KC, 
 
The lens hookup is as good as the body itself.  I mean its just like attaching the lens to the body as the lens side of the teleconvertor has an identical mount as the body.  A 200mm lens will be 400mm at 2X so your minimum shutter speed should also double. 
 
The biggest consideration of any teleconvertor is the light loss a 2X TC (teleconvertor) will lose 2 f-stops because it is creating a much larger light circle in the camera.  On a sunny day it should not be a problem. 
 
I have a 1.7X TC on a 200-400VR lens and at 400mm on a monopod I cannot keep the image still so I need real fast shutter speeds such as 1/2000 as a precaution against blur.
