Talk:Focus Lens/@comment-2604:4080:11C5:81A0:49E2:46DA:3568:9553-20191129022711

No one has really answered this in the comments and the info on the wiki seems confusing

This seems to imply that a weapon that doesn't have a lens loses out on affinity conversion:

But these seems to imply the 75% affinity is distributed only between weapons that have lenses. i.e. it's worse to equip lenses on more weapons:
 * Allied kills distribute Affinity non-linearly. 25% goes to the Warframe and the remaining 75% shared among all equipped weapons. If a Rank-30 weapon does not contain a Focus Lens, it will not convert any affinity obtained from ally kills into Focus points.
 * 1) Assuming only one weapon equipped for simplicity. Total focus is the same if all weapons have lenses. If some weapons have no lens or a mix of greater and lesser weapon lenses is used an intermediate amount of focus will be earned.
