Why W.O. diagonals do not feature an Adjustable alignment system?
•Having an adjustable alignment system is an admission that the diagonal can go out of collimation due to poor mechanical construction. Thanks to the patented design of WO diagonals, you will always have a diagonal that performs as perfectly as on the first day you got it!
