Dual-axis autofocus sensors revolutionize sharpness in challenging shots
9 days ago
0
Why do cross-type autofocus points provide better focusing performance compared to single-axis points?
Because they use manual adjustment instead of sensors to focus.
Because they detect contrast in both horizontal and vertical directions, improving accuracy.
Because they only detect contrast in one direction, making them faster.

How does through-the-lens metering improve exposure accuracy compared to external light meters?
It uses a separate sensor outside the lens to measure ambient light more broadly.
It measures the light that actually passes through the camera lens, accounting for lens characteristics and filters.
It estimates exposure based on the camera's internal settings without measuring light.
