This is my first Milvus Zeiss. I prefer the feel and the look of the Zeiss Classic Series of lenses and are using several in ZF Nikon mount. ZF mount more for the aperture ring control. I was offered a good price for this new Milvus 50/2 Makro Planar and so I got it. The first impression of the build quality of the Milvus is really overwhelming. Although the Milvus seems to have a modern 'plastic' look, the actual feel is actually not so. Very solid feel, very well built indeed. The two Milvus maro lenses are the only ones with the 'ZEISS' and 'Makro Planar' engraved at the side of the lens, rather than at the front where the filter thread is.
