The RF-S 18-150mm covers wide landscapes to distant details. Canon designed it for its APS-C RF bodies, such as the EOS R50 on our mirrorless shelf, and it replaces a two-lens kit.
Read both apertures
The aperture is f/3.5 at 18 mm and f/6.3 at 150 mm. That second figure decides what the lens can do in a dim room or at dusk: at full zoom, it needs light or a higher ISO.
Stabilization and video
Canon rates the optical IS at up to 4.5 stops, rising to 6.5 with an IBIS body. Dynamic IS steadies walking video at the wide end, and the STM motor focuses quietly.

What people ask before they commit
Does it work on a full-frame Canon?
Yes, but the camera crops automatically to the APS-C area, so you lose resolution. It is designed for APS-C RF bodies.
How many stops of stabilization does it give?
Canon quotes up to 4.5 stops, and up to 6.5 with an EOS R body that has in-body stabilization. The listing does not name the test protocol, so treat these as maker figures.
What does 18-150mm mean on an APS-C body?
An equivalent focal length is a calculation: it describes the field of view on a full-frame camera. The focal length engraved on the lens never changes. On Canon APS-C, 18-150 mm frames roughly like 29-240 mm on full frame.
