Canon 24-105mm f/3.5-5.6 IS STM EF-Mount Lens {77}

Canon's 24-105mm workhorse covering wide to short telephoto.

The Canon EF 24-105mm f/3.5-5.6 IS STM gives you a focal range that handles most shooting situations without a bag change. At 24mm you have enough width for interiors and environmental portraits, and 105mm pulls in enough compression for tighter headshots or distant subjects. The STM motor runs quietly, which matters the moment you start rolling video on a Canon DSLR. Image stabilization adds a meaningful safety margin when light drops and you need to hand-hold at the longer end.

The 77mm filter thread is the standard diameter across a wide range of Canon L-glass, so if you already own 77mm filters, they transfer directly. Native to Canon EOS Digital and EOS Film bodies, this lens also adapts to Sony E, Canon RF, Nikon Z, Fuji X, and L-Mount systems with appropriate adapters, which means it travels well with shooters who work across platforms. That adaptability keeps this lens relevant long past any single-body upgrade cycle.

Who It's For

Travel photographers working from a single bag will appreciate the 24-105mm range covering wide establishing shots through compressed detail work. Video shooters on Canon DSLRs benefit from the STM's near-silent focus pulls during live recording. Documentary and event photographers who move between environmental context shots at 24mm and tighter subject isolation at 105mm can stay on one lens across a full shoot. Photographers already invested in 77mm filters get direct compatibility without additional step rings or adapters.

FAQ

What's the autofocus behavior on this lens for video work?

The STM (Stepping Motor) design enables smooth, nearly silent focusing during video capture, which is why Canon built it into this lens specifically for DSLR movie shooting. You won't get the instant snapping that older AF motors produce.

Does this lens work on mirrorless systems?

Yes, with an EF-to-E mount, RF mount, Z mount, X mount, or L-Mount adapter. The optical performance stays unchanged, though you lose Canon's native AF speed and gain the weight of an adapter ring.

What's the actual aperture range across the focal length?

f/3.5 at 24mm and f/5.6 at 105mm. The aperture narrows as you extend to the long end, which is typical for this class of zoom and something to factor in when you're shooting telephoto in dim light.

Is image stabilization effective at 105mm handheld?

Yes, the IS system gives you roughly 3-4 stops of compensation, which means you can shoot somewhere around 1/30th without camera shake at the tele end. That margin matters when you're working indoors or in overcast conditions.

Can I use my existing 77mm filters on this lens?

Directly, yes. The 77mm thread matches most of Canon's L-glass lineup, so your CPLs, NDs, and UV filters swap straight across.

How does the 24-105mm range compare to a standard 18-55mm kit lens?

You gain 6mm on the wide end and an extra 50mm at the long end, which shifts the lens toward actual telephoto work instead of wide-to-normal coverage. The wider maximum aperture at the short end helps too.

What bodies does this mount to natively?

Canon EOS DSLR bodies with EF mounts, both digital and film bodies from the EOS line. It won't fit EOS M, RF, or any non-Canon mount without an adapter.
