The Beattie screens are known to perform progressively more poorly as
the lens gets wider. I didn't know it started as early as 35mm. In any
case, the Oly 2 series screens do not have this problem and are as
bright as the Beatties. Still available new, too.

A problem I have is with wide angle lens 35 and wider
in focusing them on subject not near to or at
infinity. I had a number of travel shots with a 35 f2
that came out out of focus(not camera shake) like I
was off( I'm pushing gafferhood and maybe need new
eyeglasses though at work I was tested 20 20/10 with
eyeglasses just 3 months ago.)
I use Beattie screens in a 4T. It really came home
this weekend when I was experimenting with a 35-85 f2
zoom. I would focus at 35mm and then zoom to 80 and it
was off by a lot. (a 4 by 6 maybe okay but noticable).
I am going to try using the standard 1-13 screen and
see if this helps.
