Focus speed: Rebel XT vs 30D (1 Viewer)

Hi All,

Since I can't afford a Mark11, I'm considering the new 30d to achieve faster focus while in AI servo mode.

You may find this link useful, I am having the same thoughts to get that bit extra from my 400 5.6? My logic is that the 20d is better than the 350d, so if, as I have read, the 30d is better than both of those it may well be worth the upgrade?

# The EOS 20D has 9 autofocus zones, the Digital Rebel XT has 7
# The EOS 20D provides full cross-type performance with maximum apertures as small as f5.6, yet it achieves up to 3 times the standard focusing precision when used with EF lenses featuring maximum apertures larger than or equal to f/2.8. The autofocus system of the Digital Rebel XT is inherited from the film Rebel XT body and has normal precision f5.6 sensors.
# The EOS 20D autofocus is specified to operate in 1 stop lower light than the Digital Rebel autofocus (-0.5 EV vs +0/5 EV)
# The EOS 20D autofocus is faster than the autofocus on the Digital Rebel XT

Plus the faster frame rate and useable 3200iso.

I will follow this link with interest?
