This camera rain cover is a decent idea, but has a few constraints. The cover is large enough to fit my Panasonic Lumix S5 MII XCE without problem, and thanks to the large zip fastening can even accommodate my camera when it's in a Smallrig Black Mamba cage kit (complete with top handle) - although this restricts the lens options, since it pulls the fabric tighter around the camera, and misaligns the camera back from the viewfinder opening. There is a long ‘sleeve’ type arrangement to go around the lens which includes a sticky feeling silicone strip and hook and loop tape fastener to help keep things snug.

There are arm openings at either end, with drawstrings around them to tighten and help prevent rain ingress. It's easy to tighten one of these, but the second is less so. A tripod can easily be connected at the bottom. The back is made from a clear plastic fabric, which allows visibility, but does get wet. So you can see the camera’s controls and use the screen whilst it's in this cover, though it’s not so easy when raining heavily

Does a good job of keeping rain off the camera and retaining full functionality whilst not obscuring the lens. The cover is lightweight and folds down to a fairly small size for storage - the black fabric folding easily whilst the clear elements are stiffer.
