Distinguished by speed, the Ibelux 40mm f/0.85 from Kipon is an exceptionally fast prime lens for Sony E-mount mirrorless cameras. The impressive f/0.85 maximum aperture affords extensive control over depth of field for isolating focus and it also benefits working in low-light conditions. The ten groups in eight elements optical design incorporates a front concave element, which helps to reduce color fringing and various aberrations in order to achieve a high degree of sharpness. The all-metal construction realizes a rugged physical design, and the lens barrel's exterior also incorporates both depth of field and focusing distance scales for more accurate focus control. Additionally, a ten-blade diaphragm contributes to a pleasing bokeh quality to suit working with shallow depth of field techniques.
