That it is only guaranteed to work with some Canon lens).
Of course - as you have shown - it does not mean it will NOT work.Canon engineers have specified that only the lenses listed below are officially compatible with the focus bracketing feature. However, reports exist of additional lenses appearing to be supported by this feature. While it seems safe to say that all RF lenses will be supported, that expectation has not been confirmed by Canon. We also do not know why official compatibility is limited to this list of lenses, though the lenses on this list seem like logical choices for use with this feature. "We absolutely cannot guarantee proper Focus Bracketing operation when third-party lenses are attached."
Canon RF 24-105mm f/4L IS USM Lens
Canon RF 28-70mm f/2L USM Lens
Canon RF 35mm f/1.8mm f/1.8 IS STM Macro Lens
Canon RF 50mm f/1.2L USM Lens
Canon EF 16-35mm f/4L IS USM Lens
Canon EF 24-70mm f/4L IS USM Lens
Canon RF 35mm f/1.8 IS STM Macro Lens
Canon EF-S 60mm f/2.8 Macro USM Lens
Canon EF 100mm f/2.8L IS USM Macro Lens
