Yes, it's a combination of software and shooting at very close distance to get this look.
I rarely use tubes nowadays.
This lens usually goes on the D500 to get the narrower field of view, and the resolution is more then enough since I'm using it at the soft end.

D500 at F1.4 Guerilla parking and a quick run to get this shot before the villagers would get to close for a bite....
