Actually, I looked into this when I got the 2.0 TC III - it has to do with the lens design and whether there is a "bubble" type element which will block the teleconverter from mounting. (Below from Nikon site)
The following common lenses cannot be used with an autofocus teleconverter, this is not a complete list. Please check your lens manual for a listing of incompatible accessories.
17-55 mm f/2.8G ED-IF AF-S DX 18-70 mm f/3.5-5.6G ED-IF AF-S DX 28-300 mm f/3.5-5.6 ED VR Any 18-55 mm Any 18-105 mm Any 18-135 mm Any 18-200 mm Any 55-200 mm Any 70-300 mm Any 24-120 mm Any 80-400 mm 200-400 mm f/4G IF-ED * - will only autofocus with the TC-14E II Some newer lenses can be used with older Nikon manual focus teleconverters with limited compatibility. With a manual teleconverter there would be no autofocus operation, the camera's internal exposure meter would not be active and only "Manual" exposure mode could be used. Further, there may be vignetting (darkened corners of the photo) in some photos or other image defects.
