I hesitate to call it a 'video' or 'promotional product' - even though both of these are true - because it is not just about products - indeed, they come in late, and one of them is a bashed and taped 645Z!
It is the philosophy and the idea of the OVF that is always centre stage with these short films (the branding in the film is Pentax, not Ricoh) that resonates with many of us on this forum. He makes an interesting comment about the difference between mirrorless and using an optical viewfinder that many may agree with.
There's no hard sell.
It's as if Ricoh are saying, "Go ahead, use an EVF, but if you want to experience something purer and more intimate, then come over to us - we've got something you may like..."
