The Op/Tech USA RAINSLEEVE- FLASH (Pack of 2) (Clear) is designed to protect a camera, lens and shoe-mounted flash from any unexpected weather conditions. There is an eyepiece opening that will fit most camera viewfinders that allows composing shots through the lens, not through the plastic. The camera and lens controls are easily visible and operable through the rain sleeve with an extra area to protect the flash unit. A drawstring lens opening provides easy access and a snug fit for the sleeve. It will fit an SLR camera and lens up to 14″ with a 7.0″ lens diameter.
