The body is not designed to attach a shoulder strap. It only has the small opening for a hand strap. A good question. It would be a nice option to have on future models. As I mentioned in my review, a good belt pouch works well with this camera.
No, only a place for a hand strap on one side. I found that it was convenient to put it in a jacket pocket. A small pouch is good too. It may be on account of its light weight they didn't have a strap option.
