Canon EF 70-200mm f/4L IS USM Telephoto Zoom Lens Description
This telephoto
lens contains the most advanced IS drive
so far, producing an astonishing 4-stops of stabilization. In real life, as a
matter of fact,
it is four full stops of stabilization. No joking. For non-moving subjects, this
zoom lens becomes becomes an effective 70-200mm f/1.4 as far as handholding
capability is concerned. When there is subject movement, however, understand that f/4 is still
the actual aperture and
motion blur will be
apparent.
As for the not-as-obvious, this 70-200mm version has the
highest image quality out of any of the other 70-200mm's.
CA,
vignetting, and sharpness
are unsurpassed with this lens. Lens weight and balance is also paramount in comparison to what it offers: it's only slightly heavier than the f/4
non-IS and with all the IS advantages and not even close to as heavy as the f/2.8 IS with it's one-stop
lead.
The EF70-200mm f/4L IS USM lens
delivers the legendary sharpness and clarity of the Canon 'L' series lenses in a compact and lightweight design that is easy to use for hand held photography, making it a versatile lens for any photographer
Like all L series lenses, this one is built extremely solid. It may feel fairly large and bulky to those who haven't used L series lenses before. The extra bulk is
comes from higher quality glass and the use of more durable materials (metal vs. plastic).
Canon is the only manufacturer to provide a full range of professional zoom lenses in both the high-speed f/2.8 category as well as the compact and lightweight f/4 category. Rounding out Canon's f/4L lens lineup is the EF70-200mm f/4L IS USM lens.
This "L" series lens is designed for professional or advanced amateur photographers seeking maximum performance and versatility. This is a lens that can handle almost any assignment, ranging from distant subjects to the demanding requirements of up-close and personal
portraits as well as nature photography.
The EF70-200mm f/4L IS USM lens stands up to the rigors of professional use. The lens is sealed from dust and moisture, and is equipped with the latest generation of Canon's
Image Stabilizer (IS) technology, making it an optimal everyday shooter.
The image stabilization achieves three shutter speed steps of camera shake correction within 0.5 seconds after the shutter button is depressed halfway and yields correction for up to four full shutter speeds while handheld, providing a new level of performance. Users can also select two IS modes, one for stationary subjects and another for intentional panning.
Features
The EF70-200mm f/4L IS USM lens is the same size as the EF70-200mm f/4L USM lens that remains in the EF lens line, but the new lens adds several valuable features. In addition to enhanced weather sealing and image stabilization, the EF-70-200mm f/4L IS USM lens incorporates a circular diaphragm to create more natural looking
background blur, and distance information to aid
autofocusing and automatic flash exposure.
The lens also suppresses flare and ghosting with advanced coatings and optimal placement of its 20 lens elements in 15 groups. One Fluorite element and two UD (ultra low dispersion) elements thoroughly suppress
chromatic aberrations for crisp photos throughout the entire focal range.
v
A ring-type Ultrasonic Motor (USM) provides fast and silent autofocusing, while the full-time manual focus function provides maximum control even when the lens is set for AF.
