Overview: The Canon EF 24-105mm f/3.5-5.6 IS STM lens is a
standard zoom lens, designed for Canon EOS full-frame cameras. The lens
features an image stabilizer to help prevent blurred images caused by camera
shake. The inner focusing system and STM
(stepping motor) gives you smooth, quiet auto focusing.
Stepping Motor (STM): The lens features a lead screw-type stepping motor in
the focus mechanism. The inner focus lens, and stepping motor support the Canon
EOS Movie Servo AF function, to provide smooth and quiet auto focusing during
video recording, as well as when shooting photos.
Note: When the camera is off or in the sleep mode, the
motor does not operate and manual focusing is not possible.
Focus Mode Switch: You can switch between Auto Focus and
Manual Focus using the two-way AF/MF switch on the barrel of the lens.
Focusing Ring: Regardless of whether you're in manual or
auto focus mode, the full-time manual focusing ring always works. This means you can
auto focus on a subject, but manually change the focus, if needed, by turning the focusing
Image Stabilizer: The built-in Image Stabilizer provides
superb correction for camera shake that it is equivalent to a shutter speed 4
stops faster, even in dim light. The Image Stabilizer begins to work when you
press the shutter button halfway. If you are placing the camera on a tripod, it
is recommended that the Image Stabilizer be turned off.
Locking Zoom Ring: The zoom ring can be locked to keep the
lens at its shortest point, preventing the lens from extending. This is
convenient when carrying the camera on a strap with the lens aimed downward.
Circular Aperture: The lens has a 7-blade circular aperture
that delivers beautiful soft-focus backgrounds.
Optional Accessories: The lens has a 77mm mounting thread on the
front of lens for attaching screw-on type filters. In addition, the optional
EW-83M lens hood is available to prevent stray light from entering the lens and
causing unwanted glare.
