HSM
The hypersonic motor built into the lens uses hypersonic waves to function quietly while providing a high-speed autofocus. This motor can also be used to manually adjust focus and capture pin sharp details.

IF
This lens focuses internally as the inner lens adjusts without the outer lens physically changing length.

TSC
The physical barrel of the lens is manufactured from a Thermally Stable Composite material, resisting temperature changes in various climates.
