I have been looking for Quick Release holder to easily carry my OM-1 and other cameras. I have had an untitled cheaper version for some time, but will like to have a more thorough system that cover wider set of use cases: carring the camera, attaching to tripod and potentially other as well. The cheaper version was not extendable so I studied what was available and decided to go with PGYTECH. This far have nee satisfied. Let's see if summer arises new equipment needs.
