In my opinion an articulated display (one that rotates to allow viewing at different angles) is a big advantage for a modern camera. But I see that most professional and/or more expensive cameras do not offer it.
An articulated display is a long-time standard feature for all video camcorders, yet most modern DSLRs with video capabilities offer no such feature.
What is the reason for not making the articulated display a 'standard" feature on any high-end camera?
