I have a 1.4E Nikon Teleconverter which I have owned for the past 12 years or so. I just received my new Nikon 200 - 500 mm f/5.6 lens and as I was testing this lens I decided to try it with the teleconverter and I found it does quite a little hunting for focus, which it does not do without it attached. I have noticed that I have a little hunting when it is attached to my Nikon f/4 600mm. I am wondering if the new versions of the teleconverter such as the Nikon 1.4 XE III would be an improvement over the one I have. These, as you know, are an expensive item and I don't want to purchase one without some assurance that it will solve the problem. Any opinions would be greatly appreciated.
