Sigma 2x EX DG Tele Converter

The Sigma 2x EX DG Tele Converter review is planned.

Great photos... Really enhances the lens.

No problems yet.

this teleconverter is perfect with a sigma 70-200 DG excelent value for money! You will get extremely sharp images if you get few steps forward closer to lock on your subject that is distant let's say 30 meters... On other shots the quality is good for...
