Does the Xs 10 have the Dual Iso at 640 and 2000? I can't see the difference in noise reduction when it comes to 2000 and Im wondering is it a defect of the camera or is there a setting that I've to turn on. That's if the Xs 10 even supports it in the first place. I'll be thankfull for any feedback because I've been racking my brains trying to work it out. Thanks
