My first scene uploaded here. It's schematic single-reflex camera, you can disasembly lens, or "capture a photo"

controls:
"\" to unlock lens mount
hold "enter (return)" to raise mirror and shutter
"right and left cursor" to zoom out, and zoom in lens.

Enjoy, hope you like it. In future i'm going to make it more realistic, add aperture, do "true" shutter.
