It’s hard to find an Olympus VA-1 angle finder. Therefore, I did some research to find an alternative. The Seagull universal angle finder hits the bill. It is available, reasonable priced and it got a mount for adaptors. In addition to the large number of adapters that are already shipped with the angle finder, I developped three more.
One for the OM-D E-M1 and E-M1 II, another one for the three cameras OM-D E-M5 II, E-M10 II and E-M10 III and a third one for the PEN-F.
