Lens is functioning to control how the light is focused on the sensor. Converging lens and diverging lens form the lens..Most of the digital camera use 2.0 until 2.8 focus lens.

who is the best presenter???who is the worse presenter??

For me, the best presenter among them is J.Doug Jeffrys. He has all the presenter should have. I learn lot things from him. Using the simple content, he can elaborate the content very well. He was doing the joke to attract attention people to hear his talk. Eye contact with audience will increase the people attention to you. Without shy and nervous, he is the good in controlling the stage. He also has two way communications. So, that their talk become more attractive than others presenter. He also shows a good body language while he talking. The most important things that I respect with him are he gives talk with knowledge and joking, and he also gives example and tips while talking to others people.
About the worse presenter, Microsoft is the worse presenter among them. He loses the attention to the audience because he just talks like talking alone. Not only that, he do not have eyes contact and just look down. Its show that he is shy, nervous and not ready for the talk. He also just static at the podium without controlling the stage very well. Its make audience bored and sleeps will him talking.
