Experiences have been rising that the brand new Nikon Z6 III may need a extra restricted dynamic vary than the previous Z6 II. This commentary was made by William Claff over at Photons to Pictures who does in-depth testing of digital camera sensor efficiency, and many extra moreover. Claff’s findings present the Z6 III maxing out at 10.44EV of dynamic vary at ISO 100, in comparison with the Z6 II’s 11.26EV on the similar sensitivity. The Z6 III continues to path its predecessor by 0.6-0.7EV till ISO 800, the place the 2 cameras then carry out very equally:
Now, Claff evidently is aware of his stuff and has been testing sensor efficiency for a few years, so I am not about to criticize his outcomes or testing methodology. However what I can say is after I lab examined the Z6 III, I discovered that (in distinction to Claff’s outcomes), the Z6 III’s dynamic vary was nearly similar to that of the Z6 II at decrease sensitivities, though the brand new digital camera did path the earlier era by 0.5-1EV at ISO 6400 and above.

Whereas that is shocking and disappointing, in my view the extra noteworthy distinction between the 2 cameras is their sign to noise ratio efficiency – aka how a lot picture noise every digital camera produces at a given ISO sensitivity. In our sign to noise ratio check I discovered the Z6 III and Z6 II generated very related noise ranges at decrease sensitivities, however at ISO 1600 the brand new digital camera begins to provide noticeably noisier pictures than these from the Z6 II, and this pattern then continues as much as ISO 25,600 – our highest examined sensitivity.
