Teleconverters Models TC-X14 & TC-X20
1.4x (Model TC-X14) & 2.0x (Model TC-X20)
Tamron’s two teleconverter models are exclusively for selected Tamron lenses. These accessories make it easy to expand the versatility of the attached lens. Teleconverter TC-X14 increases the focal length by a factor of 1.4x, while the Teleconverter TC-X20 doubles the focal length.
Key Features
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.
Focal length: 900mm (450mm+2.0x teleconverter)
SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) with 2.0x teleconverter
Exposure: F/13 1/1000sec ISO500
Easy to extend the zoom range
With a teleconverter, it’s possible to capture photographs using an extended focal length.
Autofocus and Vibration Compensation features are retained with compatible lenses
Autofocus functions normally with compatible lenses and VC (Vibration Compensation) performance is maintained.
