I have edited the Warframe and Weapons section of this page to more accurately describe and explain how the affinity system works. You are more than welcome to test it yourself with a couple of friends. I spent hours testing in different scenarios. Play a mission with a friend and have him just follow you. You can use any weapon you want to kill a few enemies.

Pay attention to two things at the end: (1) Your weapon Affinity will only be granted to the weapon you used (and your frame, plus objective points). And (2) Your buddy's Affinity will be granted to each of his weapon's identically, split between them (and his frame will receive the same as yours, plus objective points).

This means that if Player A is running around just blowing his ult skill, or nuking everything with an Ogris, that players B, C, and D, are not being screwed out of Affinity. So long as they are in range for each of Player A's kills, they are receiving Affinity for every single one of their weapons, split evenly between them.
