The 40 mm view suits dialogue, documentary stories and portraits that retain environmental context this Micro Four Thirds version produces blue horizontal streaks around bright highlights.Anamorphic framing and flareThe constant 1.33x horizontal squeeze gives footage an approximately 2.35:1 aspect ratio after de-squeezing a 16:9 recording. The fast T1.8 aperture allows filming under available light and contributes to oval bokeh and subject separation. A minimum focusing distance of 0.60 m offers flexibility for foreground elements and detailed inserts.Autofocus and manual cine controlAn STM stepping motor enables autofocus and supported camera subject tracking, while an AF/MF switch allows a change to manual focusing. The 360° focus-ring rotation, cine-standard focus gearing and switchable click/de-click aperture control provide more deliberate operation for planned takes. A USB-C port supports lens firmware updates.Optics and matched riggingThe optical design uses 16 elements in 12 groups, including five cylindrical elements and one aspherical element, with an 11-blade diaphragm. A shared 77 mm filter thread and matched focus-gear positions simplify swapping compatible lenses on a rig.
