Kase 85mm f/1.4 AF 85mm
The bright f/1.4 aperture and 13-blade diaphragm create smooth, circular bokeh, while the STM stepping motor offers near-silent autofocus suitable for video. At just 580g, the lens remains portable and adds a de-click aperture switch plus customizable Fn buttons for tactile control during shoots. It’s best for portrait and wedding photographers needing flattering subject isolation, and videographers who demand quiet focus pulls and precise aperture adjustments.
