Hi, All, Over the years, I have collected many anamorphic projection lenses for my own video projects and experiment. But I have always been puzzled by adapting anamorphic projection lens to my taking lenses, even though I tried every type of adapter that I can buy, but I am still not fully satisfied. So I developed the Rapido Anamorphic Lens Adapter. Please check it out at www.rapidotechnology.com Basically, the adapter offers: a better concentric alignmenta more stable connectiona repeatable alignment: use the marker on the side of the inner ring for quick alignment a reusable and more flexible solution: for different anamorphic lenses, just find the customized step-down ring, and connect to your existing Rapido Anamorphic Adapter, and you are done. No need different, some time hard to find adapter, for each of your anamorphic lensa simple and easy online instruction with illustrations, to show you how to adapt each anamorphic lens at: www.rapidotechnology.comEven though I tried to include all the anamorphic lens that I can find, but I know there are still some are left out, please let me know if you have some anamorphic lens you like to adapt, I typically finish design/manufacturing in 2-3 weeks. Hope you will like it. Thanks, Jim Chang
