Andy Bright's review

A handy teleconverter that does make a considerable focal length difference on long lenses compared to the 1.4x teleconverter with just half an f stop extra. Nikon's TC-20E 2x teleconverter is often too much and doesn't have such a wonderful reputation compared to its smaller siblings.

In use it is difficult to spot if this teleconverter introduces any optical problems of it's own, as use on very long lenses will likely introduce factors such as atmospheric pollution and instability into the equation.

In ideal circumstances this teleconverter is a remarkable performer, optically close to the TC-14E.

Build quality is excellent.

Pros

  • Useful magnification factor
  • build
  • optical clarity
