A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

In terms of DOF, exposure settings etc. with all things held constant (except maybe focal length).

Everyone else answered your technical question, I'll just say that the f/1.2 lenses are usually found on 56mm or 75mm lenses, which give them the same look as an 85 f/1.8 and 112 f/1.8 respectively.

These are still very capable portrait lenses... and while you would notice a difference side-by-side with full frame lenses, it will be slight. Reviews and sample images:
