The model Casio Camera (Z200) was released in the year 2008 and is old by digital camera standards.
I assume you live in China as the price shown is very high when compared to other countries.
I looked at sample photos from a Casio Z200 camera.
The left side of the photos are very soft (almost out of focus).
I would not recommend the Casio Z200.

While Casio and Sony both produce very good cameras, one can not judge all of their cameras based on only one camera model.

You did not state what model Sony camera you are considering.
