Seems similar to this beast: https://www.kenrockwell.com/nikon/135mm-f2-dc.htm

I've got the 105 version, its amazing. 135 would get you even more buttery backgrounds.

Yeah, the Sony variant is an absolute monster. Super dooper sharp, but it weighs about 4 station wagons, even for a mirrorless lens.
