No, there are others. Nikon/Canon don't sit in judgment of their owners intelligence, and simply give them this feature - no questions asked.
Pentax makes a whole big deal on that K10D owners would not be smart enough to use it leading to more warranty repairs - EVEN THOUGH A RESET SETTING WOULD BE SUPPLIED! FOOLPROOF!
Yet, as to listening to their customers, they are refusing this feature for the K10D.
