I got an Olympus Varimagni angle finder (the old OM system one, from the 70ies) to take measurements. I designed an adapter to mount it on the E-M1 family cameras.
Here you see the Olympus Varimagni (left) and the Olympus VA-1 (right), both with E-M1 family adapters.
More about the adapters on my Angle Finder page.
After a series of tests I have built a BLH-1 battery dummy for Olympus cameras (currently the OM-D E-M1 Mark II). Since the battery is larger than other models, the lid of the battery compartment is also bigger. This allows to cut a slot for the cable to pass through while the lid is closed. You shouldn’t do this to the original lid. That’s why I currently try to get spare battery compartment lids for the camera.
You may find more details about battery dummies on my Battery Dummy Page.
Olympus presented the new µFT camera flagship as a prototype. Technical details are very promising. First reviewers pointed out, that the missing accessory port doesn’t allow to use teh electronic swivel viewfinders.
There is a solution to this problem. The receptacle for teh eyepiece is very similar to the one of the predecessor. That means, that my angle finder adapter I built for the E-M1 will also fit the E-M1 II. Therefore, the optical viewfinder VA-1 can ve used with the coming camera!
