I'm looking for a digital camera to take with me on deployment. It needs to be simple, pocket-sized, and water/dust-proofing is a definite plus. I bought a Pentax Optio WPi that I like everything about except for the night-time feature. To take pics at night with this thing you pretty much have to hold the damn thing as still as possible for as long as possible. I've seen cameras that had an infra-red mode that took pictures and videos in shades of green. I would love to find a camera that combined the water/dust proofing, pocket size, and ease of use of the Optio with the shades of green infra-red capability. Does such a thing exist?
