Canon RF-S 18-150mm f/3.5-6.3 IS STM Autofocus APS-C Lens for RF-Mount, Black {55}

Canon RF-S 18-150mm f/3.5-6.3 IS STM: one lens, 29-240mm equivalent reach.

At 310g and 5 inches long, this is the lens that stays on your R7 or R10 when you don't want to think about swapping glass. The 8.3x zoom range covers 29-240mm equivalent, meaning you can shoot an environmental portrait at 18mm and pull in distant detail at 150mm without touching your bag. That kind of range in a single, compact package is what makes it the default choice for travel, documentary work, and run-and-gun video.

The optical formula, 17 elements in 13 groups, with one UD element and two aspherical lenses, keeps aberrations controlled across that wide range, and Canon's Super Spectra Coating handles ghosting and flare in contrasty light. Closest focus of 0.17m at 18mm and a 0.44x maximum magnification at 50mm give you genuine close-up capability without a dedicated macro lens. On native APS-C bodies like the R7 or R10, Dual Pixel CMOS AF covers the full 100% x 100% of the frame, and the leadscrew STM motor keeps focus transitions silent during video recording.

The 4.5 stops of optical IS is useful on its own; paired with a body that supports Coordinated IS, that figure climbs to 6.5 stops. For low-light handheld shooting, that margin is significant. The 55mm filter thread is common enough to share glass with other lenses, and the dual-function control ring can be assigned to aperture, ISO, or exposure compensation depending on how you work.

Who It's For

Travel photographers carrying one body and one lens will find the 29-240mm equivalent range handles architecture at 18mm and candid street moments compressed at 150mm without a second thought. Video creators shooting on the R7 or R10 get 100% Dual Pixel CMOS AF coverage and STM's silent focus drive, which keeps ambient audio clean in interviews or quiet environments. Documentary shooters working in available light benefit from the 4.5-stop IS, or 6.5 stops with a compatible IBIS body, to keep footage stable without a gimbal. The 0.44x magnification at 50mm also suits product or detail work when a dedicated macro isn't practical.

FAQ

What's the actual reach of this lens on an R7 or R10?

29-240mm equivalent. That's wide enough for environmental portraits at 18mm and long enough to pull detail at 150mm without cropping in post. On full-frame bodies, the camera crops automatically to 1.6x, so you get the same effective coverage.

How does the autofocus perform during video?

The STM motor is silent. It's designed specifically for video work where you can't afford focus hunting noise bleeding into your audio track. Still shooting gets responsive, quick AF as well.

Can you focus closer with this lens?

Yes. Minimum focus is 0.17m at 18mm, and the 0.44x magnification at 50mm gives you genuine close-up work without adding a macro lens. Your field of view at minimum focus is roughly 51mm x 34mm at 50mm.

What's the stabilization story here?

Optical IS delivers 4.5 stops on its own. Pair it with an R7, R10, or R5 that supports Coordinated IS, and you're at 6.5 stops. That margin matters when you're handheld in low light without climbing ISO.

Does this work on full-frame EOS R bodies?

It does. The camera automatically crops to 1.6x when you mount it, so you get the same 29-240mm equivalent reach. AF coverage drops to 80% x 80% in that mode, versus 100% x 100% on native APS-C bodies.

What about build quality and weather sealing?

No weather sealing on this lens. It's compact and travel-friendly, not built for harsh environments. The 17-element, 13-group optical design with UD glass and aspherical elements prioritizes optical performance and weight.

Can you manually focus during AF?

Yes. Full-time manual focus is available. The electronic ring has no physical limit to rotation, and you can flip between AF and manual in the camera menu without a physical switch on the lens.
