The MkII version of the flagship Canon Speedlite features a host of improvements including a metal hot shoe with an improved locking mechanism for added durability, an external metering sensor for non-TTL automatic flash exposure control and a PC socket for use with non-dedicated slave triggers. Being fully compatible with all EOS SLRs, the Speedlite 580EX MkII is gasketed for dust and moisture resistance, making it possible for users of EOS-1 class digital SLRs and many L-series EF lenses to use flash safely when shooting in dusty or wet environments.
