It is a typo on the tittle.
21mm vs 28mm are different focal. On a pentax dslr, they result different view: 31mm vs 42mm. The numbers seem not much, but they are different.

Difficult to compare:
Pro 21: lighter, more compact, better looking (for me) , very sharp center, nice overall to use.
Con 21: Sigma zoom lenses sharper on chart tests, aspherical element is made of "plastic" as all AL lenses except the FA31. These make me feel uneasy to vote for it as "Greatest Pentax Lens".

Pro K28 f3.5: build quality, very sharp in the center of frame.
Con K28: heavy, "slow"(OK for landscape), no AF and not better then a lot of competition there at 28mm.

At the end, may be it mainly comes to compare 21 vs 28.

Interesting matchup and in saying this I note the absence of the K 28/2 from the contest (eek)

Anyway, sour grapes aside, this is a contest that will be fought on two fronts:

1. Are you an AF person or not
2. Do you travel light or not

Other differences such as FoV and FF capability also weigh in but probably to a lesser degree.

At this focal length, AF is, for me, of negligible benefit. I do not travel so, the sharpness and FF capabilities of the manual K 28/3.5 decide it for me.

K28/3.5 for me

Even owning my new-to-me FA31, K28/3.5 is my favorite lens altogether, so this is easy.

[EDIT:] But since this round is 1. vs. 8. I think I'm about to be disappointed.

I fear that we've contaminated the results by voting 21 vs 31 vs 28..

28mm correspond to the field of view of the 43 ltd on film, which is considered a normal. And 21mm corresponds to the field of view of the 31ltd on film, which is considere a wide angle.

How can they compit in the same category!?

Hmm... hard choice.

Along with the KM, KX, and K2 cameras, the SMC Pentax lenses ('K' series) introduced the venerable 'K mount' to the Pentax line. The 28/3.5 was (and still is) a highly respected wide-angle lens. I use my copy frequently, and am always happy with the resulting images. For its heritage, optical quality, robustness, and utility, it gets my nod between these two as the greatest Pentax lens of all time.

I've used both. The K28/3.5 is the better lens.
