[QUOTE="Horoscope Fish, post: 647248, member: 13090"] It's a known issue with that particular lens/body combination. To my knowledge there is no known fix, workaround or solution. According to Sigma: [I]"This behavior is related to the operation of the OS unit of the lens when it is used in conjunction with the Nikon D7100.
