No thanks... Almost as heavy as my D700 with none of the advantages
This is only 27 g less than the body of my D700, though it misses the full frame sensor, lenses beyond their lens' range in both focal length and speed, specialty lenses and more. If you want something akin to this with less weight, I'd suggest you go for a four-thirds camera or even a micro four-thirds (if you can wait a few months to have a choice better than the Lumix G1... I'd hope Olympus has one or two out by the summer).
