Review of the Systems: Autofocus 3

The rules for AF3 can be found by clicking here.

Brief Summary

AF3 was an attempt to combine the best features of AF1 and AF2. To do this, it started each day with “Reverse Mode” (AF2) and “Forward Mode” (AF1) with the dismissal process of AF2.

Advantages

My own experience with using the system for a reasonable period of time was that it didn’t really offer much advantage over using either AF1 or AF2 on its own.

Disadvantages

The switching process was a bit clumsy and using AF2 dismissal  reduced some of the effectiveness of AF1.

Conclusion

This system was not an improvement over either AF1 or AF2, and has been quietly forgotten.
