Canon cameras & lenses — more brands coming soon

Stop guessing if your gear works together.

Altoscope cross-references thousands of cameras, lenses, and accessories so you always know what's compatible — before you buy or rent.

Everything you need to know, in one place.

Our data pipeline scrapes manufacturer specs and normalises them into a structured database you can actually query.

Select a camera body and a lens to instantly see whether they share a mount, whether an adapter is needed, and what features you'd lose.

Every spec — sensor size, mount type, focal length, aperture range — is stored as typed, queryable data, not a blob of HTML.

Canon EF, RF, CN-E, and EF Cinema lenses today. Nikon Z, Sony E, and ARRI PL support shipping soon.

Browse spec sheets for every camera body and lens with images, section-grouped specs, and links to official documentation.

Our automated scraping pipeline re-runs on demand to catch newly released products and spec corrections.

Whether you're renting for a shoot or building a kit, get a definitive answer before money changes hands.
