I've been shooting pro for 9 year but I never owned a 300mm or 400mm or any lens that needs a teleconverter.Excuse my ignorance but can someone explain in plain english why the camera can't focus at F8.0?
I have a 24-70 2.8L and use F8 all the time... I find it to be the best, sharpest and most natural F-stop for studio work...
Please someone tell me if that is going to affect me or not.
All lenses focus at their maximum aperature. You're lens has a max of 2.8, therefore the autofocus will work splendidly. The camera doesn't close down the aperature until you hit the shutter button (or the dof preview). As long as you don't use teleconverters you should never run into a situation where AF does not work. I would venture to say if you don't know this stuff then you probably shouldn't be getting a 1DX anyway.
I only own ONE lens (24-70 F2.8L) and that is all I need. I don't do sports or birds or need telephoto lenses.
I don't know about this F8.0 phenomenon because it has never been an issue for me.
But I really don't like your comment. I can get any camera I want and it doesn't make me less of a Pro not knowing all this technical stuff... On the contrary, you are either creative or not. You are born with it. I never took classes or studied any photography and I make a ton of money doing what I love.
If you had to learn it, then you didn't have it... I only use the things and features I need in a camera and I've been using 1D's since 2003 so the obvious upgrade from my current 1D IV is the 1D X...
