Question 1

What is the difference between the Sigma 24-70mm f/2.8 EX DG HSM and the Sigma Art 24-70mm f/2.8?

Accepted Answer

The EX DG HSM is a DSLR-era lens designed for Canon EF (and other DSLR) mounts with a traditional optical formula. The Sigma Art 24-70mm f/2.8 DG DN is a mirrorless-native design built for L-mount and Sony E-mount systems — it is not available in Canon EF mount. If you're shooting on a Canon EF-mount DSLR body, the EX DG HSM is the Sigma option that actually fits your camera. The Art version is optically more modern, but it physically cannot be mounted on EF cameras without an adapter.

Question 2

Does the Sigma 24-70mm f/2.8 EX DG HSM work on Canon crop sensor (APS-C) bodies?

Accepted Answer

Yes — because this is a full-frame lens on a Canon EF mount, it covers the image circle of any Canon EF-mount body, including APS-C DSLRs like the Canon EOS 90D or EOS 7D series. On an APS-C body, the 1.6x crop factor means you're effectively working with a roughly 38–112mm equivalent field of view, which is actually a useful portrait-to-short-tele range. Autofocus and exposure control work normally.

Question 3

Is the Sigma 24-70 2.8 EX DG HSM good for weddings and events?

Accepted Answer

It's a solid choice. The constant f/2.8 aperture handles low-light reception halls and dim churches without forcing you to push ISO through the roof. The HSM motor focuses near-silently, which matters during ceremonies where noise is unwelcome. The 24–70mm range covers group shots at the wide end and flattering portrait compression at 70mm — so you can work an entire reception with just this one lens if needed. The lack of image stabilisation means you'll want to keep your shutter speed up in low light, or rely on in-body stabilisation if your camera body offers it.

Question 4

Does the Sigma 24-70mm f/2.8 EX DG HSM have image stabilisation?

Accepted Answer

No — this lens does not include optical image stabilisation. For handheld shooting in lower light, the rule of thumb is to keep your shutter speed at or above 1/focal length (so at least 1/70s at 70mm). If your Canon body has in-body stabilisation (IBIS), that will compensate. Alternatively, shooting at f/2.8 gives you enough light-gathering ability to use faster shutter speeds compared to slower kit zooms.

Question 5

Is buying a used Sigma 24-70mm f/2.8 EX DG HSM worth it?

Accepted Answer

For Canon EF DSLR shooters, a used copy of this lens offers a constant-aperture standard zoom at a fraction of the cost of buying new. The lens is built with a metal barrel that holds up well over time, and the HSM autofocus system is reliable. At Camera-tweedehands.nl, every used lens is individually inspected and comes with a minimum 12 months warranty. We document the condition grade and any findings in the inspection report, so you know exactly what you're purchasing.

Question 6

What filter size does the Sigma 24-70mm f/2.8 EX DG HSM use?

Accepted Answer

The filter thread is 82 mm.
