octoplex Posted September 23, 2023 Share Posted September 23, 2023 I want to build a variable-diopter to sit in front of a vintage anamorphic cinema lens. The best off-the-shelf solution is no longer manufactured. It was the Rectilux Hardcore DNA. Does anyone know approximately what lens components are in this thing? My plan is to salvage similar lens elements from other high-quality, second-hand-lenses and then machine my own helicoid etc for focusing. The problem is, I'm not sure what lens components I'm looking for precisely. Is there anyone here who can answer a few basic questions I have about the variable-diopter optics in this type of hardware? It would be greatly appreciated.

octoplex Posted September 23, 2023 Author Share Posted September 23, 2023 UPDATE: I found this video showing how the Rectilux is physically put together, but what I'm struggling to understand is what the lens elements inside it are, and how would I go about salvaging closest-match lens components from (for example) wide-angle adapters etc — the larger, old Century Optics wide-angle adapters have been suggested to me as one potential donor source. Can anyone shed any light on this? Quote Link to comment Share on other sites More sharing options...
kye Posted September 23, 2023 Share Posted September 23, 2023 Maybe @Tito Ferradans might be able to elaborate? octoplex 1 Quote Link to comment Share on other sites More sharing options...
