I got this lens just prior to my family's new year's party. I wanted a wider angle companion to my FA 43 for indoor shots and wanted it to be small for easy switching.
Overall I am very happy with the results. Both the 43 and 21 has magical rendition. the 21's shows up less frequently than the 43. I just have to learn to use it properly to get more of the magical rendering with the 21, but it's definitely there.
Both sharpen very easy with PS (unsharp and smart sharp) more than my 18-250.
If there was a shot that was bad, then it was mostly because of bad technique with the exposure and flash, and not because of the lens. The IQ looked close from both the 43 and 21, and that's saying a lot about the 21. Of course the 21 cannot do what the 43 can at f2.2 close up's, or full face shots at F5.6, but for group shots it is close to the 43. Then again, with the 21, it feels like you are there inside the room as opposed to a high IQ image. The images pop and due to wideangle it feels like being there.
Also, one gets spoiled by these lenses and forget how good they are. I got used to the 43 and first I thought the images weren't as good as I was getting when I first switched from the 18-250 to 43. I compared thses to the previous ones to realize the images are still as good as before, but I've gotten used to the superb quality and I am taking them for regular shots now.
Using the flash (Pentax 540) and getting the exposure right with my K10D was the biggest challenge.
I would say that 50% of my images can be gotten from most zooms, mostly due to the technique being sub par (I think), 20% not too good (technique or the image itself), 30% the 18-250 cannot even imagine producing.
Bot the 21 and 43 are small enough to be kept in my trouser pocket, and I was easily able to switch between the two. So, the DA21 and FA43 are excellent pairs, and I am very pleased with them. The 18-250 will shortly go on the market, interested parties keep an eye out for it.
P.S: Sorry no images, as I don't like to put family shots on the web.
