Has anyone cropped the D800 images to DX size and compared them to the D300? I just wonder if the megapixels on the D800 (and maybe D4) obviate the need for a DX pro body? Sure it's nice to have a DX body alongside an FX body to have the best of both worlds. But for most situations the extra pixels of the latest FX bodies are superfluous unless you are doing mega size prints ....or cropping!
That is a good point. I can do a test.

Do you want an in-camera crop to DX size from D800 (4800x3200 pixels)= 15.4MP.
Or a 12mP central portion as a comparison of how much better it is than a D300?.

The only back up body I need these days is the one to carry the gear! :-)

Thinking about this...it needs to be compared to the D7000 (ie the latest iteration of DX sensor) not the D300. And I think Ed answered that point already.

Comparing it to the D300 only confirms that cropping is as good as the status quo. It doesnt take into consideration possible improvements in DX sensors. A D4/600 would pick up from where the D7000 left off.

Very interesting.
I cant believe how 'cropped' the image is from a DX sensor!!
I'm getting so used to the FX sensor.

Image taken with 17-35 f2.8 AFS on a D800.

Here is a full sensor image with the DX crop overlaid.

Here is the full FX image.

Here is a DX crop out of the FX image.

It would be interesting to compile an 'IQ ranking'.

For example options to achieve 800mm say.

1. D4 + 800mm prime ?
2. D800 + 800mm prime ?
3. ......Then feed in TCs with shorter primes, DX bodies and cropping in order of IQ.

It should be possible to plot IQ against cost. Then we could decide the most cost effective route to get the minimum quality level we want.

OK Eric. So are you going to pony up for the 800 prime?
