Find out how to pick the right lens for the right situation.
Digital Only vs Full Frames Lenses:Just like camera bodies, camera lenses come designed for full-frame, APS-C-sized, or Four-Thirds-sized sensors. It is important to understand this distinction to ensure compatibility between lenses and a camera.A full-frame sensor is generally 1.5x the size of an APS-C-sized sensor and 2x the size of Four Thirds-sized sensors. For the most part, cameras with APS-C- sized sensors can use both digital-only and full-frame lenses. However, some full-frame cameras (notably Canons) can use ONLY full-frame lenses.
