FocalViz

iPhone / Photo et vidéo

Discover how you actually use your lenses.

FocalViz analyzes the EXIF data in your photos to show which focal lengths and lenses you use most — so you can make smarter decisions about your camera gear.

See your shooting patterns at a glance
A clear, color-coded chart shows exactly how your photos are distributed across focal lengths. Instantly see if you shoot more at 24mm or 200mm, and which lens you reach for most.

Understand every lens in your bag
Each lens gets its own color and focal range indicator, so you can see where your lenses overlap and where the gaps are. Zoom lenses show their full range. Extenders are tracked separately. Primes stand out clearly.

Full frame equivalent display
All focal lengths are converted to their full frame (35mm) equivalent, so you can meaningfully compare shots across different sensor sizes — APS-C, Micro Four Thirds, medium format, and more — all on one chart. Lens range indicators are adjusted to match.

Works with any camera
Canon, Nikon, Sony, Fujifilm, Pentax, Leica, Hasselblad, Phase One, Olympus, Panasonic — plus iPhone, DJI drones, GoPro, and more. If it writes EXIF data, FocalViz can read it.

Filter by camera body
Toggle camera bodies on and off to compare lens usage across different cameras. See how the same 50mm lens performs on your full-frame vs crop body.

Apple Photos integration
Analyze any album in your Photos library — including albums nested in folders. No exporting or file management needed.

Click any bar to see your photos
Tap a focal length in the chart to see thumbnail previews of every photo taken at that distance. A quick way to revisit your best work at each focal length.

Your data stays on your Mac
FocalViz runs entirely offline. No cloud, no uploads, no accounts, no tracking. Your photos and EXIF metadata never leave your device.

Supports all major formats
JPEG, HEIC, TIFF, RAW (CR2, CR3, NEF, ARW, RAF, DNG, and more).

Compatibility
FocalViz has been tested with cameras and lenses from Canon, Nikon, Sony, Fujifilm, Pentax, Olympus, Leica, and more. If your camera or lens information isn't appearing correctly, visit focalviz.com and let us know — we'll update the app to support it.
