is there any commercial product using ov7670 camera?

If there is any commercial product using it, then it would be a good reference on keep using it on my project.

I am asking this because there is some issues with the camera. For example taking in account the next points: -Adjusting the lens: Lens doesn't stays fixed on some adjusted position by itself i.e. it is loose. I would need it as a fixed focus camera -Aquiring images (for example with Arduino UNO): It needs to take several images before getting a good one. It means it needs auto-adjustment that takes time and memory space(on SD card).

If there is any commercial product that uses this camera then I just would like to research how they got along this this issues.

Thank you
