The Zeiss Batis Sonnar T* 2.8/135mm is a full-frame (FE) telephoto prime lens for the Sony E-mount, announced by Zeiss on April 24, 2017.[1]
Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 202.5mm.
The lens features a minimalist weather resistant plastic construction with a matte black finish and a rubber focus ring. On the top of the lens is the OLED display that highlights the focus distance and depth of field range of the lens, which can be set to display at all times, never, or only when focusing manually.
Optical quality
The Batis 135mm is sharp wide open, with consistent results across the frame.[2] Chromatic aberration is "very low" at less than half a pixel wide open at the image edge.[2] The lens has its sweet spot at around f/4.[3] Vignetting is "far from severe", but there is some noticeable pincushion distortion[3] that can be eliminated with in-camera correction or raw processing.[3]
