The 135mm is one of my favorite lenses to use. It’s look is so authentic and the bokeh is so convincing . Even though the 135mm requires you to back up much further to achieve a wide shot.
This lens is a Russian lens that has been modified by Iron Glass adapters to create a realistic Anamorphic look. The intention was to mimic the flare and bokeh pattern only. There is no squeezing taking place. I recommend using ND filters to keep the aperture nearly wide during bright scenes .
