And yes, you can feel that difference, particularly since the older lens on the FTZ puts the added weight farther forward.įocus is handled by a stepping motor, and you have a switch on the lens to force the lens to stay in the macro range (0.29 to 0.5m).

Nikon paid close attention to weight and we've dropped 120g in the process ( plus the FTZ weight), so the new lens comes in at 22.2 ounces instead of 26.5 (plus FTZ). However, it will save you the weight of the FTZ adapter, and then some. The new lens is 140mm long (versus 116mm of the F-mount version). If you were hoping to save the size of the FTZ adapter, you won't. Nikon just adjusted their approach slightly, and the difference isn't meaningful in practical terms.

I wouldn't read too much into this: at close macro distances most lenses use a hybrid optical approach that impacts focal length rather than using a full focus pull (to keep the lens from extending too much during focus). The aperture diaphragm is 9 rounded blades.įocus distance has changed slightly, too, with the new minimum focus distance being 0.29m instead of 0.314m (that's right near one foot). The front element, which is ever so slightly convex, is also given a fluorine coating to help it slough off water and other things.Īs with most macro lenses from Nikon, the minimum aperture is f/32, not f/16 or f/22. As I've written before, these types of coatings address different shortcomings of air-to-glass transmission, and it's nice to see Nikon using their full arsenal of current technology. The published MTF values show a "sharper" lens across a broader set of parameters, and the difference isn't subtle.īesides the changes in optical design, the 105mm f/2.8 S gets ARNEO coating in addition to Nano coating. While there are similarities in the two designs, it's clear that the Nikkor engineers were looking for ways to improve performance. The F-mount was 14 elements in 12 groups with 1 ED element, the new Z-mount version is 16 elements in 11 groups with 1 aspherical and 3 ED elements. Optically, the new S lens is somewhat different than the last F-mount version, and more complex.
