Default Need a low shutter lag point and shoot digital

Hi. I need some help. I want to get a small
point and shoot digital camera, but I am concerned
about the shutter lag. Please do not recommend a
DSLR, as I have a Canon 1D Mark II and 10D cameras
and plenty of lenses to go with them. I'm looking
for something small, some specs that are important
to me:

5 megapixels or larger,
auto, manual, aperture priority modes,
3x optical zoom minimum, with autofocus,
built in flash,
compact flash I (and type II would be nice) cards,
under about $500,
reasonably low shutter lag for this type of camera.

Nice but not necessary: raw mode output.

The question is, what is a reasonably low shutter
lag on such cameras these days? I can't seem to find
many specs. Lag only seems to be mentioned rarely
in reviews, and the manufacturers do not seem to
give it. Does someone know of a site (especially a
table that compares the lag times, measured in a uniform
way) with lag times? I want lag time from shutter press,
autofocus, exposure calculation to release of the shutter,
and I do not consider lag time with manual focus to be
relevant for my purposes.

I have a Canon G1 and shutter lag is awful. It often seems
to take 0.5 to 1 second or longer to acquire focus and shoot.
(Of course this is quite maddening after using the 1D Mark II
with its 40 millisecond lag ;-).

One camera that I am looking at is the Canon A95, but I
can not find shutter lag info. It also only uses
compact flash type I.

Any help would be appreciated,
Thanks in advance,

Roger

I'm no expert on any of this, but one thing to make sure of is that you
can turn off the flash. If you need to make multiple sequential shots,
charging a flash can be a limiting factor rather than shutter lag.
Likewise, if you _need_ the flash, make sure that you check the specs for
flash charge time.

Not really what you're specs are but you could also look at the
KonicaMinolta G530 or (G500 or G600). The shutter lag is almost
unnoticable after focus. No CF card, but SD...
Also quite a nr of manual setting possible, no RAW output.

Even if you can find the specs, the formal definition of shutter lag
excludes the AF time.

The P&S cameras use the CCD for AF and have to read out several frames to
focus. So the fastest P&S is going to be a lot slower than the slowest dSLR.

Even worse, the CCD-based AF systems often focus on something contrasty in
the background instead of your subject. This makes the EVF cameras
attractive, since you can see when the AF is messing up.

I've seen my Canon PS-400 do exactly the opposite; focus on something in
the foreground when my subject was further away.

Well, yes. I should have said "focus on something other than the subject
when the subject has relatively low contrast". It's _really_ irritating.

As I understand it, the dSLRs can do that also, but the AF sensors are quite
a bit smaller so it's much less of a problem (if you select the AF sensor
manuallyg).
