    CDC? Not sure what that is? How did you go about chipping it? Id love to use it on my F5 or D600.

    Sorry about that brain cramp. It's CRC or Close Range Correction. By the serial number your lens (1972-March1975) is indeed a CRC lens as it was introduced in 1968. Pop the lens off the camera and look at the rear element while moving the focus to minimum distance.Towards the end of the focus range the rear element will move outward towards the mirror. This is what allows the short close focus,almost macro minimum distance.

    To chip the lens you'll need to remove the rear baffle and machine room on this lens. The chip can be bought on eBay for $30 or so. It's programmed for focal length and f stop using a Nikon Digital camera. Look around online or these guys can do it for you if you're not comfortable doing that kind of modification.

    You can use the lens on an F5 IF IT'S HAD AN Ai CONVERSION. I strees that because mounting a pre AI lens on the F5 will break the aperture coupling. But if the lens fits the FM2n w/o breaking anything (the little protrusion for aperture) it should fit the F5 as well. Only modes usable will be full manual and aperture priority. Metering is limited to center weighted or spot.

    Great info! It is an Ai lens. I made sure with the shop prior to buying. I was wanting a D series but honestly it wouldn't make that much of a difference in what I want to use this for anyway so I jumped on this one.

    In reality the sub-command wheel not active with an unchipped Ai lens attached is a good thing. The Ai lens aperture response to the camera's control is not linear and leads to exposure issues. So using the lens to set it will eliminate that issue.

    BTW check yer e-mail. There's a surprise in there.

    Thanks! I didn't have an FM2 manual either.
