Pentax ME and ME Super Light Meter

MESuper-LX · 11-05-2016, 02:14 PM

Hello,

Does anyone knows if light meters in Pentax ME and ME Super are same?
Light meter on ME Super is gone, now I am interested can I take parts from ME?

Thank you!

I suspect not - the cameras have different shutter speed "spreads" IIRC (Super goes up to 1/2000 but only as slow as 4 sec; ME tops at 1/1000 but will do an 8 second exposure). The sensor itself MIGHT be the same, but the electronics behind it are very definitely not.

My understanding is that the sensors themselves were gallium photo diodes (GPD) for both models, but is possible that the rest of the circuitry was modified in the ME-Super to allow 1/2000 sec. shutter speed and the ability to change shutter speeds manually which was lacking in the ME.

Thank you pathdoc and j0n4hpk!

I found and checked electronic scheme in these two cameras. Unfortunately they are different and I do not believe there is any chance to use my ME to fix ME Super,

Man, all things considered that is remarkably and refreshingly simple for a camera electronics diagram!

It is simple scheme, but it is hard to find someone who till repair it.

Light meter in ME Super shows wrong value. I noticed that values I get with its lightmeter are not correct. Like clouded day, low light, 100 ASA film, f/8 and light meter say I need 1/500 or 1/1000 sec... Then I used my Seconic light meter to compare it and it said 1/30 sec.

It was my fathers camera and my first Pentax camera so I want to repair it and shoot few more great photos with it.

Sounds like you need to send it to Eric Hendrickson (pentaxs.com) for repair. He's "Mr Pentax Repair"!!
