I would like to know how difficult it is to build your own camera module. For instance, how difficult would it be to assemble the Raspberry Pi camera module from scratch?
The reason I'm interested in this, is that camera modules for high quality image sensors often come with horrendous price-tags, and I would like to know why.
An anonymous example [to not shit-talk a specific seller :S]:
You can buy a camera modules for a quite good image sensor for 200 bucks + shipping costs online. However, the image sensor cost ~10$ in mass production, and probably ~20$ in smaller bulk orders. If we then factor in the price for some lenses ~35$ and lens holders ~5$, we come to a total component price of 50-60$.
--> So why is the selling price so high? Do I forget important parts? :S
