Really stupid question of the day.
After a recent trip to the Keys, I've discovered snorkeling. I bought one of those plastic 35mm point & shoot underwater cameras and I was amazed how good a couple shots turned out with such a crappy camera. Now I'm hooked.
Underwater housings for digital and other cameras are quite expensive, so right now there are used 35mm underwater systems that can be had very reasonably. But before I plunge (litterally and figuratively) here's the dumb question:
Is there such a thing as an underwater 4x5 system of any kind?
