Focusing Screen:
The article is of known good quality Canon.
The grid simplifies the orientation of the camera, for example of landscape photography significantly. In portrait photography, I feel this rather disturbing. The advantage of the 1/3 division and orientation prevails for me. A regular exchange I would not recommend because of the danger of dust inclusions.
