Nikon NIKKOR Z 24-70mm f/2.8 S II vs Nikon NIKKOR Z DX 24mm f/1.7
The bottom line
The Nikon NIKKOR Z 24-70mm f/2.8 S II is a zoom (24-70mm) and the Nikon NIKKOR Z DX 24mm f/1.7 is a 24mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.7 vs f/2.8) and lighter to carry.
