>Is the set below correct? Does it works auto-diaphragm with a AR-7? >FM2 + BR-2A + Reversed Lens + BR-6 + BR-3 + Filter No. You don't need a BR-3 if you are already using a BR-6. But the BR-6 does give you auto-diaphragm with AR-7. When you press the AR-7 the diaphragm is stop-down first and then the shutter release is pressed. /Isaac
