Product description

Aperture Range: f/1.4-16

With a bright maximum aperture of f/1.4 this lens allows you to capture images with beautiful defocused background bokeh effects in darker conditions - using faster shutter speeds and lower ISO sensitivities.

Hyper Sonic Motor (HSM)

This lens' motor is driven by ultrasonic waves to provide quiet, high speed autofocus. This Hyper Sonic Motor (HSM) ensures high speed and quiet AF as well as full-time manual focus override by rotating the focus ring.

Floating Internal Focus System

For stable focusing, this lens moves its inner lens groups without changing the lens length. It also compensates for astigmatic aberration and provides extremely high optical performance for close-up photos.

Minimum Focusing Distance: 11.8"

This lens has a minimum focusing distance of 11.8" so you can capture wide-angle close-ups from nearly a foot away.
