How about hacking the focus confirmation issue?
I would like to use other lenses (manual M42) but without adapter with focus confirmation chip that fools camera into believing it is dealing with original Canon lens.

Nothing is 100% safe. But I got it right. You should be able too. If really brick it, just change to 550D or 7D.

From my findings, with this hack, ISOs lower than 100 don’t really work. It’s just a software trick.

If you are on Av and normally have ISO 100 f2.8 1/60, when you switch to ISO 50 you should have f2.8 1/30, right? Well, yes, that’s what the camera tells you.
When you compare the two images, they should have the same level of exposure, as well. But they don’t. One is correctly exposed (ISO 100) and the other one is badly burned (ISO 50).

The ISO 50 will actually be ISO 100 with more exposure, with the camera trying to pull back detail from burned areas. You can do that in your RAW editor just as well, has nothing to do with actual sensitivity.

My 2 cents.

Even with access to 16 to 3200 ISO . . as you mentioned, I don’t think the sensor would be capabale of getting usable images. 3200 would be very grainy I imagine.
