Sigma 18-250mm f/3.5-6.3 DC OS HSM Macro APS-C Lens for Canon EF-S Mount {62}

Sigma 18-250mm OS HSM: one lens from wide to telephoto on APS-C.

The 13.9x zoom range of the Sigma 18-250mm f/3.5-6.3 DC OS HSM Macro covers what most shooters would otherwise pack as two or three separate lenses. On a Canon APS-C body, 18mm gives you a workable wide angle for interiors or landscapes, while 250mm reaches far enough for birds at a park or candid moments across a ceremony. That kind of reach in a single barrel is the whole point.

Optical Stabilization keeps the image steady when you're shooting at longer focal lengths with the aperture narrowing toward f/6.3. The Hypersonic Motor drives autofocus quietly and without drawing from the camera body for power, which matters on older Canon EOS bodies that lack in-body focus motors. The macro capability closes the distance on small subjects when you don't want to swap glass mid-shoot.

Native Canon EF mount means it works across Canon's APS-C lineup without adapters, though it can be adapted to Sony E, Canon RF, Nikon Z, Fuji X, and L-Mount systems if your workflow calls for it. For a shooter who wants one lens in the bag and nothing else, this Sigma makes that trade-off without gutting the focal range.

Who It's For

Travel photographers who count every gram will appreciate having 18-250mm covered by a single lens than a two-lens kit. Event photographers working receptions or school functions benefit from the HSM autofocus and OS when the light drops and the action keeps moving. Beginning Canon EOS shooters learning to read light across different focal lengths get a full range to experiment with before committing to primes or dedicated telephotos. Birders and wildlife observers on day hikes who need occasional reach to 250mm without dedicating bag space to a dedicated telephoto will find the macro capability an useful bonus.

FAQ

What focal length range does this lens cover on Canon APS-C?

18-250mm gives you wide angle at 18mm (equivalent to roughly 29mm on full frame) through to 250mm telephoto, a 13.9x zoom that replaces two or three traditional focal lengths.

Does the Hypersonic Motor work on older Canon EOS bodies?

Yes. The HSM autofocus motor is self-powered and doesn't draw from the camera body, so it functions on Canon EOS bodies that lack in-body focus motors.

How close can you focus with the macro capability?

The macro function lets you focus closer than a standard zoom at the same focal length, useful for small subjects without changing lenses mid-shoot. Exact minimum focus distance varies by focal length.

Will Optical Stabilization help at 250mm?

OS is most valuable at longer focal lengths where handholding gets difficult. At 250mm with the aperture at f/6.3, stabilization gives you a few extra stops of handholdability.

Can you use this lens on other camera systems?

It's native Canon EF mount. Third-party adapters exist for Sony E, Canon RF, Nikon Z, Fuji X, and L-Mount, but adapting removes autofocus on most of those systems.

What's the widest aperture at the telephoto end?

The aperture narrows to f/6.3 at 250mm. At the 18mm wide end, you get f/3.5-a typical trade-off for an all-in-one zoom this long.
