So the Fujifilm GFX 100 has a 100-megapixel medium-format sensor. Who could possibly need this much resolution, and can this camera really capture detail that others can’t? How do you even test this kind of capability?

We needed to find out for our Fujifilm GFX 100 review (just posted).  On Digital Camera World we prefer to use an optical test chart. This chart includes extremely fine converging lines that eventually start to merge as the camera’s resolution runs out. Our resolution figures are based on a visual assessment of when this happens.
