Query: Good product, bad description

The name of this product is decieving. It is not an anamorphic adapter for changing the aspect ratio of a camera. Even the "official" photo is shot in such a way that it looks like the front lens curves more horrizontally than vertically, thus exaggerating the confusion of its purpose. Descriptions all over the internet say that it essentially makes the field of view like that of a 16:9 camera. This is nothing other than a wide angle lense adapter. It seems to be a good one, but that's all it is. The biggest downfall of it is that you cannot put threaded filters on the front of it. Probably a precaution to prevent vingetting but would have been an easily solved issue with a step-up ring.
