Did you read what he said? Last time I'm going to comment on this particular issue. He mentions that he could "crop later", just like you are saying that you could crop in on the FX shot. He isn't saying that he magically is getting more pixels or anything. Just that by switching into DX mode he gets the crop done automatically for him, when needed. Saving time in post-processing.
I still believe you are both saying the same thing of how DX mode works
You got it HappyCamp, we are saying the same thing.
So, I got a chance to use it at yesterday's wedding and it was pretty fabulous. When I twiddle to DX, I can still see the full-frame image thru the viewfinder, it just includes a DX sized rectangle overlay. Sometimes it was a smidge difficult seeing the rectangle overlay in the darkened reception room, when gunning for crowd reaction shots, but fortunately it blinks red when the shutter button is halfway pressed. Boom! Nicely framed pics of people laughing, smiling, clapping, toasting... without having to crop in post. Yesssss!
