I purchased this for my Panasonic GH5 and when I mount it to the camera it clicks in place, but there is still slight movement. It doesnt lock in tight. When I use a zoom lens for video it moves and effects the image.I have tried it on 2 bodies and both are the same. Does anyone else have this problem?

As an Olympus user, i have used this adapter on both my EM1-2 & EM1-3, with several different lenses; nothing longer than the Canon 180 macro. I have never had an issue as described in the question
