I use my 35 Limited for indoor shots of family and friends and there is no noticeable distortion. The 40mm has the advantage of much faster autofocus (compared to my 35) - in fact it's probably the fastest focusing lens in Pentax mount - so it should be ideal for you.

Not from Pentax though:

Anyone want to hazard a guess as to what this thing is going to cost?

The Sigma 10-20 is a fabulous lens - sharp (except the corners wide open, but that's true of most lenses), but also quite bulky. The newer version (constant f3.5) is faster but inferior in IQ to the older version (f4-5.6).

The 8-16 is supposed to be sharper than the 10-20, and is also (obviously) wider. However although it is a rectilinear lens it does have a 'fisheye-style' bulbous front element, which means no filters and a greater risk of damage/rain on front element/etc.

Because some people (I'm not among them) think that the purchase by Ricoh will lead to the death of Pentax's K-mount DSLRs (either by no new DSLRs, or not being K-mount, or any other permutation) and that they will therefore have to switch systems. The cost of switching is greater the more Pentax kit you have (i.e. with the exception of those who bought at pre-hike prices, you won't get back what you paid for it), so for those who are of that opinion it makes sense to not 'get in any deeper'.

Their listing for the DFA 100 Macro has a picture of the FA version. Doesn't exactly fill one with confidence!

Very nice collection indeed. I have read in a few places that, for whatever reason, SDM lenses seem to focus faster on the K5 than the same copy of a lens will do on older bodies. Obviously the motor is the same, but maybe the AF is achieving lock quicker or something?

I voted yes: I've been planning for a while to get an FA77 once I get a bunch of work-related stuff sorted out, and on reflection the announcement hasn't changed that. One reason is that I'm actually quite upbeat about the deal: Ricoh actually want the camera division, so that puts them one step above Hoya. The other reason is that I feel my camera kit will be essentially complete with the addition of an FA77, so I wouldn't necessarily need to jump ship in the unlikely event that Pentax's DSLRs aren't part of Ricoh's plans.

Hoya's original purchase of Pentax was a hostile takeover: the negotiations with the board broke down, apparently because the board wanted assurances about the camera division that Hoya was unwilling to give. Hoya only really wanted the medical division - as shown by the abandonment of the lens roadmap and the serious drop in quality control (e.g. K5 sensor staining, not fixing SDM) since they bought Pentax. Whatever Ricoh's plans for Pentax the simple fact of them no longer being owned by Hoya is, I think, cause for celebration.

Just a quick update on this: according to Nikkei (Japanese equivalent of the FT):
I was initially worried about this deal, but having read that I'm not actually quite excited: it sounds (to me at least) as if Ricoh are at least planning to do something similar with Pentax as Sony did with Minolta.

To paraphrase a long-forgotten post I read on some other camera forum, the last thing you want is someone who has a knife between your camera strap and your person having trouble cutting the camera strap. Even if you don't suffer injury as a result, surely "I have a knife, give me your camera" is an entirely adequate substitute (from their point of view) in the event they cannot cut through the strap?

On the same note, many of these 'addon' straps have "quick release" clasps, in which case the would-be thief need not have a knife at all to be able to snatch your camera in an instant.
