Canon Backfocus on CCD Camera


Based on the Interweb, the specified backfocus on the EF lenses are 44mm

Is it at all possible to use a CCD imaging train combo that will exceed this recommendation or will it just mean my Infinity marks on my lens are not really infinity?

I'd like to at least reuse one of my Canon lenses with a CCD combo before buying another longer focal length lens.
