Rokinon Cine DS 135mm Lens Hood
Description
Lens hood for Rokinon Cine DS 135mm T/2.2 lens (essentially the same as the popular Samyang 135mm lens). Mine came with a petal-style lens hood which seems suboptimal for astrophotography use since I can't guarantee that the imaging chip will be aligned with the petals. So, I finally took the time to learn OpenSCAD and coded it up. Unsurprisingly, it took lots of iteration and online research into approaches [others have taken](https://stargazerslounge.com/topic/307140-3d-printed-nikon-dewlight-shield/) for similar needs, but I finally got it! It includes baffling to minimize light reflections. The OpenSCAD file can be found [here](https://github.com/smitchelus/3D-Models/tree/main/rokinon_135mm_lens_hood) in case you want to tweak the design.
