I keep reading mixed messages abouit the waterproofness of Zeiss Dialyt 10x40b's (1988). I've been using these , well since 1988, but I am hesitant to take them on tropical forest expeditions and take some Pentax DFC SP's instead (these have always been fine until stolen!). What do people think about taking Zeiss into testing tropical conditions?
