Hi everyone, I am the proud owner of a 300/f4 AF-lens and I am very satisfied with it. But for some occasions I would like to have a little bit more "range" and therefore I am considering the purchase of a teleconverter. I learned already, that this lens works well with the TC-14B. But I will loose autofocus and I would like to maintain it if possible. What are my options? Is the TC-14E of any help? Are there any third-party products? I would like to hear about your opinions and experiences. Best regards and thank you for your input. Dirk
