Why are camera lenses so expensive?
Asked by unknown

Compared to the body, certain types of lenses can be extremely hard to make. Quality aside, if you want a 1.4 aperture 300m telephoto lens, that will be extremely expensive to make (the resulting lens will be huge with lots of glass and components, and most likely impossible to build practically).

The lens manufacturer starts with a mixing of chemicals and fusing them in high temperature, making the glass. The glass is fused, coooled, cutted and polished, and you have a lens.
