yeah, I guess that will be a problem if you are trying to match the FOV to the background. I don't even bother with that. Most of my stuff is portraiture and if I need to see feet touching the floor I use an interior model or something else like the car patio I used in the image up the thread.

you might look up a tutorial on photography/Field of View on youtube to get a better understanding on it.
