For those who might remember this one.... Just got a clean Sensorex as a inexpensive revisit to my first 35mm. The meter needle seems to work, but the bombsite match needle (moved by the outrigger lens arm) is too far down in it's adjusting compensation. It only moves up about 1/4 of the frame. And it seems backwards... as I raise the match needle up to center on the meter needle, and the aperature shrinks when it should open, I would think. I can't remember this from the one I had years ago, but it seems the match needle is off it's calibration? I can get the needle to halfway up in the screen if I'm at f16 and 1000/sec. I had to put in a zinc air 675 to get it running, but the +.1 volt wouldn't have that much of an effect. These finders come off and I think I can get at the needle by unscrewing the screen, but in retrospect, the match needle probably may be adjusted under the top housing somewhere... I probably could use it manually until I figure it out. I normally use OMs, and this is one heavy machine... -Bob G.
