Hello, I am a newbie Scuba diver and love the idea of underwater photography! That being said I know very little about it and am hoping some of the experienced underwater photographers will chime in here and give me some advise. First, can a Canon 60D be used underwater? I realize it's now considered an older model camera, but I have one lying around in "perfect condition" and am wondering can it be refurbished to use under water? If so, what housing would you recommend? Also what lens? I am finding the simple point and shoot camera fun to use underwater but they just don't measure up the versatility of a SLR. Your assistance is greatly appreciated! Thank you.
