Canon EF-S 18-135mm f/3.5-5.6 IS STM Autofocus APS-C Lens, Black {67}

Canon's 18-135mm STM: the APS-C one-lens travel solution.

a 18-135mm range on an APS-C body translates to a 29-216mm equivalent, which covers wide interiors, street portraits, and distant subjects without swapping glass. That kind of reach in a single barrel makes this lens the practical choice when changing lenses isn't an option. The STM stepping motor drives autofocus with the smooth, near-silent operation that video shooters need, and the 4-stop optical image stabilization keeps handheld frames steady even in dim light. Dynamic IS goes a step further, compensating for the compound motion of walking with a camera, not just rotational shake.

For photographers shooting on Canon APS-C bodies, Rebels, 90D, 7D series, this lens sits on the camera and stays there for most outings. The 67mm filter thread is a common size, so a single circular polarizer or ND filter serves the whole kit. It won't replace a dedicated telephoto or a fast prime, but as a foundation lens that handles most real-world shooting situations, the 18-135mm STM has a well-earned place in the system.

Who It's For

Travel photographers get a 29-216mm equivalent in one lens with 4-stop stabilization, which matters when shooting handheld in variable light across many scenes in a day. Videographers using Canon APS-C bodies benefit from the STM motor's quiet focus transitions and Dynamic IS that reduces the jitter of handheld movement. Event shooters who need flexibility between room-wide group shots and tighter candid framing will find the zoom range covers both without a mid-event lens change. It also works well for newer photographers building a first kit around a single capable zoom before adding specialty glass.

FAQ

What's the 35mm equivalent focal length for APS-C bodies?

29-216mm. On a Canon Rebel, 90D, or 7D, this lens covers wide interiors at 29mm and extends to a 216mm telephoto equivalent for distant subjects without a focal length converter.

How does STM autofocus differ from Canon's older AF motors?

STM uses a stepping motor for near-silent, smooth focusing - essential for video work where AF noise gets recorded. It's faster and quieter than older Canon AF designs but trades some continuous tracking speed you'd get from a standard USM motor.

Does Dynamic IS really work for handheld video?

Yes. Standard IS corrects rotational shake; Dynamic IS compensates for the compound motion of walking with a camera. It's noticeably smoother than optical IS alone when you're moving and filming.

Can you use the same filters across your kit with this lens?

The 67mm filter thread is standard enough that a single circular polarizer or ND filter works here and across most other mainstream zoom lenses, reducing redundant purchases.

Is 4 stops of IS enough for handheld shooting in low light?

At f/3.5 on the wide end, yes. At 135mm and f/5.6, you're pushing it below ISO 400 in dim interiors without a tripod, but the 4-stop stabilization keeps shutter speeds manageable for most daylight and indoor ambient-light work.

Does this lens have aspherical elements?

Yes. PMo aspherical and UD lens elements correct aberration and reduce size and weight compared to designs using only spherical glass.
