Fuji Gfx 50r Vs Nikon Z7

All camera comparisons have potential for error or inconsistency between cameras. Here are the ones we identified in this test and tried to minimize:

Exposure

ISO 64 allows the Nikon to tolerate 2/iii more calorie-free per unit area of its sensor, compared with the base ISO of 100 on the Fujifilm. Conveniently, this 2/3EV difference is very close to the difference in F-number required to give both cameras the same depth-of-field.

The logical implication of this is that the amount of additional 56% low-cal
per unit area
the Z7 sensor can tolerate comes close to countering the GFX’s 68% larger sensor area (the crop gene, which is calculated from the diagonal of the sensors go far wait like a closer match, but the different attribute ratios of the fries means the GFX’s sensor is slightly larger than the ingather cistron implies).

Differing aspect ratios

A four:3 image can’t be perfectly overlapped with a 3:ii one, but the framing of these shots has an overlapping region that uses 95% of the GFX’s paradigm and 93% of the Nikon image, so the comparison is almost as off-white equally it can be. The overall deviation in sensor area means that, even with the exposure difference, the Fujifilm will accept received around viii% more than light over its whole image, than the Nikon.

ISO accuracy

Nosotros suspect Nikon’s ISO 64 fashion is achieved by using some of the non-linear response that is normally unused by most manufacturers (promising greater DR capability past at the risk of slightly unpredictable results near clipping). To ensure a fair comparison, nosotros analyzed both Raw files using RawDigger and checked how far below clipping each tone in the paradigm is. We found they matched to around 0.1EV difference.

Microlenses

Some of the sharpness deviation betwixt the two cameras is likely to stem from the microlens on the GFX sensor having gaps between them. This maximizes spatial separation between pixels (and hence increases credible sharpness) but comes at the price of a greater take a chance of moiré.

Processing logic

Both shots were processed using the same colour mode, with effulgence, highlight and shadow adjustments tweaked to match effulgence beyond both images. Noise reduction and sharpening was minimized in each case, with sharpening conducted manually in Photoshop before output.

These processing settings make use of more than 12EV of both camera’s dynamic range and requite an understanding of the performance you will go from both cameras if trying to apply near of their dynamic range, and highlighting whatever potential areas of difference betwixt the two cameras.

We don’t await anyone to procedure images using this little noise reduction but it reduces the risk that Adobe’s profiling is hiding whatsoever difference between the two. It also means that whatsoever bear upon of PDAF banding in the Nikon prototype is not bearded.
