While we all have our own shooting style and there is no such thing as which way is better than the other, but I still think that combining the focusing and firing actions in one stoke is the natural way to go. All camera manufacturers do that, aren't they?

The great Russian hack brings most of the 10D features back to the
300D. For the focusing mode, it offered the 1) One shot, 2) AI
Servo and 3) the AF Servo (continoue focus tracking) mode. Sadly,
the AF Servo mode is for viewing only, you cannot fire the shutter,
at least not in a usual way.
The DIY circuit overcomes the shutter firing issue. It is based on
many DIY ideas floating around the net in making a cable release.
You can search the net to get the details.
The tricky part is 1) to use a single button for both half-depress
and full-depress actions just like our 300D, 2) the most
interesting part is to open circuit the half-depress right before
short circuit for the full-depress.
Of course, the first thing to do is to select "SE" mode in the
300D. Pressing the spring loaded button just touching but NOT
actuating the micro-switch moves the magnet in the vicinity of the
reed switch and hence closed the ring-sleeve 2.5mm plug to the
camera. The camera goes into the continous focus tracking mode.
Further pressing the button actuates the micro-switch. The first
thing happened is to open circuit the ring-sleeve. A brief moment
later, the tip-sleeve is short circuited causing the camera shutter
to fire.
It works. Perfectly. I can use the AF-Sevro without all the hassles
in the Sport mode (RAW, ISO and select my favorite metering mode).
The most difficult part is to make a case able to be placed near
the original shutter for easy operation.
Any comments welcome.

--Thanks for this I did it, put the camera in servo and the focus
works and shutter fires but I don't get the 4 shot burst is that
possible to achieve? probably asking too much but if it is that
would be great
Are there supposed to be images here? Why can't I see any?

Very interesting - i think i will have a try at this. So all i need are the 2 roller switches, some harddrive cable (which i have laying all over my home office) and a 2.5mm plug. Anything special about the plug? Could you post a pic of the plug connection also?
Here are pictures of my functional prototype which I've tape
mounted to the inside of the grip, positioned for a middle finger
trigger. Pressing lightly triggers the inside switch for the AF,
and then fully to activate the second, the Shutter switch.
I've used two micro lever switch where I bent one lever to be
higher then the other. The two swiches have been glued together,
and then used strips off a flat computer hard-drive cable for the
wiring.
Not very pretty, since I haven't figured out a housing or "button"
cover yet, but it seems to feel and function pretty well on some
random traffic shots. Enjoy!

And the red, purple and green lines what are those for?
