How to Use the Camera Sensor Size Comparison Tool

📖 How to Use the Camera Sensor Size Comparison Tool

Select your first and second sensor formats from the dropdown menus (or enter custom dimensions).
Enter a lens focal length (e.g., 35mm) and choose which sensor it’s mounted on.
Click Compare to see:
- Sensor dimensions and diagonals.
- Relative size and crop factor.
- Field of view (horizontal, vertical, diagonal).
- 35mm full-frame equivalent focal length.
- The focal length needed on the other sensor for the same framing.

Tip: This tool is great for comparing APS-C vs Full Frame, Micro Four Thirds vs Super 35, or even custom sensors in cinema cameras.

Choosing the right sensor size is one of the most important decisions in photography and cinematography. Different formats — from Full Frame, APS-C, and Micro Four Thirds to Super 35 and Medium Format — change how your lenses behave, altering both field of view and depth of field perception.

The Camera Sensor Size Comparison Tool makes it easy to compare two sensors side by side. Simply select your sensor formats, enter a lens focal length, and the calculator will show the effective field of view, diagonal size difference, crop factor, and 35mm equivalent focal length. For example, a 35mm lens on APS-C (1.5× crop) behaves like a ~52mm lens on Full Frame, while the same lens on Micro Four Thirds (2× crop) behaves like ~70mm.

This tool is especially useful for:

Photographers switching systems and wanting to know how their lenses translate across formats.
Cinematographers balancing lens kits across Super 35 and Full Frame cameras.
Content creators choosing between compact Micro Four Thirds setups and larger full-frame rigs.
Students and beginners learning why the same lens looks “different” on smaller sensors.

By using this calculator, you’ll eliminate guesswork, avoid mismatched lenses, and plan your kit with precision. Whether you’re shooting a landscape, portrait, or cinematic scene, this tool ensures you understand exactly how your lenses behave on different camera bodies.
