Tamron introduced two tele converter models exclusively for select Tamron lenses. These accessories make it easy to expand the versatility of the attached lens. TELE CONVERTER 1.4x increases the focal length by a factor of 1.4x, while TELE CONVERTER 2.0x doubles the focal length
Increases maximum focal length
Focal length: 900mm (450mm+2.0x tele converter) Exposure: F/13 1/1000sec ISO500
SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) with 2.0x tele converterAlthough the maximum focal length is increased, the minimum object distance remains nearly the same, so the magnification ratio during close focusing is enhanced. Both tele converters 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.
Autofocus and VC (Vibration Compensation) features are retained with compatible lenses
Autofocus functions normally with compatible lenses. (Please refer to Compatible Tamron Lens List below.) VC (Vibration Compensation) performance is maintained.
Moisture-Proof and Dust-Resistant Construction
The new tele converters are ideal for use in outdoor photography when matched with any lens that has a Moisture-Resistant Construction because special seals that are dust-resistant and moisture-proof are used at every joint and seam.
