Uses to explore
What works well
- 100–400mm lets you reframe without changing lenses.
- Optical stabilization helps reduce camera shake when handholding still subjects.
The tradeoffs
- The maximum aperture narrows to f/8 as you zoom in; moving subjects in dim light are harder to freeze.

Will it fit my camera?
Fits both full-frame and APS-C Canon EOS R cameras directly. On APS-C, the view is narrower: multiply the focal length by 1.6 for the full-frame equivalent angle of view.
Not for Canon EF, EF-M or DSLR camera bodies.
