F80EXR auto focus fails more easily with low contrast than does the F70EXR

The AF should be able to lock in on some pretty minute contrast … and yet it fails sometimes where the F70EXR does not.

The upper focus point and the crease just below it with the wider shadow both give the F80EXR fits. The F70EXR seems to have little problem with this area.

The bottom focus point defeats both cameras every time.

*sigh* … the issue is somewhat inconsistent, but more prevalent in my F80EXR. Now, it is always possible that I have a bad sample, but what can I do about that? I must report what my camera does.

I don’t consider this a fatal problem, but you will probably have more issues with AF in poor light than you would with the F70EXR.
