Z6 & FTZ 2 Stops Darker than D700 for exact same settings

Hi there,

I haven't seen this spoken about before but hopefully someone can advise.

I only have F Mount glass so I'm using the FTZ adapter and it seems that regardless of the lens I use (Nikon AF-S 14-24mm f2.8, Nikon AF-S 24-70 f2.8 or Nikon AF-S 70-200mm f2.8 VR I), the Z6 exposes around 2 full stops darker than on my D700.

Does anyone know if this has to do with using the FTZ adapater and F mount glass? I unfortunately don't have any Z lenses to test this with. Or is this a Mirrorless vs DSLR thing?

I noticed this testing out the Z6 on two portrait shoots in a forest and it was setting the ISO way higher than I'm used to. Using my D700 for the exact same scene used much lower ISO to get the same level of exposure. On both shoots I kept on switching back to my D700 to hedge my bets and thank goodness I did as the Z6 was consistently pushing 3200-8000 ISO values where the D700 was mostly 200-800. I know the Z6 is great in low light but it didn’t seem to handle the mixed lighting of the forest too well. There is a quite a bit of noise in the shadows including even the suttle shadows on the subjects face, so they can’t be done pushed too much without really losing quality.

Here is a simple test using Z6 and D700 at the same settings, taken 15 seconds apart and in the exact same lighting. Exif data confirms same settings on both:

  • Exposure: 1/200 at f2.8
  • ISO: 1250
  • EC: None
  • Focal Length: 150mm


D700 - 1/200 at f2.8, ISO 1250, Nikon AF-S 70-200 f2.8 VR I


Z6 - 1/200 at f2.8, ISO 1250, Nikon AF-S 70-200 f2.8 VR I

I then pushed the Z6 image's Exposure in Lightroom by +1.8 and this is the result:

I am renting the D750 today and will test that out today in the same forest so will see if that exposes like the D700 or Z6.

Thanks everyone!
