Here's another related DPReview thread that shows more examples of the 85mm GM's cateye bokeh:

As I mentioned earlier, the only current lens I've seen that doesn't have cateye bokeh balls is the 100mm STF. It's free of any mechanical vignetting, but the 85mm GM isn't.

Here are some (uncropped) samples showing bokeh balls across the frame on the 85mm f1.4. First two are taken at minimum focusing distance. Certainly not perfectly spherical, but pretty round. Might be a consequence of close focusing.

The third image where I focused further showed catseyes.

I wonder if stacking filters can also be a factor, as it will increase barrel length
