This is part 2 of a comparison of he Fuji 45-100/4 on the GFX 100 with the 24-70/2.8 Nikkor S on the Z7 at 45mm, 63 mm, and 100mm for the Fuji lens, and 35mm, 50mm, and 70mm for the Nikkor. This post will look at the 50/63mm shots.
Here’s the test scene, with the 45-100/4 on a GFX 100, and set to 63 mm and f/4.
Target distance was 14 meters.
- The heaviest RRS legs
- Arca Swiss C1 head
- ISO 100 for the GFX 100, and 64 for the Z7.
- Electronic shutter 1/10 at f/4, 1/5 at f/5.6, and 1/2.5 at f/8
- 2-second self-timer
- AF-S, medium spot size
- 3 sets of shots at each test condition
- Developed in Lightroom
- Picked best shot of each test condition
- Sharpening amount 20 radius 1, detail 0 (much less sharpening than the default)
- Adobe Color profile
- White balanced to grey background
We’ll look at some tight crops at about 130% magnification for the GFX 100, and enough more than that to make the angle of view the same for the two cameras.
In the center:
Both lenses are putting down detail the cameras can’t resolve. The Z7 seems to be more outmatched.
The situation continues. The Fuji images have greater resolution, and less aliasing.
There’s enough diffraction that there’s little aliasing in the Fuji image.
In the upper-right corner:
Again, the Nikon corners are darker. It’s even worse than it looks, because, as you can see by looking at the center images, the Fuji images are brighter there. The Fuji has better resolution and less aliasing.
The aliasing isn’t that different, indicating that the 45-100 is sharper.
My conclusions are the same as before:
- The Nikon 24-70/2.8 Nikkor S is a heck of a lens that needs a 100 MP body to really shine.
- MF is once more better for even illumination.
Feel free to mix and match the f-stops if you want to look at equivalent stops.
