You have to admit that you would like to know if the first Sony SLR camera supposed to be a pro photo camera, the Sony Alpha 900, is really up to the real-life constraints of a pro camera. Some people would really test it: Michael Reichmann from Luminous Landscape, simply took a Sony Alpha 900, a Sony 70-300mm f/4.5-5.6 G tele-zoom and 5 other lenses, for two weeks of photo travel in the Southernmost countries of this world. Result: A rather positive opinion, no real issue after submitting the photo camera to low temperatures and high humidity that were out of its normal operating range.
He also noted the incidents other cameras suffered around him (no less than 77 other photographers!). For example, the Canon EOS 5D MkII which did not survive in cold rain.
