Still, there shouldn't have been any problems. Any reasonably well-made lens mount should be waterproof. I've had water on the eyepieces of a great number of different binoculars and several scopes, and I never had any problem with water getting inside the eyepieces at all.The weak spot of porros usually isn't the lens mounts, it's the focussing. Once you get some water in the gap between the eyepieces and the body it's almost inevitably drawn into the body as soon as you focus the binoculars, especially when you focus from infinity to the near point. Some of the old Zeiss West porros had  special rubber seals fitted between the eyepieces and the body to prevent that from happening. These bins were virtually waterproof - as long as the seals weren't worn out. I personally would be pretty careful with virtually all the traditional porros, including the Nikon SEs. In really wet conditions I much prefer fully sealed roofs or indeed porros with individual eyepiece focussing like the Zeiss 7x50 Classic. I wouldn't really want to use my SEs in driving rain or for seawatching at the coast.</blockquote>
