Nikon FM, FM2, FM2n detailed review and demonstration

A detailed look at Nikon double-digit F series cameras Nikon FM and FM2 with a particular focus on FM2n. We also briefly mention the differences with FM3a.
I hope you didn’t miss our blockbuster series on the single digit Nikon F series on this channel. They are in the must-see category, like Star Wars 4, 5, 6, to set the foundation for the rest of the Nikon camera series.
This Nikon FM2n is an upgrade to Nikon FM and FM2 cameras and the most popular model of this series. FM2n is a full metal, fully mechanical camera. It has a battery only for the light meter and the LED that shows up in the viewfinder. Without the battery it will still work at all shutter speeds.
This camera was intended for advanced user or as a backup camera body for the professionals using either Nikon F2 or F3. The F3 in particular had an electronically controlled shutter (apart from one mechanical speed using a separate rather awkward button. So, FM cameras as a second fully mechanical camera body, using the same lenses made a lot of sense. As such it had to be just as reliable as the professional cameras and by now it is well acknowledged that it was, and still is to this day.
FM2 is as generic as SLR cameras can be, combining almost all the successful and enduring features in one reliable and foolproof package. No more and No less. Almost perfect for its purpose.
Nikon FM series of cameras came after F2 and replaced the line of Nikkormat cameras. They followed the trend of smaller and lighter SLR cameras, which was championed by Olympus and Pentax. But it is not as small or as light as those but smaller than the Nikon single digit F series. It still feels substantial, strong and very serious in the hand.
I spend a lot of time in fact checking. If you find anything that is factually inaccurate, I would greatly appreciate if you would mention it in the comments. Your personal opinions and experience of using Nikon FM2 cameras or even the close competitors will also be very helpful.
This is not a Nikon Fan channel. All 300 film cameras here are my babies. I use and review all of them without a tribal preference. But if you have a very strong preference, why not make your point in the comments, to generate interesting and respectful debates.

Why not reward hard work with a subscription. It will help promote the video on YouTube so the videos are offered to others who may also appreciate them.
