The Extender EF 2X III from Canon is designed
for select Canon EF mount L-series telephoto lenses. It increases the
focal length of a lens by a factor of 2x while still delivering superb
image quality. To ensure the best possible image quality in all shooting
conditions, it combines redesigned optics, improved data communication
between lens and camera and enhanced environmental protection. It is
ideal for photojournalists and wildlife, nature and sports photographers
who need to get close to distant and challenging subjects and it
reduces the need to carry heavy telephoto lenses.
The Extender EF
2x III features nine optical elements in five groups, ensuring improved
optical performance. All optical elements have Canon's Super Spectra
coating to reduce ghosting and flare. A new Fluorine Coating on the
front and rear elements makes marks, such as spots left by water or
fingerprints, much easier to clean than standard coatings.
facilitate the accurate transfer of imaging data between the lens and
camera body, the extender features an integrated processor which ensures
all focusing, metering and ID information is available - allowing the
photographer to capture balanced, well-exposed images. When combined
with the latest range of premium Canon L-series lenses, these extenders
enable AF accuracy even when capturing moving subjects. When attached, the 2x extender reduces the effective maximum aperture by 2 stops.
carefully positioned lens release mechanism also makes it easy to mount
the extenders quickly, reducing the time that the camera and lens are
exposed to the environment. The extenders offer the exceptional
build-quality expected from Canon's professional products, and are
resistant to both dust and water, allowing photographers to use them in
extreme shooting conditions.
