Hello all, I am having trouble getting the viewfinder virtual horizon function working. It is mentioned in D.Young book about assigning a button for it, so I looked in the English user manual and found info on page 231 and page 245 about setting the Fn button in custom setting f3. I have done this and pressed the Fn button but nothing happens. Am I missing out something out in the setup? The virtual horizon on the LCD display works fine. Ps In Darrel's book he refers to dots appearing left and right, am I right in thinking that these are the exposure indicators as given in the info on page 231 of the manual.
