MX vs ME-F
The ASA/ISO dial is a key part of the exposure circuitry. It is a simple rotary potentiometer, and it gets dirty and worn. Reselecting the ISO or adjusting the exposure compensation a couple of times is usually enough to get it right. There are no seals on the dial, so any dust and muck works its way through the dial onto the pot. When it goes wrong like this it underexposes really badly!
However, in the end the pot needs changing. I got it down to an art (when I had an ME-F), and Pentax UK supplied me replacement units for it. I did it to my ME-F, and to two ME-Supers too. However, I'm not sure if the components are so readily available. I suspect that a decent repair centre will do the job for you (There are a couple recommended on this forum).
Hope that helps!

The MX is a totally different beast, being the same specification as the Spotmatic but in a much more compact form and with better GPD based metering. It is fully manual and only needs batteries for the meter. The batteries will easily last a year of even quite intense use - a revelation for digital users who spend their lives recharging....
But the two camera types are totally different in comcept. If you need the electronic-shutter auto exposure then the MX is not like that. But it is robust and reliable, providing you can find a good one. With mechanical shutters the faster speeds may be slow by now, so an overhaul would be a good idea. After that, you have a terrfic camera.
Since getting back to being a bit more serious, I've shot quite a lot of film through both the MEF and the Leica. My shooting has improved, but I notice that I print more of the MEF shots than Leica.
On the other hand, I have recently lost half a roll of Velvia while shooting at a local festival due to depending on the AE function. I don't think I trust it!
So-maybe an MX will do double duty!
I was lent a leica M3 outfit a while ago, and I absolutely hated it.
Use it in manual mode, and it will give you focus confirmation and indicate the correct exposure. It's got AF for when you may need it. And it's much newer than the MX and MEF, so should give you longer service.

I hate having too many cameras. Something may have to go. Are MEF parts becoming scarce?

The MX is already on its way. I'll keep the MEF, and use it as well, but I am a little gun shy now.
Is this to be expected?
The MX uses a mechanical, horizontally running rubberised silk shutter. The ME series use variations on the Seiko electronic vertically running metal shutter.

Now, I've become suspicious of the ME-F's ability to expose accurately, as the AE function has let me down several times, to the point I worry about the electronic shutter in manual mode.
So-is the MX "better" enough, or should I just continue to build a RF outfit? Opinions solicited for instruction and fun.
