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 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.
Easy to extend the zoom range
With a tele converter, it’s possible to capture photographs using an extended focal length.
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.

* Use of the TC-X20 tele converter reduces the effective aperture by two f/stops.
** Length is the distance measured from the camera mount face to the lens mount face.
*** Entire Length is the distance between the tip of the lens and the tip of protrusion.

*(1) Autofocus functions normally on any camera that offers F/8 autofocusing. (see your camera’s instruction manual for your camer’s ability).
*(2) Subjects with low contrast and/or luminosity values can sometimes result in out-of-focus images.
