Don't confuse business agenda and customer needs. These big business employ entire teams of engineering, they need to keep those teams alive because it takes time to build teams with product specific know-how, it take time to build a team, so once they have the lens design team running, they keep making and advertising new lenses even if no one asked for it. And it's the same at Apple, and all other phone makers, they keep making new models to keep their business rolling, even if no one need the new products, they find ways to make people buy new things they don't need. A lot of electronic businesses survival is based on rapid obsolescence and disposal of products that are still working fine.
