Before digital, before in-body stabilization, before in-lens stabilization, never ever ever shoot slower than the reciprocal of the lens focal length. 50mm on a M4/3's equals 100mm, so shoot at 1/100 sec. or faster. 18mm equals 36mm so shoot at 1/36 or faster.
Slower than that, use a tripod.Simple! Problem solved. BTW, never, ever ever shoot using the LCD held out away from the body. It is an unstable shooting platform to begin with.
LCD shooting is meant for family snap shooting or tripod. Use you EVF finder like I do.
It's a crummy finder, but you should use it only for framing your subject anyway.
I'm a satisfied GF1 user, BTW.
