Nope Gen 2 Frame with Gen 2 Lenses. Gen 1 Frame is bigger compared to a Gen 2 Frame. Gen 1 lenses are 65mm Gen 2 lenses are 62mm so it would fall out of a Gen 1 Frame. I custom cut those vented lens like that for more air flow. Is that what you were referring to? I might just keep these after all if no one is showing interests.
