Macro Photography Calculator

Macro Simulator lets you visualize the physics of macro photography in real time. Pick your camera and lens, set the subject distance, and instantly see how your shot will look — before you ever press the shutter. Three interactive diagrams: - Top-down setup — see the full optical path from sensor to subject, including working distance and depth of field zone - Sensor projection — visualize exactly how your subject maps onto the sensor, whether it fills the frame or gets cropped - Depth of field — see the in-focus zone and how your subject sits within it Real equipment, real physics: - 10 camera bodies from Nikon, Canon, Sony, and Fujifilm (APS-C and full-frame) - 16 macro lenses including 2:1 ultra-macro options from Laowa - Magnification computed from real-world lens data curves, not simplified formulas - Accurate depth of field, effective f-number, and field of view calculations Extension tube simulation: Dial in 0–68mm of extension with snap points at common tube sizes (10, 12, 20, 25, 36, 48, 68mm). See how tubes shift your minimum focus distance and boost magnification. Built for macro shooters: - Box and cylinder subject shapes with custom dimensions - Five unit systems: mm, cm, m, inches, feet - Automatic mount compatibility filtering - Dark and light themes - All settings saved between sessions Whether you're planning a focus stack, choosing between lenses, or figuring out if an extension tube will get you close enough — Macro Simulator gives you the answer instantly.
