Prior to this model 24-120, I owned two previous models; the F 24-120 f4G VR, and the first 24-120 (non VR). I hesitated buying this lens, because previous models image quality fell off noticeably at focal lengths above 70mm (the first 24-120), and 85mm ( 24-120 f4 G VR). I was kind of hoping that Nikon would follow their original lens plan and introduce a 24-105 f4, like the excellent Sigma and Canon renditions. I surmised (ha ha) that the shorter Zoom would give me excellent image quality throughout the range with only slight fall off at the longest end. But that is exactly what I get with the Z24-120 f4S.
I also expected the new model to have lens based VR and build quality on par with the Z 24-70 f4S. Wrong again... and again. I thought that a lens reaching out to 120mm would need lens based VR in addition to IBIS. It was a little disappointing that it didnt. Besides the Z6II, which has IBIS, I also own the Z fc which does not. I've used lens and camera setups for years that didn't have VR and / or IBIS, so not having VR was a luxury I could do without if I really want the lens. But it would've been nice to have that stabilizing mechanism for the smaller lighter camera.
The 24-70 f4S is a well built lens. While it feels cheap, it is actually a robust tool. However, its build quality pales when compared to its sibling, the Z 24-70 f2.8S. I fully expected the Z 24-120 f4S to have the same build quality as the 24-70 f4S. I was wrong to my happy surprise. Except for the lens OLED display, the Z 24-120, has the build quality of the 24-70 f2.8S. It has the same controls, such as L-fn, and function ring (useless), as well as the focus and zoom rings. However there is an inconsistency in the placement of those rings between Z lenses. On the longer zooms ( in my case the 100-400, and the 70-200 Zs), the zoom rings are closest to the front element, while on the the shorter Zooms (24-70S f2.8, and 24-120 Zs) it is the focus ring that is closest to the front element. On three of my zoom lenses, the Zoom ring is considerably the widest of the rings, but on the Z 24-70 f2.8S, while the Z ring is only slightly wider. So besides screwing with your muscle memory, Nikon also screws with your touch sensitivity. The Z24-120 also doesn't have a lens hood that locks in place and a button to unlock it, which the other three feature.
How does the Z 24-120 image quality compare to its predecessor, the 24-120 f4 G VR? In my opinion, the Z out classes the F model at every focal length, but especially at the longest and the widest lengths. It is no surprise that one can use most Z lenses wide open and still get sharp photos. It is also no surprise that image sharpness in the corners and edges hold their own, quite well. This lens is no exception. While it cannot compare to the Z 1.8 primes, for image quality or bokeh, it is not far off those marks. The Z24-120 f4 S is a convenience lens. It gives 7 marked focal lengths and every mm between 24mm and 120mm in one lens, and also gives you very good usable image quality through out its range. Are there issues? Sure. Bokeh isn't great, corners are sharp from 24-70mm but softer from 70-120. But in real usage, this lens is worth it.
