My Canon EF 200/2.8 USM is around 10 years old and recently started overexposing images. After running the same shot through all the f-stops it is clear that the camera exposes correctly at f2.8 and increasingly overexposes the higher the f-stop with f8 already being severely overexposed.
I am also getting occasionally error messages regarding the contacts of the lens but the contacts are clean and not damaged.
I have the same issues with this lens on my Canon 80D and older 40D. All my other lenses work great with these bodies.
Got to be the diaphragm sticking. As BAK suggests, see what happens when you press the DoF button.
