Sigma recently announced that the use of its Mount Converter MC-11 and certain Sigma zoom lenses with the Sony Alpha a9 (Amazon/B&H Photo/Adorama) may result in missed focus. According to Sigma USA, the issue may arise ‘occasionally’ when using AF-S mode and while shooting ‘in the telephoto range.’
