ME Super question

I have an ME Super... why can't I adjust the exposure compensation +1 or +2 when using ISO1600 film, and cannot adjust compensation +2 ( but can +1) when using ISO800 film?

Seems dumb, just leave the shutter open longer, the film speed should have nothing to do with it.

The M series max out at ISO 1600. The primitive electronics can't compensate for a higher ISO. We're talking 1970s technology here...

Set the camera to meter at ISO 1600 and just stop the lens down 1 more stop (or increase shutter speed 1 stop) to get an ISO 3200 exposure. And 2 stops for ISO 6400, etc. That seems simple enough.

I don't get that... it's the same as moving the ISO dial from ISO1600 to ISO800. There, bam, now you have a full stop of exposure compensation.

They were just nested selectors where, for example iso 800 with EV at -1 is the same setting position as iso 1600 at EV 0
The Ricoh XR-2 (year 1977, before the ME super) and KR-10 (of 1980) go up to iso 3200 with EV -0
I don't know what the fastest C41 films were in 1980 but I recall using Kodak iso 1600 at times

I was going to say you should be able to manually do it as well.

Yeah, I can also just flip it into manual mode since it's an ME Super and not a regular ME. It just seemed odd.

Just replaced the light seals and loaded a roll of T-Max 100 in there, and I'm going to give this thing a shot.

It has to do with how the exposure comp works. Notice that the ASA/ISO setting is just a window in the exposure comp dial. Both use the same mechanism (most likely a strip of electrical resistive material under the dial). Setting the exposure comp is the same as setting the ASA/ISO, only easier. It might have been possible to simply support a high ISO (say 6400), but then the complaint would be that it is not possible to use 1+ or 2+ EC at that speed.
