The 2-13 or 2-4 may be not very bright at F11, but it provide the
finest grain for focusing with long small aperture tele. I have tried
many different focusing screen including Canon Laser Matte, Minolta
Acute Matte, Beattie... the Olympus 2-series screen was the brightest
and finest one among them. But sometimes it has too fine grain that
make the focusing with super wide a bit difficult (I only use matte
area for focusing).
