Now I just got to figure out how to remove the battery door from my SX130is, I've got the replacement door and hopefully this guide will help me figure out which screws to undo to remove it....
It's not surprising to see other branded products as ODM/OEM (Original Design Manufacturer/Original Equipment Manufacturer) products within things.
Many companies produce parts for other things - if you look at another picture there is an NEC chip in there as well.
I've got a Vauxhall Zafira that has some parts in that designed by Porsche which you wouldn't think.
Also the owner of Sanyo was Mr Matsushita's (Panasonic) relation and some Sanyo parts found their way into Panasonic products (and now Panasonic own Sanyo).
Sony also have worked a lot with Philips for things. The CD laser was a Sony/Philips invention and the TOS link on most devices is also called the S/PDIF socket standing for - Sony/Philips Digital InterFace
So rivals do quite often work with each other in an ODM/OEM setting.
