I find it strange people are complaining about both the file size and slow shooting speed ("only 4fs"). I would think that the larger file size would make shooters want to slow down and compose their work more carefully, wait for the decisive moment and spend more time on photography and less on shooting.
I find the most intriguing feature to be the time lapse. But I am wondering if it is using the electronic shutter or the mechanical one to grab the image. If mechanical, it will hasten an early death of the camera, even with a shutter rated at 200,000 actuations.
I advanced ordered, but that was Tuesday. Wednesday, I had early buyer's remorse and thought about canceling. Today, I'm letting it ride. I am not about to give up my D700, regardless of what I do.
