Most of my pictures I had been slightly during the post again and turn a few degrees left or right. A work that takes time, and in some cases the loss of important details in the edge region of the images has the effect. This focusing screen, the problem is finally solved. Almost none of my pictures is geared more inadvertently oblique. In addition, you can also fine align the objects along the third lines. Changing the focusing screen was a breeze: Read the instructions or watch on Youtube times for a corresponding video. The procedure takes a minute. In my 6D I subsequently have changed the settings on this matte screen EC-D. Despite the euphoria: the focusing screen is a penny article.
