I put 2 stars because not use this camera and all its functionality without a textbook worthy of the name! While there has a few lines in English but are clearly insufficient to set up this unit has many possibilities. When writing to the seller, we obtain answers (in English by a Russian!) But are too limited and too short. I think Amazon should prevent its buyers that the manual (in any language) is too short and should encourage the manufacturer has finally a handbook worthy of the name.
