It can't be dimmer than the E-330 and I don't find the E-330 dim at all compared to all the other DSLRs that I have used thus far and so I think the L1 would do just fine.
What Phil Askey is lamenting about is that the L1 took the risk of dimming the viewfinder and yet didn't put in a second CCD like the E-330 in its implementation of the Live View feature.
But design-wise, this camera is a dream-come-true for old-timers who still yearn for the good old days of analog controls in film SLRs. Those who have handled the LC1 would know what I mean. The LC1 is a pure work of art and a joy to use for those who appreciate the beauty and simplicity of its design. In this respect, I'm sure that the L1 will not disappoint.
I, for one, would be looking forward to owning one soon .... and it would certainly form a matching set with my LC1.
