TAMRON Teleconverter 2x (Model TC-X20)
Tamron introduced two teleconverter models exclusively for select Tamron lenses. These accessories make it easy to expand the versatility of the attached lens. TELECONVERTER 1.4x increases the focal length by a factor of 1.4x, while TELECONVERTER 2.0x doubles the focal length.
Focal length: 840mm (600mm+1.4x teleconverter) Exposure: F/9 1/400 sec ISO1600
SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) with 1.4x teleconverter
Increases maximum focal length
Although the maximum focal length is increased, the minimum object distance remains nearly the same, so the magnification ratio during close focusing is enhanced. Both teleconverters are carefully designed and constructed to preserve the original superior image quality of the lens. The 2.0x model uses one LD (Low Dispersion) lens element to suppress aberrations. BBAR (Broad-Band Anti-Reflection) coatings are deployed on both models to help minimize ghosting and flare.
Easy to extend the zoom range
With a teleconverter, it’s possible to capture photographs using an extended focal length.
Autofocus and VC (Vibration Compensation) features are retained with compatible lenses
