In reply to Dispater: 5D III has same AF module as 1D X, just lacks the second AF sensor and processor. 5D III sensor is incredible, heaps better than a 1Ds III. 5D's weather sealing is specced the grade below a 1D XYZ but the grade above a Mk II (straight from Canon, not opinion) ISO performance of 5D Mk III is pretty great but weirdly the EOS 6D has been proven better for ultra high ISO use, astrophotographers are now all switching to 6D's, shame the build quality is absolute carp.
Water damage is a pretty cruel mistress but a carrier bag with an elastic band is a perfect rain coat
