I take it you're using a 300D with the WASIA firmware hack? If so, I don't actually think it works properly. i.e. it hunts but won't let you take a photo.

Oh, it would appear that I am wrong. Just found this:

"Tricking AI servo, three ways I know... (works in ANY mode)

1. Achieve focus lock on a subject and then whilst keeping the shutter half depressed and the subject centered, move the lens focus ring - camera drops into AI servo and will stay there as long as the shutter is kept half depressed. (Only works with lenses that support full time manual focusing such as Canon USM and Sigma HSM lenses)

2. Achieve focus lock on a subject and whilst keeping the shutter half depressed use the lens zoom mechanism to zoom in slightly. Camera drops into AI servo and will stay there as long as the shutter is kept half depressed. Obviously only works with zoom lenses and doesn't work with parfocal lenses.

3. Achieve focus lock on a relatively close subject and then whilst keeping the subject centered, and the shutter button half depressed take a step forward. Camera drops into AI servo and will stay there as long as the shutter is kept half depressed.

All three methods take a little practice and some methods work better with some lenses than others. Fairly easy to do though."

I'm not sure if the instructions I posted will work for you. I never got it to work myself, but admittedly I didn't try very hard. There are a few bits on the WASIA firmware which don't work.

The most useful bit I found was the mirror lock.

Meh :/

Sound complicated I think I'll steer clear for the time being
