The exposure meter needle works as it should ...
I'm using an MR-9 adapter with a tiny silver-oxide battery, and the
meter needle behaves quite linearly.
I suspect the shutter itself travels slower than 1/1000 ~ 1/500 and
its barely noticeable at 1/250 on the exposed film, and none at 1/125
~ 1/60.
Most of my shots were at 1/125 to 1 sec. In fact, I can't tell if I
ever exposed anything at 1/1000 or 1/500 since I own it back in 2007.
Fernando.
