Is there a difference when shooting 14-bit compressed (lossless) vs 14-bit uncompressed? Does the compression time reduce fps? Pro of shooting compressed are obviously reduced image sizes, any cons?

When this topic came up for discussion for the D700 sometime ago, some claimed that the data lost was useful when trying to recover highlights. I don't know the truth, but "lossless" makes me more comfortable.

On the D800, according to NIkon (Still images/Movies common features)
http://imaging.nikon.com/lineup/dslr/d800/features04.htm

Compressed 14 bit averages 35.9 MB while Lossless compressed 14 bit averages 41.3 MB. That is about a 15% increase.

I'll stick with lossless.

Some time ago I try to see the benefits. From what I saw and heard its just more data the computer has to process for little to none benefit.
