Mirror lockup is only nessesary when precise focus is needed to reduce camera movement and vibration from the reflex mirror.
Please correct me if I am wrong.

It really does depend on which camera you have and the mount....

Could someone let me know if the lockup is necessary, and if so, how some of the great photos I have seen from the D10 were managed?
Thanks heaps in anticipation

There is a version of the Canon 20D that has the IR filter removed. It has mirror lockup (and it needs it too)
