Does anyone know if Nikon uses the lossy highlight compression on the D500 that they do on the mid-range DX bodies like the D5x00 series?

same question for the D7200 - Thx

Not sure if this answers your question, but the D500 can shoot 14 bit uncompressed NEF at most, the D7200 can shoot 14 bit lossless compressed NEF at most, and the D5500 can shoot 14 bit compressed NEF at most. So in terms of compression the D500>D7200>D5500.

Just to clarify a little bit for others that might be reading, there is literally no difference between uncompressed and lossless compressed as far as the actual data goes, so D500 would = D7200 in that regard based on your above scale. The sole difference is file size. The only reason someone would use uncompressed RAW would be for very specific compatibility issues with RAW converters or some other similar scenario, as they are identical regarding quality or processing leeway.

So the transfer will not affect the raw files for either the D500 or D7200 (right?)

It is only the D5x00 series that can suffer some highlight degradation from the transfer (?)

D500 ~~ D7200 > D5x00

i don't know what you mean by "the transfer", but:

- lossless compression - no effect at all. ""lossless"" means just that, much like a .zip file.
- compressed - some ""visually lossless"" reduction of highlight detail. Might affect recovery of nearly-blown highlights.
- 14 vs 12 bit - some ""visually lossless"" reduction of shadow detail. Might affect recovery of shadow / dark areas.

The D500 will do "lossless compression" in either 12- or 14-bit.

Right, good point. And the D500 does allow you to use lossless compressed, so you can choose to benefit from those smaller file sizes anyway.
