[QUOTE="WayneF, post: 465071, member: 12496"] That is a petty big subject, which needs specifics instead of generalities, but start here: [URL="http://www.google.com/search?q=nikon+lens+mount"]nikon lens mount - Google Search[/URL] There are generally two types of Nikon AF lenses. Older AF, that are driven by a motor in the camera body, called AF. Newer lenses, called AF-S lenses (and there were a rare few AF-I lenses), with AF motor in the lens (driven electrically by body). The D810 and other premium bodies work fine with either version AF. Several economy bodies (D3100, D5200, etc) don't have the body motor, so cannot do AF with non-AF-S lenses So the answer can be very different depending on camera model. Older Nikon lens (F body, around 1960) were before the AI version, not so-marked, but informally called non-AI. The mount is the same but these non-AI are NOT compatible with todays DSLR bodies. It is said that damage can result from trying. Around 1977, then AI lenses. Older lenses could be modified to be AI compatible. Then around 1992, lenses started having a semiconductor CPU chip in them to report ID, maximum aperture, and focus distance (called D lenses). Those without this CPU (non-CPU lenses) can be compatible with the D810, but requires a special Non-CPU menu in the camera (D810 manual page 229). All lenses introduced since 1992 have the CPU chip. Special stuff, like telescopes, do not. Here is one description about identifying AI or non-AI: [URL="http://support.nikonusa.com/app/answers/detail/a_id/5366/~/what-is-the-difference-between-an-ai-lens,-an-ai-s-lens,-and-non-ai-lens%3F"]What is the difference between an AI lens, an AI-S lens, and Non-AI lens? | Nikon Knowledgebase[/URL] One quick ID is the old AI lenses had a double row of aperture markings, the rotary selection dial, and a second row of marking at the back of the lens. The rear row of markings were to be visible in the viewfinders of the day. See the Compatible Lenses section of D810 manual, Starting on page 419. [/QUOTE]
