See my Fujifilm GFX wish list.
This series from f/2 through f/11 looks at a host of lens behaviors using a strongly backlit subject in deep shadow. The ability of a lens to maintain contrast in the face of such backlighting is critical to being able to make a faux HDR image using the inherent dynamic range of the camera. The Fujifilm GFX has the requisite dynamic range, but the lens plays the key role in keeping black areas black.
Also looked at here are sharpness and depth of field gains and color correction on out of focus foreground and background.
Includes images up to full resolution from f/2 - f/11.
I could not even contemplate yanking on the raw file as hard as was done here with the Canon 5Ds R, or the Sony A7R II—not without a lot of noise and brittleness showing up in the image quality. But the the GFX pulls it off without breaking a sweat. This kind of quality makes me lust after a GFX, because Sony and Canon cannot compete with it, and even the Nikon D810 would be hard pressed to manage it (and be 36 megapixels, not 50).
