On the E-1, there are two settings that allow manual focusing.  There is a 
three-position, mechanical switch for this: MF, S-AF, C-AF.  The switch is 
located (as you look at the camera from the lens), at about the 5:00 position 
on the body.

1. MF - the manual focus ring is the only way to focus the camera.  It's 
focus-by-wire, so you can cofigure the ring to turn in either direction, 
depending on what camera system you learned on.  e.g., I learned on OM and 
Leica-M systems, both of which turn to the left to focus closer, Nikon is the 
opposite.  It's got a nice feel and is very, very close to a real, MF lens.

2. S-AF - (You must have the "S-AF+MF" option set, or MF is inactive). Press 
the shutter release half-way down for the AF to lock on, and hold it.  Then the 
MF ring becomes active and you can tweak the focus, then continue to press the 
shutter release, completing the exposure.

3. C-AF - the MF ring is inactive, in all modes

The MF ring doesn't turn ever unless you turn it; AF operation doesn't move the 
external ring.

You can also configure the AEL button to operate the autofocus in S-AF mode, 
independent of the other switches.  I'm not sure if the AEL button will operate 
the autofocus system in MF mode, I can't remember, and I'm not with my 
camera....I don't think so.
