RF 100-500mm Manual Focusing with AF Engaged

[DEC]

When using the RF 100-500mm lens (attached to a R5), and the lens switch is in the AF position, can you also use the manual focusing ring to override the auto-focusing?  The focusing ring does have any effect when the lens is switched to AF.  When using my older EF 100-400mm lens, I can use the focus ring to override the auto-focus.  Is this function not available on the RF 100-500mm lens?  Or, am I not doing something or is the lens defective?

You should be able to use the focusing ring while the AF switch is set.  The lens uses dual Nano-STM motors that are not connected to a gear mechanism, so there is no issue.

Spoke to Canon's tech support and found out that on the R5 camera, in the AF menu, the "Electronic full-time MF" has to be enabled.  Which was not enabled on my camera.  Problem quickly solved!

Ah, I thought you had done that already and was asking if this would cause an issue.  Glad you got that sorted.
