Who is the lens manufacturer of the samsung and casio digicam?

AFAIK most of digital camera from was-not-camera-brand use 3rd party lens (sort of co-developed).And for higher quality model they partner with good-reputation lens manufacturer.
For example sony partnering with carl zeiss, kodak with schneider something, panasonic with leica,etc. CMIIW though..
Now, I want to know with whom samsung and casio partner with to develop their digicam lens ?
tnx.

ps:sorry for my poor english

Not sure about casio but for Samsung they use a Schneider branded lens on their higher end point and shoots.

Schneider is a well know lens maker (http://www.schneideroptics.com/) but I believe they're mostly known for commercial products versus consumer products.

For their SLR's, they use Pentax mount compatible lenses since it's a pentax based system.
