Canon Image Stabilizer Zoom Lens EF-S 18-135mm 1:3.5-5.6 IS STM

Description

The used Canon EF-S 18-135mm f/3.5-5.6 IS STM is one of the most practical all-in-one zoom lenses Canon has produced for APS-C format DSLRs — and this example, available from Good Used Cameras on Vancouver Island, BC, is in excellent condition with clean glass and fully confirmed autofocus and Image Stabilizer operation. If you shoot with a Canon EOS Rebel, 60D, 70D, 77D, 80D, or any other EF-S compatible body and want a single lens that handles the widest range of shooting situations, this is a compelling choice at a used price.

The Case for the 18-135mm Focal Range
At 18mm you have genuine wide-angle coverage — broad enough for landscapes, interiors, group portraits, and environmental storytelling. Zoom to 135mm and you have solid telephoto reach for isolating subjects, compressing backgrounds, shooting across a room, or pulling in distant details on a travel day. On a Canon APS-C sensor with its 1.6x crop factor, that translates to a 29–216mm full-frame equivalent — a range that covers the vast majority of everyday shooting scenarios without ever changing lenses. For travel photographers, event shooters, and enthusiasts who want one capable lens rather than a bag full of glass, the 18-135mm is a well-proven solution.

The defining upgrade in this 2012 version over the original 18-135mm IS is the introduction of Canon’s Stepping Motor (STM) autofocus system. STM drives the focus elements using a smooth, near-silent motor that is specifically engineered for continuous autofocus during video recording. On bodies that support Movie Servo AF — including the EOS 70D, 80D, and Rebel T4i and later — the STM motor tracks subjects during video with minimal noise and fluid, cinematic focus transitions. For still photographers, STM delivers quick and accurate autofocus with full-time manual override. This lens genuinely serves double duty for hybrid shooters who move between stills and video.

Optical Design
Canon engineered the 18-135mm IS STM with 16 elements in 12 groups, incorporating one UD (Ultra-low Dispersion) glass element to control chromatic aberration and one glass-mold aspherical element to reduce spherical aberration and distortion. Canon’s Super Spectra coating is applied to minimize flare and ghosting when shooting in strong light or backlit conditions. An inner focusing system keeps the front element stationary during focus, which is helpful when using circular polarizing filters. The 7-blade circular diaphragm produces smooth, rounded bokeh in out-of-focus areas.

Image Stabilization
The IS system in this lens provides up to 4 stops of shake compensation, based on CIPA standards. In practical use, this means noticeably sharper handheld results at the telephoto end — particularly valuable when shooting in lower light or at events where a tripod isn’t practical. The IS system also supports Dynamic IS mode on compatible Canon bodies for smoother video while walking or moving with the camera.

Compatibility Note
This is a Canon EF-S mount lens designed exclusively for APS-C format Canon DSLRs. It is not compatible with Canon full-frame (EF) bodies such as the 5D or 6D series. It will mount on EF-S bodies only: EOS Rebel series, EOS 60D, 70D, 77D, 80D, 90D, and equivalent. Do not attempt to mount this lens on a full-frame Canon EOS body.
