Ever since I moved to semi pro and pro level gear, I am talking about bodies and lenses that are "weather sealed" like all the Nikon pro bodies and lenses, I have wondered if the rubber seal around the mount really does anything? I mean dust still gets on the sensor,etc... It might keep most water out.
Then you have the AW1 (not a pro body) that is "water proof" to so many meters of water.
I mean is the weather seal on the mount for pro grear really just smoke and mirrors or does it really work.......?
