The DPS hood is a HASSELBLAD product . The number is 3072534 ,
Unfortunately this hood is not produced any more . It has a magnification of 5.5 and you can add a diopter according your eyesight (far distance) .
I got mine from RobertWhite in England . They might still have one , because the DPS hood is still in their product list .
Good prices , good service and fast shipping .

True enough , when disconnecting the CFV and then using a film back , you must not forget , then to use the whole screen . If you have used a DPS hood with your CFV back , then you also have to replace the hood and that makes it easier to remember .
For me , the DPS hood is a great help .
