Re: Lens fault, not sensors problem...

The lens likely wasn't designed for highly reflective digital sensors so you get a lot of reflections off the sensor. Newer lenses have better coatings on the rear elements to kill these off.

This isn't a lens fault. The reflections that we're seeing are from light at extreme angles going through the layers of film on top of the sensor and generating reflections between the layers.

I notice the same BTW.

Those reflections are not adapter issues, they look like light hitting the sensor then hitting the rear element of the lens, then hitting the sensor, etc.

They do look like that, but it's not likely that this is the case. Light on that edge of your image is hitting at such an extreme angle that reflections off the sensor will not hit the lens on the return path.

What you describe would happen more as you approach center of frame.

CV 12mm f/5.6 on A7. Note the reflections from the light.
