Clarification: Penalty dice for Auto-Fire

[pwiecek 0]

My SMG skill is 80%. I can fire 8 rounds in a volley. If I split the damage of the volley among 4 opponents all within my normal range, I have to make an additional roll every time I switch targets. Do these additional rolls incur penalty dice? Or do penalty dice accrue only when I fire multiple volleys?

In addition:

This costs me 11 rounds

Each opponent is hit by one bullet

As I read the rules, yes, you add penalty dice (or remove bonus dice, or raise the difficulty level) for each new attack roll, not just for each new volley. Hence the "First attack roll" and "Second and further attack rolls" headings in the "Rolling to hit with automatic fire" section starting on p. 114 of the Keeper's Rulebook.
