Ditto Tom’s words.
Excellent reporting on the Nikon Pro Roadshow. Definitely saves me having to go to the one closest to me. The ISO button on the D4 was on the back, below the screen, not on the top left of the camera. This allowed housing manufacturer’s to make a left thumb paddle for the ISO, which was nice. The new position, as you say is more problematic for housing design. Yet being such a critical feature its ease of use will be a major differentiator in D5 housing ergonomics.
Thanks also for the BOOT show report.
