Hi guys,   After some advice. Just bought my first LOMO anamorphic lens. A 50mm f/2.5 OCT-18 square front. I'm hoping to separate the anamorphic part from the prime. I have a 5D so the plan is to attach the anamorphic part to my cannon lenses (e.g. 50mm f1.8) and/or Zenit lenses (50mm, 85mm, 135mm). I know Andrew has done this with cannon FD lenses but I'm not sure what he used to connect the two. Is there a specific lens clamp/ adaptor anyone can recommend?   Thanks Rob
