I'm really not qualified to answer on this subject, we just use a nice digital for personal use, a Fuji FinePix 3000 and it does take lenses but I never bought any.
It's a year or so old but it takes great pics and uses regular AA batteries which I like rather than special bats, runs great on rechargables.
But bump for you, maybe some of the pros will see it and shed some enlightenment.
