Canon EF-S 10-18mm f/4.5-5.6 IS STM Autofocus APS-C Lens, Black {67}

Canon's lightest ultra-wide zoom for APS-C shooters.

At 240 grams and 2.83 inches long, this 10-18mm covers a 16-28.8mm equivalent field of view without adding meaningful bulk to your kit. The optical formula runs 14 elements across 11 groups, pulling in one UD element to control chromatic aberration, one aspherical element to manage spherical distortion, and one large-diameter element to support the wide-angle design. Super Spectra coatings keep flare and ghosting in check, which matters when you're pointing toward bright windows or open sky.

The STM stepping motor is the right choice for video work. It focuses quietly and continuously, without the focus-hunting chatter that distracts in audio-sensitive recordings. Full-time manual focus override lets you nudge focus without switching modes. The 4-stop optical IS system handles the handheld shake that's inevitable when you're composing at 10mm without a tripod.

At this weight and price point in the APS-C wide-angle category, few lenses match what this one offers. The 22 cm minimum focusing distance and 107-degree angle of view at the wide end give you real creative flexibility that kit lenses simply don't provide.

Who It's For

Travel photographers carrying a single-bag kit get a genuine ultra-wide without the weight penalty of larger primes. Architecture and interior shooters benefit from the 107-degree angle of view and UD element combination that keeps straight lines cleaner across the frame. Videographers using EF-S Canon DSLRs will find the STM motor's near-silent focus indispensable for run-and-gun work or any scene with recorded audio. Landscape photographers shooting handheld in low light have a 4-stop IS system doing meaningful work when a tripod isn't practical.

FAQ

What's the equivalent focal length on a full-frame camera?

The 10-18mm lens gives you a 16-28.8mm equivalent field of view on APS-C sensors. That 10mm end delivers a 107-degree angle of view, which is genuinely wide without requiring specialty optics or awkward workarounds.

Is the autofocus fast enough for video?

The STM stepping motor was built for video work. It focuses continuously and quietly without the hunting noise that kills audio in recordings. You also get full-time manual focus override if you need to bump focus mid-shot.

How much image stabilization does it provide?

The optical IS system delivers 4 stops of shake correction. At 10mm handheld, that's the difference between sharp and soft when you can't or won't use a tripod.

What controls chromatic aberration in this design?

One UD (ultra-low dispersion) element specifically suppresses color fringing across the frame. Combined with the aspherical element handling spherical distortion, the optical formula keeps aberrations minimal across the zoom range.

How small is this lens really?

240 grams and 2.83 inches long. For an ultra-wide zoom, that's genuinely compact and won't unbalance lighter APS-C bodies or weigh down a travel kit.

What's the closest focusing distance?

22 cm (8.66 inches) minimum. That's close enough for environmental portraits and creative foreground separation without macro capability.

Can I use standard filters?

Yes, it takes 67mm filters. That's a common size, so you won't struggle finding ND or polarizing options if you need them.
