It is no doubt that nikon was so desperately eager to improvise the new resolution sensor and video mode from their prevoius release made and put it into a lower priced entry level the new nikon D5100 has a good performance in terms of their picture quality and digh definiton video capabillity it is even less expensive but the problem with this is the video time is limited and expensive for entry level its very suitable with the price also and in terms of reliabillity and its very durable and its battery life is very good.
