Surely you realize that "shutter lag" is often used to describe the sum of
AF lag and shutter lag. In reality it's the contrast detect focusing of
the P&S that causes the AF lag, and while it's not as bad as it was in the
past, it still is much slower than phase-detect AF, especially in
challenging situations.


I've always connsider shutter lag as shutter lag in that it's the differnce
in time between activate the shutter button (in a sense that's the picture
you wish to take) compared to the time it takes the electronics to open the
shutter and store the image in it's buffer.
Focausing has nothin gto do with shutter lag.


It's of little consequence when shooting landscapes in good light. It's of
major concern when photographing children or wild life, or when shooting
in low light.

Well in all these cases I think focus is a seperate issue, as is framing
and decision making.

Using your perception, focusing time is included in the parameters you set.

Why ?

I like to focus before I intend to capture the image.
If I'm going to focus say on the 100M runner in 2012 Olympics
I don;t class that as a 2 year shutter lag.
My shutter lag will be the amount of time it takes for me to begin pressing
the shutter to the time it takes for the image to be captured.
Some might refer to it as a propagation delay which is what I do in
electronics.
'Electricity' travels fast, but at a finite speed.

If it takes 2 years for the event to happen that's not the cameras fault.
Same with focusing, which is focus lag.
I remember the days of film changing lags too, which was removed by being
able to have a 250 exp camera 'back'.
Friends remember processing lags, as being a wedding photographer
they used to have to get the film processed and printed within a few hours.
This meant developing the film while driving to the darkroom in the car,
washing it in meths too, although not while driving.

I'm wondering when the first camera with pre-shutter trigger will be
released
as standard like auto focus is today.

And this has what to do with your definition?
I am not trying to convince you. That is a waste of time. I just don't want
to see a newbie to be mislead.

Not necessarily -- the lens may well be pre-focused.



Yup! Very easy to do in wildlife photography. Just pick your spot and let
the wildlife come to you.

Works with penguins in Antarctica, certainly. Not sure it's so handy with
lions or bears, though.

Works well with birds of prey too, especially eagles. Just put the fish in
an enclosed area and wait for the eagle, or osprey to pounce. \end tag

LOL, just carry some bait and put it exactly where you want the animal
to be, then pre-focus, and wait. While this would be illegal if you were
shooting the animal with a gun, it'd be okay just for photographing the
animal (unless you're in a place where feeding wildlife is forbidden).
It's the perfect workaround to slow contrast-detect auto-focus.

You don't need bait. Just smear some estrus scent from the female animal of
your choice. The male will smell it and become so horny that he will stand
and pose. It's and old animal training secret that works even better if you
are lucky enough to find a male who hasn't been laid in months.

If you can get close enough to the female to obtain her estrus scent,
why do you need to wait for a male? Just tell the female that her
butt doesn't look big in that fur and snap away.
