Baierfoto adapter for using Hasselblad prisms on a Rolleiflex with removable finders. This product is of the highest quality machined in Germany even the black color matches a Rollei. The photo is the adapter mounted on an 3.5E3.
Wasn’t the PME made for the Acute Matte non-D screen? If it doesn’t auto compensate then it still would be a simple matter to manual calibrate with an external meter and adjust +/- ev.
I have one of these. As Rayt says, it's a very high quality product, and it does expand what you can do with your Rollei. I once thought I'd lost mine in a move, and went looking for another, and couldn't find one, so IMHO it's a relatively rare device. GLWS.
The Hasselblad PME is calibrated for an Acute Matte out of the box, but can be recalibrated for (Hasselblad) standard screens, or you can just compensate using the ISO setting. As I recall, the manual has adjusted ISO settings for use with a standard screen.
Probably not exact for use on a Rollei, but would get you in the ballpark, most likely.
A Rollei with a Maxwell screen is identical to an acute matte d screen. I had both but never the PME prism. I do have the unmetered prism with the baierfoto adapter and it’s a beauty! Perfect to use if you use or need the cold shoe a lot
