Difference between FM2 and FM2n

[Josec]

Sorry for my ignorance, but can someone tell me what the difference is between an FM2 and an FM2n?
Thank you!

The major difference is the flash sync speed was increased from 1/200th to 1/250th. Additionally the 1/200th speed of the FM2 was not metered, being between standard speeds. 1/125th was the highest metered speed the FM2 could employ.

Also the max shutter speed of the FM2 is 1/1000 sec if I recall right, this was increased to 1/4000 sec on the FM2n.
Another issue that most of the people overlook , and is not present in all FM2n, is the change in the design of the shutter curtain. On the FM2 is the honeycomb style and the early FM2n also share the same design. Problems with such design gave birth to the aluminun blades shutter curtain in the late FM2n.

Actually the FM had a max shutter speed of 1/1000 but both FM2 and FM2n have a max of 1/4000.

Going through my archives

I find that Tom is right, the max. shutter speed in both is 1/4000 sec.

The max metered sync speed on the FM2 is indeed 1/125th and of course the 1/200th is unmetered.However, I'm pretty sure the cameral will also sync at any speed slower than 1/125th just like the FM2n will sync at any speed slower that 1/250th.
