I got a couple of these prior to a trip to England and Norway, as the weather forecast did not look favorable. Fortunately, I only needed them on one day, but when I did need them they worked great! Paired up with a lens hood, my camera stayed dry. It was easy to operate all the controls, and they didn’t get in the way of the eyepiece at all. Going to make sure I keep at least one of these in my bag all the time!
