Canon FD to EF adapter

I don’t know who made the optic but I tried it out at the camera street, with a FD 50mm 1.8 lens. The whole picture literally looks like a dream sequence or something, good if that’s what you want. With the number of FD lens out there I wonder why no one ever tried to make one with good quality corrective optic?
