What 45mm lens to get?

I recently bought a 645N with a manual 75mm lens and am already looking in to getting more lenses.
One that I'm interested in is the 45mm ,as I understand from the reviews on the forum the Pentax-FA 45mm F2.8 is no better than the Pentax-FA 45-85mm F4.5.
Is this true?
Does this also apply to the manual Pentax-A 45mm F2.8 or are they optical not identical?
I'm tempted by the primes because second-hand they cost about half that of the zoomlens.

Thanks.

I would still go with the prime. That zoom lens is huge!

Go with the prime. The 645 A 45 is an excellent lens.

I have the A-45mm manual focus version and it performs very well, though I find my A-35 and DFA55 to demonstrate better IQ by comparison, FWIW. The price of the A-45 was right, however, as I recall and some of my favorite pics so far have been shot using that lens.

The FA 45-85mm is excellent, esp. at 45mm, but for me it proved too heavy too big in the end. If that's not a problem for you, it appears to better than the A or FA primes at 45mm. Of course, a 45mm and 75mm together are the same weight, but not in your hand at the same time.
