What sensor formats are supported?

The tool supports Full Frame, APS-C, Micro Four Thirds (M4/3), and 1-inch sensors.

How do I calculate the crop factor?

You can use the `get_sensor_equivalence` tool to automatically calculate the crop factor and the Full Frame equivalent focal length.

Does this account for vertical field of view?

No, this tool specifically focuses on the horizontal Field of View (FOV) calculations.

This MCP server provides precise mathematical conversions between horizontal Field of View (FOV) in degrees and lens focal length in millimeters. It supports multiple sensor formats including Full Frame, APS-C, Micro Four Thirds (M4/3), and 1-inch sensors. Use calculate_focal_length_from_fov to find the required lens for a specific angle, calculate_fov_from_focal_length to predict your view, or get_sensor_equivalence to understand crop factor magnification.
