The two supplied Rain Covers are is to to use one with and the second without flash. I have on Canon 5D Mark III, 24-70mm lens and Speedlite 580EXII the first hood trying raise which unfortunately did not work out, I had to first remove the Blitzgäret and to put an end to some trouble under the hood back on the camera, the second without Blitzgäret goes well but is a bit tight. Dar the entire camera is covered by the film, the object is still clearly visible through the viewfinder, it is only meant to be an emergency, I'll say. Delivery soon.
