I found that the exposure control is working, but in low light the exposure times are approx. 1/2 of those indicated by my Profisix lightmeter and approx. 1/2 of what an almost mint Electro35GSN performs. Any hints how to correct his other than 'correcting' the ASA setting? |

Winfried,
are you shure that the difference is not due to a different measurement angke of the MC's light meter compared to the others? Half time means one f-stop. That would be quite a lot but still possible. At the other hand I often made the experience that the CDS light meters are not very precise in really low light conditions and that they tend to underexposure. |

Well, as mentioned, I checked it with both the Profisix and the Electro35GSN. The meter of the latter should have a similar metering angle as the one of the Electro35MC. I pointed towards an evenly lit wall, so minor differences in metering angle should not matter. The Profisix is a well-known professional grade light meter. I checked it against a colleague's Lunasix F and it showed exactly the same values. Also, I had good results with some other cameras from the Electro series in low light, so I was amazed the 35MC is obviously one stop off. |

I checked the instructions provided by Roger Provins again and found that the AE is specified up to 4 sec exposure only, maybe it gets inaccurate when setting longer times. A film test will reveal whether the AE system works correctly under normal lighting conditions. Too sad there is no way to see whether the camera sets speeds slower than 1/30. This is a nice feature to check the meter of the E35G's - the one I compared to the 35MC was dead on compared to the Profisix. |

Possible cause can be 'pad of death'.

Fortunately this is a much later design than the generic Electro35G series. The later members of the E35 family like the 35GX/FC/CC all avoided this pad. I am sure the 35MC does not have one, either, also the AE operation seems to be quite different from other Electro35 series cameras. |

Problem solved: checked again against an evenly lit wall and set the aperture to a value for which my lightmeter shows 1 sec, 2 sec, 4 sec. At least the 2 sec and 4 sec exposure seems to be pretty tight to the meter reading. It seems that the shutter behaves oddly in very low light when it is 'forced' to open longer than 4 sec. |

Hi Winfried, I can positively confirm your findings, especially the last one, both of my 35MCs (and also the Petri "Computor II") are somewhat incorrect when exposure times are in the several secs range. |
