What SLR lens should I buy to learn news?

News photography and photojournalist are two concepts. As news photography, it is actually important to record news scenes, and the equipment should not be too heavy. 18-200 camera is more suitable with non-full-frame camera, which is a world of mirrors. And this camera is not as bad as some enthusiasts say, and it can cope with most situations. A fixed focus of 24 or 35mm at most is enough.
