F4.0 are much more compact.

Get yourself a set of extension tubes. They will get you closer.
Yes indeed, as Bob has suggested. I've used the shortest tube of the Pentax Extension Tube Set K on an A* 300/4, simply to get the close focus point closer (for a shot of a squirrel sunning itself on the back porch railing too close for the lens to focus on alone).
(This reminds me of another advantage of the F* 300/4.5 over the A* 300/4 - I think its close focus point is about half as close.)
