Both calculators run independently β change the inputs on either side to compare results.
Photography
Field of View Calculator
Calculates the horizontal angle of view in degrees for any focal length and sensor width combination. Use it when choosing a lens for a specific framing or comparing cameras with different sensor sizes.
Fill in the required fields to see your result.
Optics
Depth of Field Calculator
Compute the total depth of field for any camera and lens combination using focal length, f-number, focus distance, and circle of confusion. Use it to plan sharp focus zones before a shoot.
