Interchangeable Lens Database

Bundled searchable database of camera lenses including medium-format leaf-shutter glass.

Where to find it

Gear picker Lens search; Equipment modal

Summary

The app ships with assets/gear/lenses.json and assets/gear/cameras.json bundled. The GearRepository loads the data lazily and provides both id-lookup and case-insensitive substring search. The database covers fixed and interchangeable lenses across 35mm and MF bodies, with special support for leaf-shutter lenses.

Detail

How it works

The app includes a searchable database of hundreds of camera lenses and bodies. You can search by name (50mm Summilux), focal length (50), brand (Zeiss), or aperture (f/1.4). Each lens has full specs stored.

How to find a lens

Tap the Lens picker in Equipment. Start typing the lens name or focal length. The results narrow as you type. Tap the one you own.

Medium-format support

The database includes leaf-shutter lenses for Mamiya, Hasselblad, Rolleiflex, Pentax 67, and other MF platforms. If your lens is not in the database, use Add custom lens.

Offline

The lens database is bundled with the app, so it works without internet. No cloud lookup, no lag, no connectivity required.

Implementation notes (for developers)
