The Canon EF-mount 1.4x teleconverter extends the focal length of selected Tamron lenses, allowing greater reach for telephoto lenses. The special design maintains full communication between the lens and Canon EF-mount cameras, including automatic exposure measurement, autofocus at selected focal lengths, and Vibration Compensation image stabilization. Additionally, a BBAR coating has been applied to reduce reflection and distortion, preserving image quality.

The teleconverter also features a dust and moisture-resistant construction, suitable for working in challenging environmental conditions.
