No, this is a handheld accessory. You hold it in front of the lens, which allows you to dynamically move the effect and adjust the angle during the shot.
It performs best on lenses 35mm or longer. On very wide lenses (under 24mm), the edges of the prism may become too defined in the frame.
The glass is water-resistant and can be used in light rain, but it should be wiped dry immediately with a microfiber cloth to prevent water spots.
