When I mount an original Nikkor-Q 135mm prime, I'm getting a perfectly neutral reading on the meter, which is similar to my experience with that lens. Fairly nice background blur, but still some funky highlight artifacts when it's wide open.So, it makes sense that it's a wash, and meters out at zero.
A middle of the road lens measures precisely at the center of the scale. Cool!
