Questions our customers asked
Will this lens fit my Canon R5, R6 or R8 (full-frame)?
It mounts, but it's an APS-C lens — full-frame RF bodies auto-crop to about 1.6x when they detect it, cutting resolution (roughly 8-9MP on a 20-24MP body). For full resolution, use it on Canon's APS-C RF bodies: EOS R7, R10, R50, R100.
What comes in the box?
Lens with front and rear caps and a lens hood (exact in-box list not published for the Canon RF SKU — this matches the standard Sigma Contemporary packaging on every other lens in this line).
What's special about the constant F2.8?
Most ultra-wide zooms this small vary their aperture across the range (e.g. F3.5-6.3). This one holds F2.8 from 10mm to 18mm, at just 270g — Sigma calls it the world's smallest and lightest F2.8 zoom for APS-C.
The world's smallest and lightest F2.8 zoom for APS-C mirrorless — a constant-aperture ultra-wide that fits in a jacket pocket.
An ultra-wide zoom for landscapes, interiors, vlogging and architecture, with one aperture that stays F2.8 across the entire zoom range.

Mount note: This is an APS-C-only lens (Sigma's "DC" / "DC DN" line), not a full-frame lens. It physically mounts on any Canon RF body, but it's built for the smaller APS-C sensor — Canon's full-frame RF bodies (EOS R5, R6, R8, R3, R1 and similar) automatically switch to a roughly 1.6x cropped mode when they detect it, cutting resolution hard (about 8-9MP on a 20-24MP full-frame body). For full-resolution results, use it on Canon's APS-C RF bodies: EOS R7, R10, R50, R100 and similar.
