No, but it would be a challenge to make a retrofocus pancake :-)
Retrofocus adds weight and size to the design ...

Since I got the *ist D 8 months ago, my 20mm has become my most used

I have noticed that photo jounalists very often uses a wide angle
(24mm),
then go very close to the subject. At f8 almost no focussing is needed.
Everything will be sharp.

Making a pancake lens in that focal length range would be much more
difficult. Apologies if it wasn't clear that that was what I meant. :-)

Think about the simplest possible lens, with just a single element (eg a
magnifying glass). Its focal length is the distance

As I read the chart, they're noty planning a 20-30 zoom; there
is expected to be a prime lens released with a focal length
somewhere in the 20-30 mm range

Then I'd shop for a fast telephoto lens. I seem to use my 105mm a lot
lately.

Lens options for the *ist-DS

Setting aside the distinctions between DA, D-FA
Setting aside the distinctions between DA, D-FA, FA, F, A, M, and basic
K lenses, I wanted to discuss focal lengths for the *ist-DS.
I've got my zoom kit pretty much where I want it for now:
SMC Pentax-DA 16-45mm f/4 ED AL
SMC Pentax-FA 28-105mm f/3.2-4.5 IF AL
SMC Pentax-FA 80-320mm
But then along comes the SMC Pentax-DA 40mm f/2.8 Ltd. This looks like an
interesting lens. Its pros are: Compactness, great image quality, great bokeh,
solid construction. Its cons are: wide open is only f/2.8, and it doesn't seem
to fit into any particular suite of lenses.

There is also the D FA 100 f2.8 macro for your 50-135 gap.
That's a good thought. I almost forgot that I had considered it. My
only concern is that I've understood that lens to be, well, a bit too
sharp for things like tight portraits. Is that the case?

I see the DA 40 as an alternative to the 35. The 50 is much faster.
The real advantage of the 40 is that it is so small (and has that
compact hood) that it fits easily under a coat in bad wether or even in
a big coat pocket. It's just flatter than many other SLR/lens
combinations.

I think I've settled on what to work on accumulating: a 35mm f/2, a

Can I recommend the Tamron 90/2.8. You can get a used MF one for
100-120GBP. And the AF version new could be cheaper than the FA100.
I'd second that, the new version gets some very positive comments.

Not sure what you are asking, Steve. Pentax has wide-angle, retrofocus lenses.
Are you suggesting that such can't be a pancake design? I wouldn't know. Anyone
else?
