Agreed. I vividly remember FP mentioning the Ruby/Ice/Emerald Medusa lenses - mostly because it was revolving around a set being part of a special contest that never really transpired. Amazing, though.
That Medusa looks really cool, but the way the way the lens "shine", reflects and transparency in the sunglight suggest to me it's a custom lens from a third party. That makes me wonder how long until we start seeing some Medusa customs on here.
