DZO Arles Zooms

DZOFilm built the Arles Zooms around a four-group linkage optical system and a quad-synchronized zoom mechanism that it says holds image-field performance, aberration correction, and resolving power steady through the zoom range, even wide open. The 25-75mm uses 22 elements in eight groups, including seven ED and five HRI elements. The 65-180mm uses 20 elements in eight groups, including seven ED and two HRI elements. DZOFilm says these control chromatic aberration and field curvature while holding contrast, and it rates both lenses for 8K resolving power based on its internal testing. Both are designed to minimize focus breathing, with 270° of focus rotation for accurate pulls. DZOFilm describes the rendering as low in saturation with natural skin tones, and at wide apertures the look is soft and lower in contrast.
