I bought mine as my first Nikon, while i was primarily using Canons. I just always liked Nikon film bodies, and wanted to 'dabble' a bit. Since then, i've had a string of Nikons: F100, F6, back to F100, F80, F4, FG (broken), EM (broken), and most recently an F3. Of all of those cameras, i kept only the FE2 the entire time, and went back and forth with the F100 (I still have it). The F3 is something i've only had for two months or so.
I like so much about the FE2, but the three 'flaws'/characteristics i don't like are what keep it from being the perfect manual film SLR.
• There's no On/Off switch. You activate the meter by pulling the wind lever out a bit. That may seem to be a trivial matter, but i've never gotten used to it and it still feels silly. When i'm walking around with it, i just expect to be able to raise it to my eye and meter/shoot. I'm caught out too often by that damn lever.
• The meter. I don't really like a needle. Seems like i can't see the numbers on too many occasions. I'd prefer an LED or the F3's LCD.
• No AE lock with a half-press of the shutter release. Instead, it's a separate switch, on the front of the body. I'll never use it there. It should have been on the shutter button, or the later Nikon compromise, the button on the back panel, just below the top deck.
Other than that.... It's a gorgeous, well-built, solid, small camera, with a very nice finder and satisfying shutter/mirror sound and wind advance.
Now that i have the F3, i'm a bit more taken by the F3, but that's probably just a honeymoon effect. The F3 is a bit larger than i'd like, but the larger finder is what i'm into now. If i had to choose one of them, i'm not sure what i'd do. Good thing they're all so cheap these days, right?
To be honest, if i wanted to spend the money on an FM3a, i'd probably be happiest with that, versus the FE2 or F3, but it's a considerable amount more, and because i use so many different cameras (all too infrequently, though), i couldn't justify it.
Which Nikon/s do you currently have? If you already have an F3, unless you want a slightly smaller/lighter camera, i don't think you really need to make a switch.
