I know this ain’t going to be pretty!

DSC00680

So I have a camera with a problem.

As you can see there is something wrong with the shutter blades … yeah.

This ain’t no simple blades popping out of the slot issue, this one I know is really broken.

Well time to take a look inside.

I was advised that getting to the shutter on a Nikon FM2 was not that difficult … there is a pretty good video on YouTube showing how to get the mirror box off.

Now I have to warn you that the images show some parts that were taken off already … I don’t tend to document in sequential order as I go …

Ok, lets start from the top.

DSC00713First, remove rewind knob using the typical method is used. Under it is a tension clip thin and a washer.

The shutter speed dial is secured with 3 screws. Remove and pull off.

Advance lever … first remove cover leatherette, then unscrew the cap. Remove the lever and be aware of the spring underneath.

Finally the top cover, it is held on by five screws, pull off top plate.

DSC00714Note that there are two plastic parts, one on each side of the prism that will fall off as they are only held on by the top cover.

For a mechanical camera, the FM2 has a complicated electronic light meter system … it actually has dual SPD photosensors, so there is a lot of wires. I decided to loosen some wires by desoldering some of them.

Remove the bottom plate. Three screws.

DSC00718I desoldered the black wire to battery terminal (blue wire), red and orange to winder contacts … loosen white wire from glue.

Now open the back door.

Remove the single black screw.

DSC00715OK, now the front of the camera.

The lens mount … four screws.

There is a metal ring underneath … note it’s orientation … then take it off.

DSC00716Now there are some things left … there is a plastic ring with string attached and an inner metal ring that is tapered – thin side down.

DSC00717You can pull those out and put the one with the string aside.

Now you can unscrew front plastic cover two screws … pass plastic ring through it.

Self timer lever … take off the leatherette. Remove screw and self timer lever.

OK getting close now. Remove front two leatherette patches.

There are five screws that hold the mirror box/prism on. Remove.

Annotation 2019-06-16 163208There are three screws on either side of the viewfinder port … and one below the shutter speed dial that has a spring (not the other screw).

OK, this is the hard part … peeling off the top and moving it aside. You will encounter some old sticky foam.

Now here is where the video (I noted at the beginning) ends.

The shutter housing and the gears can be remove just by taking off the two brass top screws … do a little wiggling and pull off shutter.

DSC00720The back side of the shutter housing plate is held on by a couple of screws.DSC00721Then slide off.

 

 

 

 

More layers, more screws.

Make note of the tiny springs that are attached to both of the shutter blade sets.

DSC00725

You can now remove both sets of shutters.

DSC00722

So here is the second curtain. One of the blades actually snapped the metal into two … well that is not something you repair, just replace.

Putting the camera back together was not all that difficult either.

This one is now relegated to the parts bin … just to wait for another FM2 or an FE2 to land in my lap.

Hmm, I just realized I didn’t even check if the light meter was working …

The Nikon FM2 … the speed demon.

1977 … Nikon makes a mechanical version of the FE called the FM. I think they did this to appease all those old foggie shooters pining for a lighter version of their F2’s. It had the similar body design as the FE so it was small/compact.

This post is about the successor … the Nikon FM2. The FM2 has quite the following and it deserves it. It is a very well made camera that carries on Nikon’s F legacy.

The FM2 had upgraded to a super duper dual silicon photo-diodes, and the super-super duper vertically traveling titanium shutter that could achieve 1/4000s!!!! Wow (I think Copal made the shutter for Nikon). The early FM2’s has a honeycomb pattern on the blades … sometime in 1989 they got rid of that and replaced it with unpatterned aluminum alloy blades that were on the FE2.

The original 1982 FM2 is not easily found as it only lasted a year before being slightly changed in 1983. The updated version is still labeled as FM2, though like the Canon F-1 it is considered the FM2n (the serial number starts with N) … the visual difference is the increase in flash sync from X200 to X250 on the shutter speed knob.

The FM2 has been a favorite among Nikon shooters for may years due to it ruggist-ness- nesss. Many are still working perfectly to this day, even after being discontinued in 2001.

Unless you put your thumb through the shutter …

Nikon FE … lacks power.

So, I got a Nikon cause it was listed as “for pieces or repair”. I’ve don’t tend to get more modern cameras but it was going for a pretty fair price so I though I would try to repair one of these more electronic ones … well I was disappointed after I showed up !!!

The camera does not power up … hmm. It is missing a battery holder/cover. So I hunted around and found a replacement part …  and a couple of LR44 batteries … I really didn’t even have to clean the damn thing.

The only reason I am posting this is because it is a nice looking camera that also works great.

The Nikon FE came out 1 year after the FM, in 1978 … hmm, this camera is younger than I am. It shares much of the same body construction, and it is much more electronic. The FE has an electronic shutter (plus mechanical 1/90s + bulb) and offers aperture priority and manual exposure using a match needle system. It, like the FM, can handle Ai and non-Ai lenses (unlike the FE2) using stop-down metering.

You will notice that, like the FM, the model name is discrete. Nikon decided not to splash it in bold letters on the front like most other cameras (look for the tiny FE/FM beside the serial number on the back) … hmm, I wonder why? … oh, and it has a little dent (wasn’t me).

N.K.K.K. on … no I ain’t stuttering.

Nippon Kōgaku Kōgyō Kabushikigaisha … Japan Optical Industries Co., Ltd, ah this is the name that many of you people know of as Nikon.

Nikon’s origins begins underwater … well, sorta. Back during WWI a company named Mistubishi was making submarines for the Japanese Navy. During that time Japan did not have their own optical manufacturers to build the periscopes … so the President of Mitsubishi decided to make a company that could to remove reliance on foreign parts.

Nippon Kogaku was created in 1917 from a merger of three companies to produce advanced optics for the nation of Japan. Now I am not going to go into a lot of detail about them … sooo much has been already said already, I just point some things out.

  • 1919 – Nippon Kogaku invites German optical specialists over … not so uncommon later in time for many Japanese companies to take advantage of the advances already produced.
  • 1929 – The Anytar 50cm F4.5 was created.
  • Konishiroku (Konica) started using NKKK lenses on their cameras
  • 1932 – The Nikkor brand name appeared.
  • Nikkor lenses start showing up on various Japanese and European cameras
  • 1935 – A Nikon lens appears on a a Canon camera.
  • 1946 – A Nikon camera is made
  • 1959 – The F is made.
  • blah, blah, blah … eh, just Google it.
