While I do agree that the user should have the option of pulling
the histogram up easier, it is not such a huge problem imo. I have
only had an E-1 a short time, so I am not totally used to the
cameras metering, but in time I think most users get to a point
where they know their camera well enough to make educated metering
guesses and not be pulling the histogram up for every shot.
I find I enjoy the noise at iso 100-800 as it adds a nice texture
similar to film. 1600 is not really bad either imo. 3200 I am
still deciding about simply because of the banding. I would use
them all freely however, but I am of the belief that a great image
is great regardless of noise. I think you shoot an image with the
iso characteristics in mind and work with that. The E-1 has not
really limited me at all in any reasonable shooting situation and I
shoot in seriously low light at times.
