Not sure how to add this for it to be efficient, but I think I can leave the code here for people to use (I'm sure some action sidescrolling games could benefit from it)

(untested with rotation - and I expect it to not work with it yet anyway)

public var targetsBounds:Rectangle = new Rectangle();
public var targetsCenter:Point = new Point();
public var targets:Vector.<Object> = new Vector.<Object>();

//init
camera.target = targetsCenter;

//update

var o:Object;
var left:Number;
var right:Number;
var top:Number;
var bottom:Number;

for each (o in targets)
{
    if (!left || o.x < left)
        left = o.x;
    if (!top || o.y < top)
        top = o.y;
    if (!right || o.x > right)
        right = o.x;
    if (!bottom || o.y > bottom)
        bottom = o.y;
}

targetsBounds.setTo(left, top, right - left, bottom - top);
targetsCenter.setTo(targetsBounds.left + targetsBounds.width * .5, targetsBounds.top + targetsBounds.height * .5);
//fit all targets on screen - TODO: add margins
camera.zoomFit(targetsBounds.width, targetsBounds.height);
