Nikon's classic professional standard zoom — 28-70mm f/2.8 that served pros before the 24-70mm.
The Nikon AF-S Nikkor 28-70mm f/2.8D IF-ED launched in 1999 as Nikon's professional constant f/2.8 standard zoom. It served as the workhorse zoom for professional Nikon photographers until the 24-70mm f/2.8G replaced it in 2007.
Optically very good — sharp throughout with constant f/2.8. AF-S motor for fast, quiet AF. ED glass for chromatic aberration control. IF internal focusing. The 28-70mm range is slightly narrower at the wide end than the later 24-70mm.
Nikon F mount with 77mm filter thread. Approximately 935g. Gold-ring professional designation. No VR. Full-frame coverage. Minimum focus distance 50cm. Professional weather-resistant construction.
Available used at mid-range prices. The 24-70mm f/2.8G succeeded it with wider coverage. The 28mm starting point feels limiting after using 24mm. Still a sharp, reliable lens. For F-mount users wanting an affordable constant f/2.8 professional zoom.
