Hi Richard, I used live view with the 500mm II and the 2X to shoot wading herons. I used the 1st magnification setting. It worked fine as far as getting in focus shots but was pretty challenging to execute - would be pretty easy with a stationary subject. I needed IS mode I to calm vibrations from the wind enough to focus too. This was the only way I could get a manually focused in focus image - I just couldn't do it through the viewfinder.

John,

Shouldn't we be able to use Live View for auto focus for f/8 or greater max aperture for stationary birds using a tripod?

Since 1000mm-1200mm is too long for BIF, it would still be nice to get some long range static shots with this combo.

With the 1D IV I wouldn't completely miss AF with a 2x extender on it, manual would suffice. I would miss it for moving objects though.

Yes you could and I have used manual focus on the 1D4 at 1000mm because AF had trouble with the specific circumstance....low light, small bird standing in rushing water.

Thanks guys!

Just to clarify, I was referring to using "Auto-Focus" via Live Mode on the LCD at a max lens aperture of f/8 or smaller, and all of your responses were that Manual-Focusing in live view @1000mm was not a problem.

So, it sounds like the answer is no, that AF won't work whether it's in live view mode or through the VF. I wasn't sure if live view would be more sensitive than manually focusing with the VF.

Rich, my comments really weren't aimed at this. I was saying based on focusing with the view you see in the view finder, with or without confirmation. Just on how crisp your subject is from just what you see, kind of like the film days before AF existed. I have had pretty good luck shooting wildlife in the bushes doing this. Live View not used in the scenario, although it could be. The 1D IV does very well in manual through the viewfinder and I have heard the 1D X is even better.
