This is a 3D model of the "Samyang 85mm aspherical IF" lens. I took rough measurements on a copy I have. The model is not highly accurate but nonetheless close to reality. Textures are made by myself with Inkscape, MyPaint and Gimp. I'm not entirely satisfied with the "black airspray" texture that I've produced but I think it works well enough.
Great scene! I'm trying it in Blender 2.78 for rendering virtual LEGO models. Thanks.
