Best low-light lenses for the Canon EOS R10

Canon EOS R10 · 2022 · 24.2 MP APS-C · 426 g · no IBIS — stabilisation is lens-only

17 low-light lenses that fit the Canon EOS R10 (Canon RF mount) — fast apertures (f/1.8 and brighter) for dim conditions. Sorted brightest-aperture first; every spec from the manufacturer's catalog.

Start with the Canon RF 45mm f/1.2 STM. At f/1.2 it is the brightest of the 17 low-light Canon RF lenses that fit the Canon EOS R10 — the full comparison is below.

It is a full-frame lens. It fits and shoots at full resolution, and the glass often carries over if you move to a full-frame body later — but for the same framing it is larger, heavier and dearer than a lens built for this sensor. The brightest APS-C option here is Sigma 16mm f/1.4 DC DN Contemporary at f/1.4.

One limit of this table: it lists only Canon RF lenses that mount natively on the Canon EOS R10 — lenses fitted through an adapter are not included here. See which mounts adapt to which.

What these focal lengths actually give you on the Canon EOS R10

The Canon EOS R10 has an APS-C sensor, so it sees a 1.6× crop of what each lens projects (Canon's APS-C is 1.6×, not the 1.5× used by Sony, Nikon and Fujifilm). Every focal length below therefore frames 1.6× tighter than its marked number. A 50mm on the Canon EOS R10 frames like 80mm, not the "normal" view its marked number implies.

Effective focal lengths are the marked focal length × the 1.6× sensor crop factor — the field of view, not a change in the lens itself. Aperture and depth of field are unaffected.
