Extending the effective focal length of the Tamron SP 150-600mm f5-6.3 Di VC USD G2 lens, this Canon EF-mount Teleconverter 2.0x renders this telephoto zoom as a 300-1200mm f/10-14 lens. The dedicated design retains communication between the lens and Canon EF-mount cameras, including auto-exposure metering and Vibration Compensation image stabilization, and both one low dispersion element and a BBAR coating has also been incorporated to maintain image quality. Additionally, this teleconverter also features a dust- and moisture-resistant construction, matching the lens, to benefit working in harsh environmental conditions.
2.0x teleconverter doubles the reach of the 150-600mm lens with only a two-stop loss in exposure.
One low dispersion element is included in the optical design to reduce chromatic aberrations and color fringing.
BBAR coating maintains image quality by reducing flare, reflections, and ghosting.
Dedicated design retains electronic communication between the lens and camera to support AE and VC functions.
When attached to the SP 150-600mm f/5-6.3 Di VC USD G2 lens, the maximum magnification will change from 1:3.9 to 1:2.
Weather-resistant design matches the construction of the 150-600mm lens itself for use in inclement conditions.
