    The best one I know of is this: DontFearTheProfunctorOptics. Hopefully someone else has it translated to other languages - I guess typeclass would be a huge bottleneck.

    Profunctor optics and the journey to learn the differences between the representations will clear things up. https://github.com/hablapps/DontFearTheProfunctorOptics/blob/master/Optics.md is a great read. The Profunctor have more flexible composition which is both a good and bad thing and is still debated. But understanding them and the notions of Profunctors generally applied to a domain will align your current natural intuition.
