Auto Extension Tubes

The Mamiya extension tubes are precision machined for close up and macrophotography. They are fully meter coupled for automatic or manual exposure. The two automatic tubes can be used individually or in a combination.

No 1 = 45mm extension

No 2 = 82mm extension

No 1 + 2 = 127mm extension

Since the camera body bellows features an extension of 46mm, using the tubes provides a total maximum extension of 173mm.

No 1 is for the RB SD, RB PRO-S and RB Pro cameras: JP Code 944069 Mamiya Code Y21711.

No 2 is for the RB SD, RB PRO-S and RB Pro camera only: JP Code 944071 Mamiya Code Y21712.
