ASP, HSM, IF, EX

ASP (Aspherical Lens)

The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

HSM (Hyper-Sonic Motor)
This lens uses a motor driven by ultrasonic waves to provide a quiet, highspeed AF.

IF (Inner Focus)
To ensure stability in focusing, this lens moves the inner lens group or groups without changing the lens' physical length.

EX (EX Lens)
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
