If the Zeiss Milvus 135mm f/2 Lens featured autofocus, it would be a must-have lens for all serious kits. [..] The image quality coming from this lens is so high that, it seems to me that Zeiss could have used yellow paint, emblazoned it with the Otus brand name and charged double the price. Still, the price is not low, the lens is not light.
It is fairly large and definitely heavy [...] Despite these very real challenges the lens is a masterful option for those looking for the ultimate 135mm lens. [...] Images look great without being touched.
