This is the 2 ring version, not push-pull. In excellent+++ condition. No issues or blemishes. Includes: HB-17 hood, front and rear caps, Nikon L37c UV filter, original box, Nikon leather case w/strap (unused), Kirk LP-4 tripod foot and Lowepro lens case #3. Incredibly sharp images from this lens. Works on F6, F5, F4, F100, F90 and F/N80 bodies. Also on FX and DX bodies. Selling because I just don't seem to use tele's anymore. I think I only used it once in the last year. $775 plus fees. If interested, contact me with questions. US lower 48 only, at this time.
