Usually when I shoot multiple pictures they are all exposed similarly, but
occasionally the first one will be darker. It's generally after the camera has
been sitting for a while, but I'm not sure how long of a pause it requires.
On, or asleep?
One other bit of data: If I turn the camera on and immediately take a picture,
it sounds like a picture has been taken, but the resulting image is entirely
black. If I count to three or four before taking a picture it comes out ok.
Is there not a short delay while the sensor cleaning happens whenever the camera is turned on? Also when it is awakened?
I never had a 4/3 camera, so I don't know the details.
IF cleaning were in process when the shutter release was pressed, AND a firmware glitch allowed an image to be recorded,
even though the sensor is busy and unavailable and buffer empty, that could result in a blank frame.
I just had a quite odd exposure glitch in the E-M5 II, and the Oly support tech agreed it was bizarre and hard to
imagine what would cause it. After checking a few things per his email instructions, I followed his advice and tried a
full reset. Annoying, as I had to note on printouts of manual pages all my settings, then reset them all. BUT, the
inexplicable oddity went away. Sometimes, cosmic rays flip a bit ...
Judging from what I'm hearing, I'm leaning toward a camera fault.
I am too, but only leaning, not sure, something sticky/slow in the shutter mechanism. First curtain delayed, second on
time, would result in a darker image, and that action has loosened it up for the second shot. For a completely blank
frame, though, the first curtain would have to delay opening until the second had already closed. I suppose if there's
something that warms up when the body is on right near the shutter, that might give such results when turned on from cold.
But before acting on that assumption, I'd try a firmware reset.
That is made worse by operator faults.
Doesn't sound like you are doing anything wrong.
