166 The “Recording” (Camera icon) Menu Settings

purposes, but I personally believe it was a farce to make people think they
were actually being heard. One of the questions was, “Which do you
prefer? 1) Fast Autofocus 2) Accurate Autofocus.” (And there was no
selection for “All of the above”). That’s when I realized that there might be
an engineering tradeoff at play here.
Fast forward about 9 years and we can see that there must not have been an
overwhelming consensus about which of the two choices people wanted,
for the A77 II (plus many cameras before it) gives us this very choice: You
can have it fast, or you can have it right, but you can’t necessarily have
both.
Here’s an educated guess as to what’s going on: the “fast” option will take
a reading, spin the focusing the right place, and then quit. (It’s a computer.
It probably got it right.  ) The “slow” option will do the same thing but
then take another reading to verify that the proper focus was achieved
before giving the focus confirmation signal. After much experimentation
I’ve determined that I can’t see or notice any real-world difference between
“Fast” and “Slow” on any of my lenses – both settings seem to result in
identical focusing times and identically-sharp images.
Are there any older, special-purposes lenses would benefit from the “slow”
setting? I initially thought that lenses which had a low screwdriver-blade-
to-turn ratio, like my old Minolta 50mm macro lens, would be more
accurate in “slow” mode, but it turns out that all lenses in my collection,
old and new, work perfectly well on “Fast”.
My recommendation: Since it doesn’t seem to matter, use the slow setting,
just in case.
