Description
The Canon 2x III extender extends the focal length 2 X of any compatible Canon telephoto. While supporting full electronic functionality when used with a compatible EOS camera body. With a multiplication of focal length by 2x, at a cost of two stops. For example, an f/2.8 lens will become an f/5.6.
Previous extenders led to a significant loss in image quality. For example, overall sharpness. However, the new mark III version of the Canon 2x teleconverter has minimal quality loss. Also, use the 2x Extender with existing telephotos lenses. Instead of requiring much larger, more expensive telephoto lenses.
We recommend using this extender with f/2.8 aperture or greater lenses. Slower lenses become limited by the loss of light. Typically, the more light coming through the lens, the better your auto-focus performance will be. Most cameras lose auto-focus with a lens slower than f/5.6. However, a notable exception is the professional grade 1D series cameras. These can auto-focus to f/8.
The 2X extender combines new optics with improved data communication between lens and camera. In addition, enhanced environmental protection. This makes it ideal for photojournalists , wildlife, nature and sports photographers. Reducing the need to carry heavy telephoto lenses.
A 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.
Note: This converter is only compatible with fixed focal length L-series lenses 135mm and over. In addition, Canon 70-200/2.8L IS mark III, 300mm f/2.8L IS and EF 100-400/4.5-5.6L. Additionally, please see the lens and/or camera body manual for full compatibility information.
- Finally, the Canon 2x Teleconverter is sealed to be resistant to both dust and water. This allows photographers to use them in extreme shooting conditions.
