someone please help me...driving me mad!

Hey guys...love the forum, and hoping someone here can help me out with their own experiences.

I am a professional archaeologist in the UK, and I have just set up a mast for aerial shots on site. I want to shoot pics using the laptop with the camera remotely tethered, and downloaded the EOS utility software. I was under the impression that I could auto focus whilst also having live view on screen, but it seems that if live view is on with the viewfinder picture on the screen I cannot autofocus...only press the shutter button and get an out of focus picture??

Is there any way that I can get over this?

Really help someone can help! cheers!

This is going to be a tough assignment on top of a pole (mast)!  Everything in focus would be a whole lot simpler.

First you are going to have to know the DOF.  From that you may figure out a f rario that will do what you ask.
