What does DG HSM mean?

DG means it is designed with full-frame cameras in mind, so can be used on such bodies as Nikon D800 or Canon 5D Mark III (obviously you need an appropriate mount version for either system). The lens has Sigma’s ring-type ultrasonic autofocus motor (HSM) and optical image stabilization (OS)..

What is an HSM lens?

For those unfamiliar with the numerous lens acronyms, HSM stands for Hyper Sonic Motor, (also known as Ultrasonic motor, Silent Wave Motor or even Sonic Direct-drive Motor) and is a faster, quieter and often more compact motor system for lenses.

What does Sigma HSM mean?

The Hyper Sonic Motor (HSM) is an original SIGMA development that uses ultrasonic waves to drive the autofocus mechanism. Its extremely quiet operation helps avoid disturbing photographic subjects. High torque and speed assure rapid autofocus response. SIGMA uses two types of HSM: ring HSM and micro HSM.

What is a HSM used for?

A hardware security module (HSM) is a physical device that provides extra security for sensitive data. This type of device is used to provision cryptographic keys for critical functions such as encryption, decryption and authentication for the use of applications, identities and databases.

What makes an HSM secure?

HSMs provide both logical and physical protection of these materials, including cryptographic keys, from disclosure, non-authorized use, and potential adversaries. HSMs support both symmetric and asymmetric (public-key) cryptography.
