Manual override (MO)
Manual override (MO) capable of switching two full-time manual modes* By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF.
The default setting of Full-time MF function varies for each mount.
Designed to minimize flare and ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
Nikon electromagnetic diaphragm mechanism included
The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.* Functionality may be limited on some camera bodies.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
