Various DR measures

Marrianne, I am used to seeing the dpreview dynamic range results. Are your estimates of the D4 dynamic range comparable to theirs or different?

My numbers are what's referred to as "engineering DR" which is simply the ratio of the highest signal value, to the read noise at base ISO.

If you are referring to the strip charts that DPreview publish, that's an assessment of the JPEG output rather than the RAW data, so is quite a different metric.
