Frank,
Thanks for the test demonstration, your E-400 looks much better than my
E-520, I think I have purchased the wrong one. The box mentioned "Live View
DSLR", I think it was designed for Live View only ;-)
For the test method, I also seen tests with newspaper but error could happen
if the sensor position is a little lower but not at the center, also if the
sensor area is too big.
