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 gear database ships bundled inside the app. Hundreds of lenses and bodies, all searchable. Type '50mm Summicron' and it narrows instantly. Type '50' and everything with a 50mm focal length comes up. You can also filter by brand (Zeiss) or maximum aperture (f/1.4). Every entry carries the full spec: aperture range, shutter type, filter thread, era.
How to find a lens
Open Equipment and tap the Lens picker. Start typing whatever you know: focal length, brand, aperture. The list narrows. Tap the one you own.
Medium-format support
Leaf-shutter glass for Mamiya, Hasselblad, Rolleiflex, and Pentax 67 is in there. If something is missing, Add custom lens covers it.
Offline
Everything is bundled on-device, so there is no waiting on a server. It works on the subway, in the field, anywhere.
