- Carefully positioned lens release mechanism makes it easy to mount the extender quickly, reducing the time the camera and lens are exposed to the environment.
- Integrated processor communicates between camera and lens and ensures all focusing, metering and ID information is available.
- All optical elements use Canon's Super Spectra coating, reducing ghosting and flare.
- Fluorine Coating on the front and rear elements keeps soiling, smears, and fingerprints to a minimum.
- Sealed to be resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.
