The Panasonic cameras have the ability to "re-calibrate" the sensor, meaning you run a special routine and it identified hot pixels (quickly saturated) and maps them out. Does the Oly have the same thing somewhere?

I notice some marginal improvement on my G1 depending on temperature. The warmer the cam, the more hot-pixels I wind up with. If I re-calibrate while it is relatively hot, I get pretty good results later on.

Not that I have has much opportunity to take lightning pics this year. Storms have been skirting by leaving my location very dry.

Yeah, it does have hot pixel mapout, but it does not help with hot pixels that you start to see on really long exposures like this. It is the same way on the Panasonics, I used to have one.
