The link seems to work, I just checked it
(You need to have a PDF reader installed).
But anyway, you guessed correctly.
Ah, it does work, it just has some odd notion of wanting me to choose
Adobe PDF Reader application first. Weird. I have the manual
downloaded and on my disk already, however (also the ones for the D
and DL).
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.
Interesting. When the light gets down to the point where the AF hunts
too much, I just switch to MF and do the focusing myself. Different
way of working, I guess.
