I pulled out my 85Lii to use and found out that the aperture blades were stuck at the smallest aperture F2x. Freaking out & not sure what to do. I've tried everything. Gives a communication error with the camera. Suggestions please?

Sometimes a lens can be removed when in live view or DOF preview and the blades will remain in position. I would try that and see what happens. Worst case scenario send it in. 5D Mark III / 70-200 2.8L IS II / 24-105L / 50 1.8 stm / Tamron 70-300 VC / Sigma 85mm 1.4 Art

If I'm on F16 and I hold down the DOF button and open up the aperture to say F8, I hear no sounds of the lens even trying to open it up. However, when I do it the other way (F2 to F16 for example), even though it is stuck on F16, it keeps trying to close it down. Moments {Photo + Cinema}
