D 800E Wedding Photographers please comment

This argument about file sizes is slightly uninformed.

If you set your D800E to 14bit compressed lossless you get around 42-47mb files. I read D600 files were around 25-30mb. That's not a lot of difference.

If those sizes are still too large there is always 12bit lossless compressed for even smaller file sizes or DX even or various other slightly smaller crop modes that D800 allows you to take.

It seems the D800 is a bit ahead of the average computer and its file handling ability.

It does take a little while to transfer images from NX2 though I must admit but I don't know how much faster a D600 would be - perhaps 50% based on file sizes?
