Someone emailed me about a way to use a Camera strap without the Tripod mounting hole, but something that can be taken off easily. Here's something I used to do back when I was flying the Steadicam Merlin stabilizer. I used the strap to carry the camera, but then needed a way to quickly take it off when flying. The shifting weight of a Camera strap can totally throw a stabilizer off balance.
Here's a simple DIY way to add a very comfortable strap to your camera. Just add a few small keyrings (don't look at my example, it's all I had right now) to the OEM strap holders. After that you'll be able to add laptop bag straps or luggage straps with swiveling ends. On quick, and off quick. One cool looking comfortable strap I found would be the Air Cell one via Amazon.
