b) All those torture tests are rubbish. Consider so-called weather-sealed cameras such as Canon 1Ds3 and Nikon D3. Read what a REAL user has to say here:
"The Canon 1DsIII, in spite of weather sealing, has often had fogging inside the LCD screens; even worse, after one week the exposure meter has gone crazy, underexposing all the photos by about 2-3 stops....
My friend Simone has not had better luck: his Nikon D3 developed various problem, and three lenses got stuck and heavily fogged...
From now I'll no longer thrust the weather sealing - I'll simply protect the camera with a transparent plastic bag, that is light years better than any weather sealing."
1. the hot tea test, canon still works while the nikon just got jam
2. not a fair test with those nails, the angle and the strength used when using the lens to hammer and if u compare both, nikon takes a more serious damage despite the lens on canon broke. I even heard him in self denial mode saying this is not meant to be for nikon.
my views, stupid test he is doing cos no one will use their cam to hammer nails (although its trying to imitate rough usage, but nails? oh comeon...), and no one will walk on their cam all over the streets.
