I'm not sure, Nicki. I'm hoping Dennis will pipe up as he's pretty good at this stuff. I know, for me, it is pretty easy to adjust my ISO and white balance by dragging my finger across the flip out screen. I also never use auto focus but always use my 2 second timer with a remote, so I don't mess with the camera on the tripod. My x10 screw on macro won't work on my 100mm f lens either. I get the same problem. Sometimes backing up a bit helps, though.
