CineOptix Lens & Lighting Hub

CineOptix is a complete offline camera and lighting calculator for filmmakers, videographers, camera assistants, and photographers. Calculate depth of field, hyperfocal distance, ND filter stops, sensor crop factor, and studio light falloff on set - with no internet connection, no account, and no sign up. Built for real production days: cold sets, dead zones, and no signal. Every calculation runs on your device. DEPTH OF FIELD & HYPERFOCAL DISTANCE Compute near limit, far limit, and total depth of field for any lens and sensor combination. Set focal length, f-stop, and focus distance to preview your sharpness range and bokeh falloff before you roll. The DOF calculator supports Full Frame, Super 35, APS-C, Micro Four Thirds, and Medium Format. Find the hyperfocal distance for maximum sharpness in landscape and wide establishing shots. SENSOR CROP FACTOR MATRIX Convert any lens to its 35mm equivalent focal length in one tap. See the exact field of view angle for your camera body, and compare how the same lens frames differently across sensor sizes. ND FILTER EXPOSURE CALCULATOR Work out the exact shutter speed and aperture compensation for any neutral density filter. Convert between ND numbers, optical density, and stops reduced. Essential for long exposure work, shooting wide open in daylight, and keeping a 180 degree shutter under bright sun. SHUTTER ANGLE CONVERTER Convert shutter angle to shutter speed at any frame rate, from 24 fps to high speed slow motion. Includes flicker free frequency sync for 50 Hz and 60 Hz mains, so you can shoot under HMI, fluorescent, and LED fixtures without banding. STUDIO LIGHTING PHOTOMETRICS Apply the inverse square law to predict light falloff at any distance. Estimate lux and foot candle levels for key light, fill light, and background separation, and work out how far to move a fixture to gain or lose a stop. ANAMORPHIC DE-SQUEEZE SIMULATOR Preview your framing through 1.33x, 1.5x, 1.8x, and 2x anamorphic squeeze ratios. Check the final aspect ratio against 2.39:1 scope, 1.85:1 flat, 16:9, and 4:3 delivery formats before you commit to a lens. RECORDING MEDIA & STORAGE Calculate card and drive requirements from codec bitrate and shooting duration. Plan storage for RAW, ProRes, and compressed 4K and 6K workflows, and know how many minutes fit on a card before the day starts. CAMERA CHECKLISTS Pre production rigging and sensor maintenance checklists saved locally on your device. Prep the camera package, check the lens kit, and log sensor cleaning without a spreadsheet. OPTICAL CALIBRATION Set custom circle of confusion presets to match your own acceptable sharpness standard, and configure units and defaults to match the way you work. WHO IS IT FOR Filmmakers, directors of photography, camera operators, 1st AC and focus pullers, gaffers, videographers, wedding and event shooters, documentary crews, film students, and stills photographers who need fast answers on set. 100% OFFLINE No account. No cloud. No tracking. No network permission. CineOptix works in a basement, on a mountain, and on a plane. All your presets and checklists stay on your device. CineOptix answers questions like: How much depth of field do I have at f/2.8? What is the hyperfocal distance for this lens? Which ND filter do I need? What shutter speed matches a 180 degree shutter at 25 fps? How far should this light be for correct exposure?
