[QUOTE="Horoscope Fish, post: 240011, member: 13090"] [B][CENTER]Decoding Nikon's Lens Code[/CENTER][/B] [B]AI, AI-S:[/B] Nikkor lenses produced after 1977 have an automatic indexing feature that eliminated the need to manually align the aperture ring when the lens was mounted. The first lenses to include this feature had the AI or AI-S designation. However, all optics introduced after 1977 have automatic indexing (except for G Series lenses, because they have no aperture ring), whether that's included in the lens code or not. [B] E:[/B] Nikon's Series E lenses are bargain-priced optics with great image quality, but less rugged mechanical innards suitable for use by non-professionals. They frequently include aluminum or plastic parts where brass is used in the most costly Nikkors. However, their lens mounts are all metal, so Series E lenses are more rugged than you might think. [B]D: [/B]When a D is included in the lens name, the lens is capable of communicating focus distance information to the camera, which supposedly helps with 3-D matrix metering and flash photography. [B]G:[/B] Lenses with this marking have no aperture ring. The aperture must be set by the camera, either automatically or by holding the EV/Aperture button and spinning the command dial (on the D50). The only caveat you should know is that these lenses cannot be used on older cameras that require an aperture ring. [B]AF, AF-D, AF-I, AF-S:[/B] Various AF designations show that the lens is an autofocus lens. The secondary code letter provides additional information: D is a D-type lens; I focuses through an internal motor; S focuses or fine-tunes focus manually even with AF engaged. [B]DX:[/B] All DX lenses are designed exclusively for use with digital cameras having the 1.5x crop factor.
