Zeiss Milvus 2/50M review: Excellent optical performance

Like its predecessor, it is the fastest 50mm full-frame macro lens currently available. It adopts the same optical construction of 8 elements in 6 groups, complete with “floating elements” — elements that move in relation to the focus distance — to improve optical performance at close range. Minimum focus is 9.45” (24cm), with a maximum magnification of 1:2 (half life-size).While the optical design hasn’t been altered from the original, it has new lens coatings and maintains the all-metal barrel, complete with smooth coverings on the focus and aperture collars on the Nikon mount version, somewhat externally reminiscent
