Question 1

Is the Sigma 18-35mm f/1.8 discontinued?

Accepted Answer

Yes — Sigma has officially discontinued the 18-35mm f/1.8 DC HSM Art for Canon EF-S and Nikon F mounts. Versions for Sigma's own SA mount and some other mounts may differ in status. This makes the used market the main place to find one today, which also means prices have stabilised rather than continued to drop.

Question 2

Why is the Sigma 18-35mm cheaper than Canon's own lenses?

Accepted Answer

Third-party manufacturers like Sigma operate at a different price point than first-party Canon glass, partly because they serve multiple camera ecosystems and can spread development costs across many mounts. It doesn't mean worse quality — the Art series in particular is engineered to compete on optical performance, not just price.

Question 3

Does the Sigma 18-35mm f/1.8 work on Canon RF cameras?

Accepted Answer

The lens has a Canon EF-S mount, not RF. You can mount it on an RF-body using a Canon EF-EOS R adapter, but because it's an EF-S (APS-C) lens, the camera will crop to APS-C mode automatically on full-frame RF bodies. On an APS-C RF body with an adapter it works as intended, though native RF lenses will integrate more seamlessly.

Question 4

What's the 18-35mm focal range equivalent to on a Canon crop sensor?

Accepted Answer

On a Canon APS-C body (1.6x crop factor), 18mm becomes approximately 29mm and 35mm becomes approximately 56mm in full-frame terms. That's a useful walk-around range covering moderate wide-angle to a short portrait-length perspective — and all of it at f/1.8.

Question 5

Does the Sigma 18-35mm 1.8 have image stabilisation?

Accepted Answer

No, it doesn't have optical image stabilisation. For static subjects like landscapes or astro shots on a tripod that's a non-issue. For handheld video or low-light stills, you'll want to lean on any in-body stabilisation your Canon body offers, or keep your shutter speed appropriately fast.

Question 6

How does the Sigma 18-35mm f/1.8 compare to the Canon 17-55mm f/2.8?

Accepted Answer

The Canon 17-55mm f/2.8 gives you a wider zoom range and image stabilisation. The Sigma 18-35mm f/1.8 gives you a full stop more light and, according to many reviewers, sharper corners wide open. If you regularly shoot in dim environments or want smoother bokeh on a crop sensor, the Sigma's extra stop of aperture is a meaningful advantage. If you need IS and more reach, the Canon makes more sense.

Question 7

Is buying a used Sigma 18-35mm f/1.8 worth it?

Accepted Answer

For Canon EF-S DSLR shooters, absolutely. The lens is no longer in production, so second-hand is the way to get it. The Art series build quality means used copies typically hold up well. Just confirm autofocus is working properly and there's no internal haze — and make sure it comes with a warranty. On Camera-tweedehands.nl, every copy includes at minimum 12 months warranty.

Question 8

What Canon DSLR bodies work best with this lens?

Accepted Answer

Any Canon EF-S compatible body works — think the Canon EOS 90D, 80D, 77D, or the Rebel/Kiss series. The lens shines most on bodies with reliable phase-detect autofocus for fast subject tracking. Pair it with a body that has solid low-light AF performance and you'll make full use of the f/1.8 aperture in dim conditions.
