Shootout: Fujifilm GF 63mm f/2.8 vs 32-64mm f/4 — Pine Creek South Fork


On a related note, see Zoom or Prime Lens?.
A key question for the Fujifilm GFX shooter might be whether the GF 32-46mm f/4 can eliminate the need for the GF 63mm f/2.8 — skipping the smaller prime altogether, the one stop of lens speed not being particularly relevant versus just raising ISO one stop. I wanted to answer this question on my recent trip.
In terms of subject matter, this scene below was not my preferred subject of the three that were shot to cross-check, but it is the one that offers the most clear-cut view of what is going on. Moreover a far distance scene is the most demanding of any test, mercilessly revealing all weaknesses.
