DoF Visualizer
DoF Visualizer — See Your Depth of Field Before You Shoot
Stop guessing what will be in focus. DoF Visualizer turns the math of depth of field into a clear, interactive diagram so you can plan your shot with confidence whether you're framing a portrait, isolating a subject, or chasing edge-to-edge sharpness in a landscape. Drag the sliders and watch the field of view, focus zone, and subject distance update in real time. Switch sensor formats to instantly see how the same lens behaves on Micro 4/3, APS-C, Full Frame, or Medium Format.
FEATURES
- Live visual diagram - A clean overhead view of your camera's field of view, the in-focus zone, and your subject distance.
- Real lens range - Choose from 8 mm fisheye to 1200 mm super-telephoto, using focal lengths real lenses are actually built for.
- Full aperture range - f/1.4 through f/22, with depth of field updating as you move.
- Four sensor formats - Micro 4/3, APS-C, Full Frame, and Medium Format, each using the correct circle of confusion.
- All the numbers you need - Angle of view, near focus, far focus, depth of field, and hyperfocal distance, calculated instantly.
- Designed for photographers - Intuitive controls, no clutter, no setup. Just open it and start exploring.
WHO IT'S FOR
- Portrait photographers picking the right aperture for a creamy background.
- Landscape shooters dialing in hyperfocal distance.
- Videographers planning subject separation.
- Students learning how focal length, aperture, sensor size, and distance interact.
- Anyone shopping for a new lens who wants to see exactly what it'll do.
Built natively for iOS with a fast, fluid SwiftUI interface. Take the guesswork out of focus - and start seeing depth of field the way your lens does. Previews and Screenshots
