Tamron introduced two tele converter models exclusively for select Tamron lenses: SP 70-200mm F/2.8 Di VC USD G2, and SP 150-600mm F/5-6.3 Di VC USD G2 & 100-400mm F/4.5-6.3 Di VC USD.
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
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.
Design concept
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 tele converters feature a metal lens barrel and share this same design concept. Both tele converters provide remarkable ease of use—even the release lever offers a comfortable touch to the photographer’s finger.
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 converter
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.
Focal length: 840mm (600mm +1.4x tele converter) Exposure: F/9 1/400 sec ISO 1600 SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022) with 1.4x tele converter
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-X14 tele converter reduces the effective aperture by one f/stop.
