@ heinrichvoelkel In my view the D800e that I used in my trip to Iceland required very good glass to shine.
And so I used two Zeiss lenses the Distagon 21mm and the Planar 100mm and two Nikon lenses the 24-70 and the 70-200. Loved the color of the Planar, absolutely great tonal range from the start.
@ mitchino It can be subjective to say what may someone may find deteriorating. I would say I can print very well on A1 with the Mark III. Having said this I tend to be quite difficult to please with print quality.
For tonality the most important thing is good start at the Raw process level, color correction and some separation at the Raw stage is key. After that I try to create further tonal separation when necessary in varying ways. However from this point on (in PS) I would say it's sort of an illusion of better tonality that can be achieved as opposed to actual better quality. Sometimes illusion works but it can be tricky and for those who don't print or mostly judge images online even more so. In any case there is a lot to be said about tonalities.
