Remarkable improvement The unpleasant sound crackles have been removed (compared to the first 3MP version), the image is a little sharper, and the zoom is a little more precise, but I think you can do even better after an update software. I am satisfied with this purchase. In overcast weather the small integrated solar panel remains insufficient! so it would be necessary to enlarge it by a few centimeters or make it foldable for example for a larger format.
