A 'Gift' from a 90 year-old Camera Club Member who is having a 'Clear-out' Prior to moving. The NIKON FM is one of a series of that period including the FE, FM2 etc mine is the 'Black Paint' version and I repaired the 'Brassing' on body due to Professional use and renewed the light seal foam in camera back. Manual Exposure only with RED LED's on right of viewfinder -- when more than one is shown turn aperture ring until only one is shown opposite the selected shutter speed . Metal Vertical Running Shutter 1-1/1000th with 'B' , maximum flash synch at 1/125th. Delayed action puts mirror up first to prevent vibration. There is a Double Exposure button next to lever wind, which acts as battery -off when pushed in flush. you have to have wind lever out to fire shutter. ASA range 12-3200. There is a 'Depth of Field' Preview lever on lens mount which is the NIKON bayonet AI with small button for 'Stop-Down' metering. which dis-engages the auto-aperture lever. There is a PC plug + Hot Shoe on top. The LENS shown is the 'Micro-Nikkor 55mm f2.8 which focuses down to 0.25 meter same-size reproduction. Sharp at 'Medium Distance ' as well as 'Macro'
