Which term describes the component that contains the lens, filter, diaphragm, nodal points, and shutter?

• A. Lens Cone Assembly
• B. Shutter
• C. Magazine
• D. Camera Body

Answer: (A)

This term refers to the modular unit that houses the lens and the exposure-control parts as a single assembly. The lens cone assembly contains the optical elements (the lens), any filters, the diaphragm (aperture), the nodal points, and the shutter itself, all integrated together. The camera body is just the outer housing, while the magazine holds film or plates, and the shutter alone is only the exposure mechanism without the optical components. So the lens cone assembly best matches the description of a component that contains all those elements in one unit.
