No problems, some more perhaps?

Remember mine's not a Katz eye (it's a cut-down Minolta screen),
but my exposure appears to be pretty accurate.... or about as "accurate"
as it was with the stock screen. I used to generally add +0.5EV to
"expose-to-the-right" anyway.
One way I've tested mine is with a couple of screwmount lenses...
an SMC 55/1.8 and a Lentar 300/5.5. Assuming the aperture ring is still
correct, I was able to use it to see how the meter reacted at different
f-stops without stopping down. Pointed at a static, solid-color object, I
was able to click down in 1/2-stop increments. As I did that, the camera
changed its meter in 1/2-stop increments to match. At least until f/11 or
so when things were getting too dark to meter anyway (indoors in poor
lighting), it was more or less dead-on.
I've notice my cut-down screen is slightly off-center. That might
actually help a bit vs. the exactly centered commercial version.
