I've added another small table to the lens acronyms page, as I keep finding that people have a difficult time distinguishing between Nikon's abbreviations and those used by other vendors:
| Nikon | Sigma | Tamron | Tokina | |
| Lens with motors | AF-S or AF-I | HSM | USD | (IF-S) |
| Lens with stabilization | VR or VR II | OS | VC | not applicable |
| Lens for Full Frame Cameras (D700, D3 series, F6) | (FX) | DG | Di | (FX) |
| Lens for Cropped Frame Cameras (all other Nikon DSLRs) | DX | DC | Di II | DX |
Items in parentheses indicate that these abbreviations are not normally marked on the lens itself. And that's a problem. Even this short table shows just how incomplete Nikon's own marketing is (why can't they mark FX on lenses?), and how confusing other's sometimes is (really Tamron, Di and Di II? II is normally used to indicate "newer" not "different").
