FE was aimed at the amateur market, although I'm sure some pros had it as a backup to their F, F2, F3, etc.

As I recall, much was made about the FE's battery dependency. It had just two manual speeds if the batteries died: 1/90 and B.

I believe the all manual FM was the backup camera of choice for pros. The batteries powered only the meter.

Again, I wouldn't base any purchasing decision of whether a camera was for pros or amateurs.

In fact, a specific camera won't make you a better photographer, although that's always the promise.

However, you will feel more comfortable using certain cameras, and it's then that you'll take "better" photos.
