I suspect there may be problems with the Kenko 1.4 teleconverter I've been using with my D300 (died, as explained in another post) and 300 mm f2.8 AF-I lens. Now using the converter with same lens and D200 backup and getting quirky electronic behavior. Getting a D700 soon and wondering if I'd be better off with a Nikon 1.4 converter. Could the Kenko converter or even the 300mm lens be causing electronic problems in my camera?
This is frustrating and baffling.

Perhaps the contacts are dirty, either on the teleconverter or on the lens. I don't have a 300mm f2.8, but use the Kenko Pro 1.4x converter with no quirky electronic behavior with several lenses on my D300 and D50. I've heard complaints about focusing difficulties and soft images with Kenko converters, but not quirky electronic behavior.
If the lens works fine without the converter, I'd suspect dirty contacts on the converter.

I have used the Kenko x1.4 DG Pro on my old D700, D7000 and current D7100 and D800 and never had a problem. As stated perhaps a clean of the contacts may be in order.
