Well, this is disappointing! As some of you know, I picked up my first mirrorless system last week- an E-M5. I was just doing some ISO tests then to get an idea of how much noise to expect at different settings and I'm noticing a bright pink dot in every photo I take. It's small enough that I never noticed it until doing these tests, so maybe it's not even an issue, but it's certainly there. I've tried numerous focal lengths, apertures and ISO settings, even shooting with the lens cap on and it's there in all of them (though the shutter does need to be slow enough to let some light in, in this case). I figure I should take it back to where I bought it from?
