Yongnuo creates near-clone of Canon 35mm f/2

You are derailing the topic completely.

If two lenses have aspherical elements, and two photos have birch trees in them – neither is necessarily a ripoff. If two lenses are double-gauss designs, and two photos have a pond surrounded by trees – they are likely similar, yet not copies. However, if you take someone’s readily shot photo from their memory card, and, after some time passes, start printing it, and selling it under your name – this is ripping off, which metaphorically describes what yungnuo did with this lens.

Why can’t some draw a line between improvement on the existing stock – enhancing progress, and embezzlement of others’ ideas and achievements – hindering progress? These are completely different in incentives they provide, in effort required, and results they yield! Stop mixing these up!
