Thom's Commentary: I wasn't expecting to like the 24-120mm f/4 as much as I do. This Z-mount version makes the old F-mount versions look, well, old, tired, and incapable. This lens is good enough—that S designation is well deserved—that it introduces a clear conundrum for mid-range zoom lens users. Do you get the 24-70mm f/4, the 24-120mm f/4, the 24-70mm f/2.8, or maybe even the 24-200mm f/4-6.3? My answer is this: you get the 24-120mm f/4 unless small/light is important, then you get the 24-70mm f/4 (preferably at the kit lens pricing). You get the 24-120mm unless you absolutely need fast aperture and the sharpest zoom in the mount (24-70mm f/2.8). While a lot of you value that extra 80mm of the 24-200mm, let me state it outright: the 24-200mm isn’t in the same optical class as the 24-120mm f/4. I wouldn’t have predicted it, but the 24-120mm f/4 is turning up in almost every pro’s bag for its excellence coupled with flexibility. Recommended Read Thom's Full Review of the 24-120mm f/4 Lens
