Newly designed HSM for nimble AF control

The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance, and the updated AF algorithm helps ensure nimble autofocus performance. In addition, full-time manual focus override allows the lens to be switched to manual focus simply by rotating the focus ring—even during continuous AF. The user can quickly find the perfect focus without needing to touch the focus mode switch.

Mount with dust- and splash-proof construction

The lens mount incorporates rubber sealing to protect the mount from dust and water drops.

Nikon electromagnetic diaphragm mechanism included

The lens for the Nikon camera includes the electromagnetic diaphragm mechanism and is able to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

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.

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

A design that prioritizes optical performance—without compromise.

Outstanding resolving power and minimized chromatic aberrations help make this the ultimate lens for portraits.

To create a top-performing 85mm F1.4 lens, SIGMA leveraged its latest innovations in design and materials. The result is the ultimate lens for portraits.
