Godfrey, The link seems to work, I just checked it (You need to have a PDF reader installed). But anyway, you guessed correctly. I also hadn't paid any attention to that function as I thought that AF-MF switch is already their. Today, I realized when this can be helful (to me at least). Sometimes, AF of Tamron 70-300/4-5.6 in low light with the focal length close to 300, tends to hunt and miss if the original focus position was faraway from the target. What works for me is to "preset" it manually to the right range, so that it AF quickly and more reliably. In this case the functionality of the "OK" button can help. Igor
