Extension tubes for RF lenses

[DaveHughes]

Hello, 

I am looking for an extension tube for the RF system. I have the Extension Tube EF 25 II for the EF system that I use on a regular basis. As far as I know Canon does not offer one for the RF system at the present time.

I am not aware of any extension tubes for the RF mount, either.  If Canon has not released a set, then the only third party brand I would trust is Vello.  Don’t hold your breathe, though.  I would not expect to see them until Canon releases RF mount bodies with more entry level price points.

I've found a few online but most have complaints about quality and tightness of fit. I really hope Canon does come out with extension tubes for the RF mount.
