Photography & Lenses Calculators

Take creative and technical control of your images with our suite of photography calculators. These tools help you understand the relationship between your camera, lens, and subject to master concepts like depth of field, field of view, and exposure.

For Educational & Planning Purposes: These calculators are based on standard optical formulas and provide excellent estimates for planning your shots. Always trust your camera's viewfinder and live view for final composition and focus.

Depth of Field (DoF) Calculator

Calculate the near limit, far limit, and total depth of field to control what parts of your image are in sharp focus.

Field of View (FoV) Calculator

Determine the angular field of view for any lens and sensor combination to understand how much of the scene your camera will capture.

Hyperfocal Distance Calculator

Find the hyperfocal distance for your lens setup to maximize depth of field, a crucial technique for landscape photography.

Equivalent Focal Length Calculator

Compare lenses across different camera sensor sizes by calculating the equivalent focal length (e.g., from APS-C to Full Frame).

Exposure Value (EV) Calculator

Calculate the Exposure Value (EV) for a given set of aperture, shutter speed, and ISO settings, or find equivalent exposures.
