Here is how I plan to hold the camera!
The display screen doesn't cover the entire back of the camera. Glass extends across the back, but there is a display-less border on the left. I can put the bottom of the camera in the crook of my thumb and my thumb itself along this border.

In the picture above is what I call a finger lanyard. There are two knots tied in the gold colored twine. The first knot makes a loop for my finger and the second knot makes a good place for my fingers to pinch while I inset my middle finger in the loop.

With my middle finger in the loop, my forefinger and thumb are free to do whatever is needed. I can hold the camera pointed down with middle finger under the body and the finger lanyard keeps it in place. If the camera slips off the finger, it won't fall because the finger lanyard is snug enough I have slide my finger out anyway.

This has all worked great for point/shoot cameras; they don't weigh much. I think it will work fine for me using the E-PL6 with small lenses. I rarely use the finger lanyard but it is there if I need it. The lanyard is suitable for me because I don't use neck straps and things for cameras.
- - - The thing that is awkward here is putting my finger through the loop. I pinch the second knot (mostly area between the two knots + knot itself) between my left hand forefinger and thumb and slip my right hand middle finger in. The weight of the camera makes this a delicate operation so it doesn't slip. I mention this because care is needed to not pull the camera from the left hand slipping the right finger in. So, maybe this isn't for everyone :^)
