@Linegear Japan to clarify their relationship with Zero for you. Very good people over at Linegear. Their lenses are top notch in my book! The majority of my metal pairs with aftermarket lenses have linegear lenses. My o-matter pairs get Ikon. That's just me though. Never tried Fuse lenses.That's interesting information. So, I need to update my knowledge, OK Zero is no longer with Linegear now. I'll try Fuse + and Revant Elite HC3, and we'll see the results.
