It is a technique where you focus on your subject, then move the camera to recompose, but at wide apertures the focus plane can shift enough to miss the subject

It is a method of refocusing after every shot

It only works with manual focus lenses

It is a technique used exclusively in video production

What is eye-detection autofocus, and why is it considered a breakthrough?

It detects when the photographer blinks and pauses shooting

The camera automatically identifies and locks focus on the subject's eye, solving the most critical focus challenge in portrait photography

It adjusts the viewfinder diopter to match the photographer's eyesight

It measures the color of the subject's eyes for white balance

When should you use a group or zone AF area instead of single point?

For still life photography

When you need to track a moving subject that is hard to keep on a single point, like a running child or a bird in flight

Only in manual mode

When shooting at very small apertures

Why are cross-type focus points generally more reliable than linear focus points?

Cross-type points can detect contrast in both horizontal and vertical directions, making them more accurate with a wider range of subjects

Cross-type points are physically larger on the sensor

Cross-type points work only in bright light

Linear points are more accurate but slower

What is focus trapping or trap focus?

A way to lock focus on a preset distance so the camera fires only when a subject moves into that focus zone

A technique for catching subjects in a net before photographing them

Using two cameras to focus on the same subject

A type of focus motor that grabs the subject instantly
