LensLink — Sanity Challenge Path One

LensLink is an AI camera compatibility agent developed for the Sanity Challenge Path One. Instead of relying on general AI knowledge, it utilizes structured Sanity content to determine if a lens works with a specific camera. The system models complex relationships between cameras, mounts, lenses, adapters, and compatibility rules. Users can verify direct compatibility, identify when an adapter is required, or discover unsupported combinations, such as using a Canon EF-M 22mm f/2 STM on a Canon EOS R5.
