But that was simply referring to life in general, now you limit that statement to “ So, light bending inside your camera is something you will never see.”, of course this again is false. What effect is there on light when it goes from one medium to another? Say, air to a piece of glass, or two pieces of glass with different refractory properties? The kind of stuff you’d find inside a lens..... It bends.
If "camera" is used here to refer to "camera body" then it is technically correct (except if the rear of the lens has protruded back into the cavity.) Otherwise, yes, you're right. Light bends, and different colours bend by different amounts. Hence rainbows.
