Talk:Focus Lens/@comment-38.66.40.114-20160111062709

It should be noted that Greater Lense blueprints require 4 lenses of the same type to craft, so expect to do some serious grinding to get the materials. You might find it more worthwhile to put the same lense type on your favorite warframe/weapon combo to get about the same Focus gain or more than you would making a Greater Lens. If you get lucky enough to find all the lenses you need, I guess you may as well get the Greater Lens, but unless that happens, it's SO not worth the grind.

Also, to those complaining about enemy levels in Sortie missions, this is endgame content. Focus unlocks the most powerful abilities in the game, so it's only natural that you would need some of the most powerful weapons, warframes, and mods in order to obtain them. Personally, I find that a Hek with 1-2 Forma and Scattered Justice from Steel Meridian will be enough to handle nearly any enemy, if it's allowed.
