Which new lenses for my Pentax K10D?

I thought it was about time I tried a post of this kind in the forums so here goes:

I've read more reviews of lenses over the past week than I'd care to recall and I've changed my mind so many times it's doing my head in. I'm thinking prime lenses within a budget of about 1000 to be used to take portraits from headshots up to full figure, and sometimes within a landscape. Basically wide to short tele.

In the blue corner there is the Sigma route of (for example) 28mm EX, 50mm EX and 70mm EX which leaves me enough for a battery grip and a second battery while in the red corner is the Pentax 21mm DA ltd, 40mm DA ltd and 70mm DA ltd which slightly exceeds my budget but what the wife doesn't know won't hurt her, right?

I'd appreciate any opinions of these lenses. I'm open to alternative suggestions - other than Canon L series that is :-P

Thank you.

Are you sure about primes? The 16-45mm lens is superb. Ask Mattmatic, he's got one too.

The 16-45 is an obvious option as Pete suggests, but you could always wait a month (or so) and go for the new DA* 16-50mm when it comes out.

I have the 16-45mm, but I am also fortunate enough to own 31, 43 and 77mm FA limiteds. I use the 31 and the 77 a lot now I have started doing portrait work, but I think I could live without the 43 so I am thinking of selling it and the 16-45 to fund the 16-50 if it is any good. (I would sell you a kidney before the 31 or 77 though).

If you want to stick with primes, with your budget I would go for the 21 and the 70, but I would give the 40 a miss and buy the 50mm f1.4 instead, arguably a better lens, faster good dof and 75 cheaper.

If you want to cover macro as well, as a bonus, you could substitute the 70mm DA for the Sigma EX 70mm Macro.

This would not leave you enough for a grip, but it would leave you enough for an extra pentax battery or an extra 4-5 compatible batteries from 7 Day shop for 6.99 each that last easily over half as long as the pentax job (probably longer).

I have a Pentax K10 D and 17-70 sigma lens which is fantastic works very well with K10D fast autofocus and very sharp or go with 16-45mm as Pete suggests they are both excellent lenses.

I am still considering the 16-45 plus a 70 but I was hoping for a two stop improvement on the kit lens. The 16-50 DA* has that advantage (in addition to others, we hope) but...when is it likely to put in an appearance? End of July? September? I've heard both quoted. I suppose my biggest concern with the 16-45 is how much of an improvement can I expect in real terms over the kit lens, specifically with regards to sharpness across the frame and vignetting?
