Actually, the rain cover served its purpose. That zooming is very awkward, is close ... but I do not know how to make it better ... except with thin disposable sheaths. But will in the long run probably quite expensive. The clear plastic portion of the sheath is extremely deficient in terms of quality ... When I pulled the cover after a few months again from his pocket, I noticed that the transparent part of the shell has completely deteriorated. One can not look at the camera screen quasi because the shell is no longer transparent, but more like milk glass looks. Defective!
