Tamron has announced two teleconverter designed to make it easy to expand the versatility of the new SP 150-600mm f5-6.3 Di VC USD G2 ultra-telephoto zoom lens.

Tamron Teleconverters. The 1.4x and 2.0x converters.

Teleconverters mount to the body of your camera and accept a lens, increasing the original focal length of the original lens. The 1.4x teleconverter, increases focal length 1.4 times, while the 2.0x teleconverter doubles it.

Here's how each of the new teleconverters expand the focal length of the new SP 15-600mm zoom:

Full Frame APS-C Magnification
No teleconverter 150-160mm 233-930mm 1:3.9
1.4x teleconverter 210-840mm 326-1302mm 1:2.8
2.0x teleconverter 300-1200mm 465-1860mm 1:2


Highlights of the new teleconverters include:

  • Increases maximum focal length
  • Autofocus and VC features are retained with compatible lenses
  • Moisture-Proof and Dust-Resistant Construction
  • Sturdy, durable barrel design

The 1.4x teleconverter reduces the effective aperture by one f-stop while the 2.0x teleconverter reduces it by two stops.


Specifications for the teleconverters include:

Mount Canon, Nikon
Aperture Reduction One stop less
Magnification 1.4x
Optical Design 6 elements in 3 groups
Maximum Diameter 70mm Canon, 62.6mm Nikon
Dimensions 1.3 inches long
Weight 7.2 oz. Canon, 6.3 oz. Nikon

Mount Canon, Nikon
Aperture Reduction Two stops less
Magnification 2.0x
Optical Design 9 elements in 5 groups
Maximum Diameter 69.8mm Canon, 62.3mm Nikon

Tamron Announces Two Teleconverters

COMMACK, N.Y. -- Tamron, a leading manufacturer of optics for diverse applications, announces the launch of two tele converter models exclusively(1) for select Tamron lenses. These accessories make it easy to expand the versatility of the new SP 150-600mm f5-6.3 Di VC USD G2 (Model A022) ultra-telephoto zoom lens. teleconverter 1.4x (Model TC-X14) increases the focal length by a factor of 1.4x, while teleconverter 2.0x (Model TC-X20) doubles the focal length. Delivery of the new teleconverters, each available in Canon and Nikon mounts, will start on Sept. 23 in the Japanese market and soon thereafter in the U.S. market at a price of $419 for the 1.4x and $439 for the 2x.


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.

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 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.

Sturdy, durable barrel design

The barrel frame of the teleconverters 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 teleconverters feature a metal lens barrel and share this same design concept. Both teleconverters provide remarkable ease of use -- even the release lever offers a comfortable touch to the photographer's finger.
