The lens trinity is a set of three zoom lenses that cover a wide range of focal lengths, from wide-angle to telephoto.

Typically, the lens trinity consists of a 16-35mm f/2.8, a 24-70mm f/2.8, and a 70-200mm f/2.8 lens.

These lenses are designed to deliver high image quality, fast autofocus, and low light performance.
