[QUOTE="pforsell, post: 522188, member: 7240"] Weather sealing means rubber O-rings at the holes for the buttons and such to prevent water from seeping in. I don't think those openings to the body are useful for cooling even without rubber seals. Non-sealed cameras are pretty much tight enough to keep moisture and dust out, and don't blow hot air out of the button holes either. The only meaningful way to cool the camera internals is via convection, not via airflow through button holes. Metal body is good for transferring heat from the hot electronics to the metal shell, but then again it is held in a warm hand. In some Olympus (maybe Evolt E-5 ?) camera there was a small blower fan inside the camera body, but without external holes. The blower just redistributed the generated heat from one part of the camera to other parts to help the dissipation to the environment. The downside is that the E-5 was not silent. [/QUOTE]
