The Optech Rainsleeve Flash camera rain cover is a shaped plastic bag with a drawstring fitting around the lens and a viewing hole for the eyepiece. It also has an extension to allow a flash to be attached and protected. The design allows all the camera controls to be operated whilst providing good protection from a sudden downpour. It holds any size of DSLR body and a lens up to 70-300mm size (35.6cm long, so shorter than the standard version). Pack of 2, ideal to keep in a bag for emergency use.
