This was an ambitious project, this model is rigged and has blend shapes for pressing buttons and opening compartments. The film compartment and battery compartment are all part of the same model.
Building the model to this level of detail, inside and out, was maybe to the detriment of the overall look of the piece. I only spent about an hour modelling the outside of the camera but trying to fit in the internals and keeping it all accurate was fairly difficult.
I also attempted to recreate all the textures and text on the camera within blender and it's included tools, I did not use any photo textures in this project. again this model is built more for animation given that it 'works' and is 'rigged'.
it has controls for the sliders and buttons, the compartment doors, the lens cap and the shutter.
