FA 28-105 question

Does the barrel extend on the Pentax smc FA 28-105 f/3.2-4.5?

It's going for $210 new at Adorama, but it doesn't have the [IF] designation. What does IF mean in this instance?

Thanks for any info,
FHPhotographer

[IF] means internal focus, doesn't move when focusing
most zooms of this type will extend when zooming
