The lens designer is Takahiko Sakai of Tamron.[1]
The lens features a minimalist weather resistant plastic construction with a matte black finish and a rubber focus ring. Along with the Zeiss Batis Distagon T* 25mm F2, the Batis Sonnar 85mm was one of the first two lenses in which the traditional distance scale on the lens is replaced with an OLED display.[2] The OLED display is integrated into the top of the lens barrel, and highlights the focus distance and depth of field range of the lens,[2] which can be set to display at all times, never, or only when focusing manually.
