Sensor K7 and K20D

Can anyone tell me if the K7 sensor is the same as the K20D. It's the same manufacturer? They also have high iso equal in performance.
thank you very much

Both are Samsung CMOS sensors.

There are differences, however, the main one being that the K7 had a 4 channel readout versus a 2 channel readout for the K20. This was to increase the speed of the camera.

The K20 was somewhat better in high ISO performance, IMO, but sample variation in either camera might well result in a K20 and K7 having equal high ISO performance.

Neither holds a candle to the K5 in terms of DR and high ISO performance, however.

They are both Samsung sensors and will more or less behave the same way. As said above some people say the K-7 sensor is a bit worse in high iso. I don't really find it true but I find that the K20D sensor has some awful purple banding at those same high iso...
K-7 sensor enables the video, not the K20 one.

Hello people. The question came to mind that I was looking to buy a second body. Here in Buenos Aires this sale a k20 D at about us$ 500 (everything is more expensive over here) But now that the K5 is being overtaken by new models K5II and K5 IIs, suppose that prices of K5come down . So wait and my second body will be the K7. thanks
