Sigma 24-105mm f/4 DG OS (HSM) A (Art) Lens for Canon EF-Mount, Black {82}

Sigma's Art-grade 24-105mm f/4 with full-frame OS for Canon EF

The 24-105mm focal range covers wide environmental shots at 24mm through short telephoto compression at 105mm, making this a single-lens solution for shooting days when swapping glass isn't practical. The constant f/4 aperture holds steady across the entire zoom range, so exposure doesn't shift as you reframe. Optical Stabilization compensates for camera shake during handheld work, and the Hyper Sonic Motor delivers quiet, fast autofocus that won't disrupt subjects or draw attention on set.

Sigma built this under their Art line, which signals a priority on optical performance over size or weight savings. The 82mm filter thread is larger than typical kit lenses in this range, reflecting the glass elements required to maintain edge-to-edge correction at full-frame coverage. Canon EF mount means native compatibility with the full EOS Digital and EOS Film ecosystem, and with adapters, it crosses to Sony E, Canon RF, Nikon Z, Fuji X, and L-Mount bodies. That adapter flexibility makes this lens a long-term investment regardless of where your camera system goes.

Who It's For

Wedding photographers working reception halls and outdoor ceremonies will find the 24-105mm range handles both the wide group shots and tighter portrait moments without a lens change. Documentary and editorial shooters benefit from the OS system during available-light handheld work, where camera shake is a constant variable. Travel photographers who want Art-line optical quality without carrying a second zoom will find the 24mm wide end and 105mm reach covers most situations. Canon EOS film shooters running this on a 1V or EOS-3 get full mechanical and electronic compatibility with no compromises.

FAQ

Does the f/4 aperture stay constant across the entire 24-105mm zoom range?

Yes. The constant f/4 maximum aperture holds from 24mm through 105mm, so you won't lose light or need to adjust exposure as you zoom.

What does the OS (Optical Stabilization) do, and how many stops of correction does it provide?

OS compensates for camera shake during handheld shooting. Sigma doesn't publish a specific stop count for this model, but stabilization is most effective in the telephoto range where shake becomes noticeable.

Is autofocus fast and quiet for video or live subjects?

The Hyper Sonic Motor (HSM) delivers fast, nearly silent autofocus. It won't disrupt sound recording or draw attention on set, making it suitable for both stills and video work.

What's the filter thread size, and why is it 82mm?

The filter thread is 82mm. That's larger than typical kit lenses in this range because the Art line prioritizes optical performance across the full-frame image circle, requiring more corrective glass elements.

Will this lens work on other camera mounts with an adapter?

The EF mount version works natively on Canon EOS bodies. With third-party adapters, it can cross to Sony E, Canon RF, Nikon Z, Fuji X, and L-Mount systems, though autofocus compatibility varies by adapter quality.

What's the difference between the Art line and Sigma's other lens lines?

The Art line prioritizes optical correction and sharpness over compact size and weight. Expect larger glass elements and a bigger physical footprint in exchange for edge-to-edge performance on full-frame sensors.

Can I use this on crop-sensor Canon bodies?

Yes. The DG designation means full-frame coverage, so it works on APS-C bodies like the 90D or M50, though you'll get the telephoto compression of approximately 38-168mm in crop terms.
