Zs15 sensor better than zs20??
Possibly, but the two sensors are really close in performance, and it takes an experienced photographer to tell the images apart. If you are looking to choose between these two cameras, don't let the sensor megapixels discourage you, there are other more important factors for you to consider - GPS vs battery life, and 60fps HD video being just two of them
