Which Camera best to shoot to focus video or images?

Focus image

Sony is best bcoz 12.0 megapixel. Its cost is approx 12, 000

I think the pink one.

Canon EOS 5D Mark II 21.1MP

The Hasselblad H4D-60 - only about £26, 000 or $39, 600

I'm using GoPro Hero3 White Edition, it is very easy to use and easy to fit it any where, having simple features GoPro Hero3 White Edition, Wi-Fi Remote + App Compatible, It have 5MP camera, with resonable price $199.99.
