This is a continuation of a test of the following lenses on the Sony a7RII:
- Zeiss 85mm f/1.8 Batis.
- Zeiss 85mm f/1.4 Otus.
- Leica 90mm f/2 Apo Summicron-M ASPH.
- AF-S Nikkor 85mm f/1.4 G.
- Sony 90mm f/2.8 FE Macro.
The test starts here.
In yesterday’s post I showed a set of pictures of Macbeth charts shot with the a7RII and each lens, developed in Lr CC 2015.4. The last set had each photograph white balanced to the third gray square from the left, and equalized for exposure in Lr.
Today I’ll show you what those last five images look like when graphed in one of the CIE chromaticity spaces. Since the differences are subtle, I’ve decided to show them as animated GIFs, which cycle through all the lens choices.
First up is CIE u*v*, which is the horizontal axes in CIELuv:
Now we have a similar space, the horizontal axes of CIELab.
Looks like the Batis and Sony made things more saturated, and the Leica made things less saturated, with the Nikon and Otus in the middle.
I don’t see how a lens can make things more saturated.
So surely what’s going on is that the lens with most saturated results has the least (subtle) veiling flare, and all the other lenses are reducing saturation relative to that one. Or is there something I’m missing?
I was just speaking in a relative sense.
