Mark II Technology

Mark II Technology works by having additional data tailored for your lens, resulting in the highest performance possible with a lens mount adapter. Lens profile data of the following lenses are stored in your Speed Booster or Smart Adapter. The LED turns pink to indicate that a matching lens profile is found and Mark II technology is operational.
