7 point AF

[jonlg]

I shoot motorsports with a D60 and have used AI Servo with the centre focus point.

I'm just trying to attain if the 10D/EOS30 AF is capable of tracking using all 7 points, and in general if it is more accurate.

I'm interseted in EOS 30 owners and how theirs performs in AI Servo
mode.
How good, how bad.

EXACTLY.

My last outing had many example of this oversight.
I would focus on the eyes, and pan down because the model is
standing. Then snap. Guess what Back Focused. Because the
distance from the Model's Eye to the camera is longer than the
distance from the stomach to the camera. So the immediate back
ground was in focus instead.

You have to think in terms of distance to the plane of sharp focus, not the direct distance to the subject, though.

Maybe when shooting groups or action, but when shooting individuals
and portraits, all you need is one. I could actually use just one,
big, center focus point and I would happy.

I think that topic may be forgotten by people rushing to talk about
the new 10D but it is just a little question :

with my D30, i usually focus only with the focus point in the
middle of the viewfinder, and then i compose my picture..

Is it useful for me to have 7 point AF if i decide to only focus on
the middle one ? is 7 point AF more precise in my case or is it
only when you let the camera automatically choose the focus subject
?

AI Servo

This is a great camera for amateur sport shooters. Lock on to a moving subject in AI Servo with ECF, keep the shutter pressed halfway, and the camera tracks the subject as it moves from side to side (sensor to sensor) and towards or away from you. It confirms side to side movement with red sensor flashes! Very cool. AI Servo is better at nailing sharp images than the older Elans and A2.

Sure no eye control but.........a little more reliable tha a D60
