Whenever I read about high ISO performance expectations some people have, and it gets me thinking "should I switch to Canon or Nikon?", I reminisce about the days when pushing Tri-X or EK400 to 800 or (gasp) 1600 was rife with issues regarding grain, muddy shadows, blocky hilights and in the case of EK400, color shifts (of course, pushing it for use in a concert, the color shift was secondary since people expected multicolored lights during most concerts, or were willing to deal with the warm cast under standard lighting).
I do want to take advantage of the best performance I can get at any given ISO. But my personal "photographic reality" is that ISO 1000 to 1600 is a marvelous revelation after years of film, and the E5 performs quite well in that range. I'm receiving more offers to do concert and performance photography, so I am giving serious though to what my kit should be for that venue. Right now as I ruminate over adding a Canon 60D, Nikon D7000 or even a Pentax K5 kit, I compare the other aspects I like about Olympus and I'm still of the mind that an E5 will serve me quite well.
It's interesting that given the way some folks talk about hi ISO performance being the defining aspect You'd think low light photography simply didn't exist prior to digital LOL. I think many of those demanding noise free ISO 3200 or 6400 should be using flash: at least from the photos I've seen them display taken at high ISO.
