[QUOTE="WayneF, post: 340271, member: 12496"] I don't think if a D or G lens is an issue here, esp not about color. Every Nikon lens introduced since 1992 is a D lens (with the chip in them, i.e., a CPU lens). Those that "say" D just don't have anything else to say. Those that don't say D just have more to say, newer features like a G lens, etc. A G lens has no external aperture setting ring, aperture can only be adjusted from the camera dial (and a G lens is also a D lens. but I think none say D and G). The D chip reports lens info, like zoom and model and max aperture, and specifically focus Distance, and all since 1992 do this. FWIW, the D chip reports barrel rotation for focus distance, and zoom lenses can have trouble reporting distance, it can be wrong at many focal lengths (high dollar lenses might fare a little better). For one example, the 16-85mm zoom, focused at 3 meters (10 feet), it reports 2 meters at 16mm, and reports 3.6 meters at 85mm, when both are focused at a measured 3 meters. It seems a questionable feature, but nevertheless it can influence TTL BL direct flash exposure (example limits a 3 meter distance to only 2 meter flash power at 16mm). But all Nikon lenses since 1992 are D lenses. It can be, and is, assumed. [/QUOTE]
