I have a canon sx-50 hs, it is quite enough without other functions like this device, be objective: leaving the matrix smaller, canon last year announced a device with a 100x superzoom, and the matrix, in my opinion, was much larger, not 1/1, then spending a little more, we will get a good result even shooting with a semi-professional camera.
