I've been looking for a chimney finder or something similar for my Mamiya RB67 ProS and was fortunate to find a used Mamiya RB67 PD Magnifying Hood at a very good price at Kenmore Cameras.
This is the version with a silicon cell (not a CDS one) - it takes a PX28 battery and is referred to on the attached accessory chart.
Does anyone here have a manual scanned? Mike Butkus' site only seems to have one for the older CDS version.
Alternatively, can someone walk me through what the significance is of/how to work with the coloured LEDs in the finder (I know that Green means correct exposure).
Also, if anyone has any other suggestions about how best to use it, they would be appreciated.
