Vivitar A35 lens mount_Olympus OM long exposure controlThe Vivitar A35 is "Splash Proof" but, and you will know this when you hold the camera in your own hands, you should take that with a huge grain of salt. There are gaskets on the battery compartment and the film door, a membrane over the shutter button, and a glass window over the lens, so it's not nothing, but the extent to which those are effective is unclear. Anyway, keep it as dry as you can. Runs on two AA batteries (included.)
