This is a camera rig. I used it with a SONY A73. It's a very convenient rig for attaching a monitor, microphone, and light to a single-lens reflex camera. It's recommended for those who want to use their camera extensively as video equipment. Two pipes came out from the holes at the bottom, but I discarded them because I didn't use them. Although it's no longer available from NEEWER, similar models are still sold. According to their information, the compatibility is as follows: I used it with a SONY A73. Panasonic Lumix DMC-GH4, Sony A7, A7S, A7R, A7RII, A7SII In the third photo, there is a small scratch below the right pipe hole. There may be other minor scratches, but please consider this item with the understanding that it is used. - Brand: Neewer - Type: Camera Rig - Material: Aluminum - Color: Black/Red - Features: Adjustable Handle
