Old Man’s Vertical Holds

I’m still trying various ways for an old man with arthritic thumbs to hold an Olympus E-M5 III camera vertically.  I need to be able to operate the camera while putting minimal pressure on my thumb root joints.  These are a few examples that I am trying while using different eyes as well as either the EVF or the LCD to compose.

I made the images using the 75mm lens at an aperture of F1.8 or 2 on the E-M5 III camera.
