This is an Obscure Lens. It is not "quite a zoom", it is variable focal length. It does not compensate focus as you change focal length, so- change focal length at any distance except infinity and you need to re-focus. The aperture is constant, max aperture is F2.8. The lens is multi-coated. Less elements and simpler than a zoom.
Not a cult lens. Best described as a curiosity of optical design. This lens came out in the mid 1970s, was an expensive lens.
Wide-Open, 85mm.
At F4,
12 elements in 9 groups, the multi-coated optics do well on the Nikon Df. This example is a pre-Ai lens, picked up in mint condition for $95. The SN puts it at one of the first made, well below 1000. The lens was later brought out in Ai mount. It is available in most popular SLR mounds of the day.
