From the Manufacturer
---------------------
Dust and moisture resistant and incorporating Canon's very
finest standards of precision optics, the EF 24-105mm f4L IS USM
is designed for reportage, event, travel, and celebrity
photographers looking for a lightweight and maneuverable lens
with minimal image quality compromise.
Complementing the EF 17-40mm f4L USM (
exec/obidos/ASIN/B00009R6WO/${0} ) and EF 70-200mm f4L USM (
exec/obidos/ASIN/B000053HH5/${0} ), the lens completes Canon's
f4L-series zoom lens range. These lenses are designed for
professional photographers requiring a light zoom lens with a
fixed aperture throughout the zoom range. For outstanding
camera-shake reduction, Image Stabilizer allows shutter speeds of
3 stops slower than would otherwise be possible, with no
perceptible increase in image blur.
The L-series is Canon's ship professional lens range,
designed to include outstanding image performance, ultimate
operability, and weather resistance. The EF 24-105mm f4L IS USM
offers a lightweight alternative to the renowned EF 24-70mm f2.8L
USM ( exec/obidos/ASIN/B00009R6WT/${0} ).
Image Stabilizer
Image Stabilizer (IS) dramatically reduces image blur caused by
camera shake. Gyro sensors detect unwanted vibrations, triggering
the corresponding movement of a correcting lens group
perpendicular to the optical axis. This alters the light path,
returning the image to its correct position on the sensor or film
plane.
The 3-stop advantage means that photographers normally shooting a
105mm lens handheld at 1/125 second can obtain a shake free
result with a shutter speed as low as 1/15 second, for vastly
extended options in low light conditions.
Superb autofocus
The ring-type USM motor found in the EF 24-105mm f4L IS USM
employs ultra-sonic frequency vibrations to drive autofocus with
unrivalled speed and near-silent operation. A powerful CPU and
improved AF algorithm contribute to speed performance. Good
holding torque stops the lens with precision and accuracy, the
instant it arrives at the correct focus point and without
overshoot. Photographers can choose manual focus instantly and at
any time simply by moving the manual focus ring without first
having to switch out of autofocus mode.
Constant f4 aperture from 24 to 105mm
The EF 24-105mm f4L IS USM offers the highest possible optical
quality with no change in aperture over the full focal range of
the lens. This allows photographers to set exposure at the widest
aperture and zoom all the way through to 105mm without having to
vary the shutter speed. It is the perfect lens for professional
photographers looking for a lightweight and extended zoom
alternative to its EF 24-70mm f2.8L USM counterpart. The lens
employs an almost perfectly circular barrel aperture, helping
create attractive, defocused backgrounds.
Image quality
To limit lens size and improve image clarity over the total
image area, an Ultra-Low Dispersion glass (UD) element is used to
eliminate the secondary chromatic aberrations that otherwise
reduce sharpness and introduce color fringing. Aspherical lens
elements correct spherical aberration for crisp, high-contrast,
corner-to-corner quality. By optimizing Super Spectra lens
coatings and lens element shaping, Canon's engineers have been
effective in suppressing flare and ghosting--more prone to occur
with digital cameras due to reflection off the image sensor. By
increasing light absorption, coatings reduce reflections off lens
element surfaces to deliver crisp, undistorted images with
natural color balance.
EOS system integration
The EF 24-105mm f4L IS USM includes distance metering
information, providing compatibility with the E-TTL II flash
system of late-model cameras such as the EOS-1D Mark II N (
exec/obidos/ASIN/B0007Y793K/${0} ) and EOS 5D (
exec/obidos/ASIN/B0007Y791C/${0} ). When used in conjunction with
Canon's range of EX Speedlite flash units, the lens passes
distance information to the flash algorithm for markedly improved
flash exposure metering. To match the weather resistance afforded
by EOS-1 professional camera bodies, an O-ring seals the lens
against the lens and numerous seals around the lens' moving
components provide protection against the ingress of dust and
moisture.
AF Mode and IS switches have been reshaped, making them less
susceptible to being engaged or disengaged accidentally.
The EF 24-105mm f4L IS USM comes with a bayonet lens hood
EW-83H and soft lens pouch LP1219. In keeping with Canon's Kyosei
philosophy of living in harmony with the environment, the lens
features only lead-free glass.
