I never understood what the use of camera frames was all about. UNTIL I started learning how to make videos. I started using my cameras for photography only, but I'm slowly transitioning to video as most clients are starting to be interested in videos as well as images. Therefore, when I bought additional accessories, I noticed that all these accessories do not fit my camera because it only has one hot shoe. This also includes small rigs. The more I researched, the more I discovered that video and film makers swear by this product. So many accessories can be attached to them - monitors, extra batteries, flashes, storage, pens. The thing does everything. and it looks well made and durable. I am very satisfied with this product. I found it a bit pricey but if you want the best sometimes you have to pay for it. There are two points of contact - the bottom screw and an extra Allen key and the screw you attach the upper right metal strap holder to. Cell.
