About the Lens Comparison Tool

What is this tool?

The Lens Comparison Tool is an interactive visualization tool designed to help photographers understand how different focal lengths and crop factors affect field of view. Whether you're planning a shoot, considering a lens purchase, or just learning about photography, this tool can help you visualize the differences between various lens configurations.

By manipulating focal length and crop factor values, you can see exactly how your camera and lens combination will frame a scene. This is particularly valuable when transitioning between camera systems or when trying to achieve specific compositional effects.

Features

• Interactive visualization of focal lengths from ultra-wide to telephoto
• Support for common crop factors (Full Frame, APS-C, Micro Four Thirds, etc.)
• Side-by-side comparison of multiple lens configurations
• Visual representation of field of view angles
• Educational information about common lens uses
• Responsive design that works on desktop and mobile devices

How to Use

Using the tool is simple:

1. Select a focal length using the dropdown or enter a custom value
2. Choose a crop factor that matches your camera
3. Add additional lens configurations to compare side by side
4. Observe how each lens would "see" the scene

The rectangles represent the field of view for each lens configuration. The larger the rectangle, the wider the field of view.
