This cage is built for some serious impacts. It's made of thick aluminum alloy, with rubberized pads on the inside to provide even more protection.I love the orange metal buttons for the power and shutter. I have another cage that doesn't have them, and it's like fishing down a hole to find the buttons on that one. This cage keeps them easily accessible.The cage does not cover either of the two microphones and sound quality is not affected. The top of the cage has a cold shoe, and the right side has a 1/4"-20 female threaded hole for more mounting options.The battery access door is covered by the cage, but can be accessed simply by pushing the button on the back of the cage. The USB-C port door is not covered and is even easier to access.The camera slides into the cage easily, but once locked in, there is absolutely no movement at all. It fits very snugly.All that protection does come at a little cost, though, as it's not a lightweight cage. My kitchen scale weighed it in at 71 grams. You can definitely feel the weight difference. However, it does provide excellent protection, more mounting options, and a better grip for those 71 grams.Overall, an excellent accessory to protect your investment.
