Mamiya UK Forum: General: What is the difference between "auto extension tube" and simple "extension tube"

Username,

I am only aware of Mamiya producing one type of extension tube set for the RB and I would class this type as auto, as it charges/discharges the shutter and diaphragm. I suspect the vendor has omitted "auto". Please get them to clarify.

Does anybody can explain me what is the difference between "auto extension tube" and simple "extension tube" for Mamiya RB?

I have Mamiya RB ProS. Which one will match it?

Thanks.
