PRODUCT HIGHLIGHTS

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.

Autofocus and VC 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.

Sturdy, durable barrel design

The barrel frame of the tele converters are made of die cast aluminum, except for some parts of the exterior finish, to maintain extra strength when used with large lenses. The design utilizes a bayonet mount made of brass on the camera side and stainless steel on the lens side to ensure excellent durability even with repeated mountings and detachments.

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.
