Canon has today announced two new EF lenses; the 24 - 105 mm F4.0L IS USM and the 70 - 300 mm F4.0 - F5.6 IS USM. Of these two lenses the former will perhaps be the most interesting, promising a high quality wide zoom range in a relatively lightweight package and image stabilization it clearly lends it self to be the perfect partner lens for the new EOS 5D. Indeed in their press release Canon state that this new lens 'offers a lightweight alternative to the renowned EF 24-70 mm F2.8L USM'.

Canon’s lightweight, Image Stabilizer zoom lens for professionals
Amstelveen, The Netherlands, 22 August, 2005: Canon, a leader in photographic and imaging technology, today announces the launch of its latest professional L-series lens: the lightweight EF 24-105mm f/4L IS USM with Image Stabilizer. Dust and moisture resistant and incorporating Canon’s very finest standards of precision optics, the EF 24-105mm f/4L IS USM is designed for reportage, event, travel and celebrity photographers looking for a lightweight and manoeuvrable lens with minimal image quality compromise.
Complementing the EF 17-40mm f/4L USM and EF 70-200mm f/4L USM, the lens completes Canon’s f/4L-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 flagship professional lens range, designed to include outstanding image performance, ultimate operability and weather resistance. The EF 24-105mm f/4L IS USM offers a lightweight alternative to the renowned EF 24-70mm f/2.8L USM.
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 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions.
The ring-type USM motor found in the EF 24-105mm f/4L IS USM employs ultra-sonic frequency vibrations to drive auto focus 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 auto focus mode.
Constant f/4 aperture from 24 to 105mm
The EF 24-105mm f/4L 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 f/2.8L USM counterpart. The lens employs an almost perfectly circular barrel aperture, helping create attractive, defocused backgrounds.
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 colour fringing. Aspherical lens elements correct spherical aberration for crisp, high contrast corner-to-corner quality. By optimising 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 colour balance.
EOS system integration
The EF 24-105mm f/4L 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 and EOS 5D . 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 mount 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 f/4L IS USM comes with a bayonet mount 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.

Canon’s new telephoto zoom lens with Image Stabilizer
Amstelveen, The Netherlands, 22 August, 2005: Canon, a leader in photographic and imaging technology, today releases the EF 70-300mm f/4-5.6 IS USM zoom lens. Featuring the latest 3-stop Image Stabilizer for outstanding camera shake reduction, the lens also features super responsive auto focus. Replacing the popular EF 75-300mm f/4-5.6 IS USM, the world’s first interchangeable lens with Image Stabilizer (IS), the lens is expected to appeal to serious amateur nature and sports photographers looking to achieve outstanding results while shooting hand held.
IS dramatically reduces image blur caused by camera shake. The EF 70-300mm f/4-5.6 IS USM features Canon’s latest 3-stop IS, a one-stop improvement over its predecessor. This allows shutter speeds up to three stops slower than would otherwise be possible, with no perceptible increase in image blur. Photographers normally shooting a 300mm frame handheld at 1/500s can obtain the equivalent result with a shutter speed of just 1/60s, vastly extending options in low light conditions.
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 EF 70-300mm f/4-5.6 IS USM provides 2-mode IS for shooting immobile subjects. Mode 1 stabilizes the image along both the horizontal and vertical axes. For shooting while panning to follow a moving subject, Mode 2 turns off correction in the panned direction and prevents the effect of dragging the subject back through the frame. IS switches off automatically when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations.
The micro USM motor found in the EF 70-300mm f/4-5.6 IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. A high speed CPU and optimised AF algorithm result in a significant increase of AF speed compared to that of its predecessor.
A zoom ring locking mechanism is provided that locks the zoom at the wide-angle setting. This ensures that the lens is carried or stored in its most compact position, preventing possible damage caused by the lens extending and hitting obstacles when being carried mounted on a camera with a strap.
Pleasing defocused background
The EF 70-300mm f/4-5.6 IS USM employs an electro magnetic diaphragm (EMD) with a circular aperture. This helps create an attractive, even defocused background when isolating a subject at large apertures.
By optimising 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 colour balance.
