We do quite a bit of shore diving in Cold Water (drysuits, double steel tanks) with my 25 lbs. Camera.
I enter the water along with my buddy, carrying my fins and camera. I hand the camera to my buddy to hold while I put on my fins, then I put thier fins on for them (since they are being nice and holding my beast) , then get my camera back. This works very well for me as long as the waves aren't huge.
I often reverse this process when getting back up into my dive boat. Hand the camera to a buddy, take my fins off, climb the ladder, drop my gear, pick up the camera, then pull my ever so helpful buddie's fins off for them.
