When your lenses aren't focusing as well as they could be.

Hi,

That's correct, but only if there is a systematic bias towards front or back-focusing every time. AF fine tuning works great for removing the bias, but there will always be some inaccuracy left depending on the AF system and lens.

Cheers,
Bart
