Look at this since you have a Loki:

A lens on melee weapon would achieve the same numbers as a lens on Loki. Apparently this is also the best way to farm Focus since you can reach the cap in less than 40 minutes.

Alteratively, you could get Hushed Invisibility, put the lens on Loki and use a Tonkor.

Low level enemies die in 1 hit anyway and due to how Affinity works, killing higher level enemies is not worth it.
