Thanks for the new .bin file! You are very fast.
Yes, you're right. Today, i was at a private poolparty. I shot with your actual .bin file to test it.
I could reproduce the error, when i changed the ISO blind and fast.
But i had another problem: Sometimes, i get the "Error99". I would say, every 20-30 picture (RAW+L) couldn't be saved, because there was an Error99...
