The Swedish website Monitor has some additional information on the removal of two Samyang lenses by the distributor (XP 50mm f/1.2 and XP 85mm f/1.2) due to design similarity with Zeiss lenses (Google translation):
"This in connection with a conflict between the South Korean manufacturer and the competitor Zeiss, which accuses Samyang of design infringement.
Specifically, the 50 mm and 85 mm lens Samyang Premium XP 50 mm F / 1.2 and Samyang Premium XP 85 mm F / 1.2 touches the stop. As a result, Samyang's lens has begun to be called back by the manufacturer from distributors and retailers all over the world, including the Swedish Zeiss and Samyang distributor Focus Nordic."
