Sorry for the display problem. I posted the review then had to go out and couldn't fix the problem till I got back to a computer with editing software. Chris was kind enough to handle it for me.
As for the topic of histograms, I did indeed mention it...
– The highlight warning (when activated) is now very precise. It exactly matches the clipping indication in Lightroom, and is not influenced by the JPG setting (if any) as it is on so many cameras. In fact, if you do not have JPG generation turned on the settings for colour space aren't even available, which almost all other cameras do – the source of no end of confusion to many photographers.
