Canon 80D pictures a overexposed

[Assaf]

i just cant get my head around it.

the pictures looks good on live view. the histogram looks fine when i take the picture its completly overexposed.
i have being told it might have something to do with the lens im using is very old (manual 50mm 1.8 olympus)
but this lens worked great with my old camera (600D)

is there any reason for why the camera is suddenly decided to give me a headache?

My recollection from the film days is that the main purpose of an incident light meter was to determine the color temperature, not the strength, of the incident light. IOW, to try to overcome the bias of your lying eyes and determine what filter was needed, if any. But only a reflected light meter could tell you what exposure was required. Is there really more to it than that?

To have a meter read the color of the light you need a color temperature meter and they were not cheap. An incident meter is a meter as said earlier for measuring the light at the subject. A reflective light meter is used at the camera position to measure the light. An incident light meter can be identified by having a large dome or flat white sensor. Gossen meters often did both with attachments.
