Fujifilm GFX: Moiré Examples + Astrophotography
Related: astrophotography, digital artifacts, Fujifilm, Fujifilm GFX50S, Fujifilm medium format, Fujifilm mirrorless, medium format, moiré
Like most medium format cameras, the Fujifilm GFX has no anti-aliasing filter. With high performance lenses, this can lead to severe moiré problems that make images unacceptable for professional use.
Problem areas include fabrics, architectural features like window screens, and in general anything with repeating spatial frequency at a reproduction ratio that puts that spatial detail at close to sensor resolution.
Update: I’ve added examples with a metal-siding building and brush.
Sample image was shot at f/5.6 with the Fujifilm GF 32-64mm. That moiré shows up is a testament to very high resolving power and micro contrast of the lens. At the time, I had no inkling that the image would be severely degraded by moiré, but the results are truly ugly and should be understood as something a professional may have to deal with and be aware of for some subjects.
