Киев-19 и МС Гелиос-81Н 2/50 (eng. Kyiv-19 and MC Helios-81H 2/50) Third Soviet F-mount single-lens reflex camera, developed in 1985. And Multi-coated lense, 50mm f/2. Game oriented model. At first I just wanted to practice creating a simple low poly asset, experiment with shading and stuff, but it ended up trying to make a physically correct working optic with a low poly "frame") The last picture shows a view through the viewfinder in V-Ray.
