TAMRON TELECONVERTER X1.4 CANON
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.
Moisture-Proof and Dust-Resistant Construction
The new teleconverters 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.
These accessories embody Tamron's new design that's born from the pursuit of functional beauty and achieved by smoothly blending engineering and design enhancements. Meticulous craftsmanship is applied to every detail. The new teleconverters feature a metal lens barrel and share this same design concept. Both teleconverters provide remarkable ease of use Ñeven the release lever offers a comfortable touch to the photographer's finger.
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.)
