More than meets the eye
By Nick Waters
When I ordered the product I was not aware that it was solely intended for the Sigma Telephoto lens product lines. I'm sure its a beautiful product that works in concert with the intended lens.My intention was to 2x my Sigma 18-200mm for macrophotography and was immediately discouraged upon receiving it and fiddling. However... It * does * work with the Sigma 18-200mm lens. Be aware that you must be extremely careful because you cannot fully retract the lens and "Lock" it in place.You may not be able to seat other Sigma lenses onto the 2x due to the depth of the internal condensor.
