SLR shooters have been dealing with autofocus misalignment issues for as long as autofocus itself has existed, but thanks to Nikon’s new AF Fine Tune feature, what used to be a very annoying and difficult problem can now be fixed with a few button clicks.
As you might already know, front- and back-focus issues are something experienced exclusively by SLR shooters, since mirrorless cameras draw their focus straight from the image sensor.
