1. What is Lens Angle Resolution?

The lens angle resolution determines the angular field of view of a camera lens based on the sensor size and focal length. It helps photographers and videographers understand how much of a scene will be captured.

2. How Does the Calculator Work?

The calculator uses the lens angle formula:

Where:

• \( \text{sensor\_size} \) — Diagonal size of the camera sensor (mm)
• \( \text{focal\_length} \) — Focal length of the lens (mm)

Explanation: The formula calculates the angle whose tangent is equal to the ratio of sensor size to focal length, giving the angular field of view.

3. Importance of Lens Angle Calculation

Details: Knowing the lens angle helps in selecting the right lens for a particular shot, understanding field of view, and planning camera setups for photography or videography projects.

4. Using the Calculator

Tips: Enter the sensor size (typically the diagonal measurement) in millimeters and the focal length of the lens in millimeters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between horizontal and diagonal angle of view?
A: The diagonal angle is typically larger as it measures corner-to-corner. Horizontal angle is narrower as it measures side-to-side.

Q2: How does sensor size affect the angle of view?
A: Larger sensors with the same focal length will produce a wider angle of view compared to smaller sensors.

Q3: Why is focal length important for angle of view?
A: Longer focal lengths (telephoto) produce narrower angles of view, while shorter focal lengths (wide-angle) produce wider angles.

Q4: How accurate is this calculation?
A: This provides a theoretical calculation. Real-world results may vary slightly due to lens design factors.

Q5: Can I use this for zoom lenses?
A: Yes, but you need to calculate for specific focal lengths as zoom lenses have variable focal lengths.
