This rain shield goes on easily, it protects the camera and lens from rain. and is a much better option than the rain sleeve I've been using as it is easy to access the controls. It works great when shooting using a horizontal format. Shooting a vertical isn't as easy as I would like. It would probably work well if you use a pan and tilt tripod head but I use an L-bracket on my camera combined with a ball head. You can't just flip your camera over from a horizontal format to a vertical format that the L-bracket was designed to do.

I like to photograph waterfalls and I would like to see an opening that makes it easy to switch from horizontal to vertical.

Advantages: Good protection, easy to use.

Disadvantages: Hard to switch from horizontal to vertical format when using an L-bracket and tripod.
