When you use a Teleconverter you gain in the reach of the lens BUT what do you loose? Well usually you suffer in sharpness and you may find that you lens hunts more when trying to focus, for starters. I found this video that has some pretty good side by side comparisons as to sharpness when using the 1.4x and 2.0x teleconverters.
Oh by the way, Teleconverters are also often known as Extenders (for the Canon shooters among us.) and yes they are exactly the same thing.
