Exposure compensation database for K, M lenses

[GeneV]

Is there a thread, article or FAQ that assembles the exposure compensation for metering completely manual lenses on newer digital bodies? If not, wouldn't this make a good sticky, or does it vary with the camera body?

I find a great deal of difference between the behaviors of manual lenses, which might even influence a close choice in which older lens to buy.

For example, I find the Cosina 55mm f/1.2 metering quirks are slightly more easily dealt with than the M-50mm f/1.4.

Is there any interest in starting a sticky thread sharing this information, or has it already been done?
