I used very few shapes, 4 in total:
- Box to make main camera body + the part that has been sub-patched
- Disc for the optic device, I beveled it to make more details + the column on the left side
- Balls for the flash button + glass lens
- Gear for the mode switch
I just wanted it to somehow look like a camera, I didn't try to merge shapes hence so many polygons.
