As the kit lens 12-50mm compared to the camera OM-D M-E5 has fallen quite large and a little too much vorbaut, there is a risk that you offend the lens somewhere. The sun visor therefore acts not only against stray light but is also a less expensive lens cover. That it is not an original part of Olympus, does not interfere. Everything fits, nothing wobbles. Inexpensive and useful it is as I said. What more do you want.
