Free tools
Calculators for planning a shot, built on the gear list Cutvey Viewfinder frames with. Each runs in your browser and needs no signup.
Built on the app's own gear list
Every tool here reads the same camera list Cutvey Viewfinder frames with: 722 camera bodies and 2,309 recording modes, counted November 2, 2026, each mode with the size of its active area. Generic calculators ask for a sensor size, and most camera sensors are not recorded whole. Here you pick the recording mode, so the answer is for the frame you will shoot.
They run in your browser, need no account, send nothing anywhere and store nothing. Your settings live in the page's address, so a copied link opens the same camera and lens for whoever you send it to.
