Upload & Sell: Off
Indeed, high dynamic range is not all. But, I do not think it is the beginning of the end of the DSLR. One might as easily say that it is the end of the point&shoot camera because that market wants convenience and seems to say "why carry two cameras: a P&S and a good camera phone?".
In July, after the 5D Mark III was announced and shipped for a little while, there was much hand-wringing and gnashing of teeth and wailing at the price, usually about $3500 at the time. Some people believed that Canon had made a huge mistake and thought the camera was not selling well and believed the Nikon D800 was selling like hotcakes. They predicted that the 5D3 price would be below $2700 by Christmas.
Well, here we are, in the middle of a big sale on the D800 by Nikon, and we can take a reading using B&H as the benchmark. Their price on the D800 is $2800, which includes a $200 instant rebate from Nikon to try to get sales moving and includes a shoulder bag, 32 GB card, and spare battery from B&H to try to get sales moving.
By contrast for Canon, the predicted price for the 5D3 was to be $2700 or lower by now, well south of $3000, but instead it is $3150 at B&H. That is not the nominal price because retailers are restricted from advertising their actual selling price. (Note that the nominal price is $3500 which is what is on Canon's site too.)
In any price thread like this, there will inevitably be posts about various shades of retailers offering lower prices and about kits that people can spend time breaking up and trying to sell lenses separately but, for benchmarking, the B&H camera body price is well established.
As a final observation, it seems that those who were so sure Canon had made a suicidal mistake and that the 5D3 would die in the marketplace, in competition with Nikon D800 and its other offerings, have been proven wrong.
