Taking the Canon M5 underwater or not.. in Photography Gear and Technique Posted August 24, 2020 Thanks for the reply. The biggest disadvantage of any of the systems is indeed the battery. When shooting the SLR you could easily go multiple days without needing to recharge the camera. The investing I did now into the Sea&Sea house are pretty limited. So I'm not stuck on staying at Sea&Sea The ports are not that often coming on the second hand market and they are pretty expensive. The Nauticam houses have some really nice features with the build in leak/vacuum sensors and the versatility in all available ports and rings.I'll look a bit more into the EM range to see what would suit me best. And further for specific features im looking for. It should be to bulky to be carrying around. Allot of the times when taking along the camera on dives there's hardly anything to shoot and the camera just hangs on system.
