Hi Peter,
from just a fourtnights experience with the 2-4 in an OM-2 I'd certainly
recommend this screen. Though I wouldn't say the focus 'snaps' in like
with microprisms, the greater overall brightness makes focussing a lot
easier in two ways:
a) while focussing lenses of moderate aperture (e.g. zooms).
b) possibly more important: to determine the extent of the DOF-zone with
the DOF-preview button pressed. As the viewfinder darkens in that
situation, every little bit of additional brightness is very welcome to
me. Furthermore, as the surface structure of this screen is finer, you
don't get this 'grainyness' with visible Fresnel-rings so early, when
previewing at a small aperture.
All the best,
Soenke, Hamburg
