If you can't recover highlights, who cares if you have two extra FPS and built in GPS with Insta-Facebook upload?
If you are shooting at ISO 3200, does the D4 still have better DR?
If your autofocus gives you a blurry image, who cares if you have an extra stop or two of dynamic range?
If the autofocus gives you a blurry image, isn't that the fault of the shooter? Or was there some other problem that explained why Rob Gilbraith was reporting lots of issues with the Canon 1D3 AF that Canon never seemed to be able to fix?
If you miss a key moment because your frame rate was too slow, who cares if you can't recover a blown highlight?
So it is a good thing that they keep working on those JPEG algorithms, yeah?
If you need a 17mm TS/PC lens, or a hand-holdable 600mm f/4 lens, how useful is a sensor with better low ISO DR?
For some reason, everyone that I've seen shooting with a 500mm or 600mm lens has it mounted on a monopod or tripod. Could it be because they actually use it for work and shoot with it for more than a few minutes each day and don't have the time to become Mr Universe in order to work without a support?
