I solved the problem by getting one of each, a D5100 and a D7000. After having used them for a little while, if I had to suddenly have just one of them, it would be the D7000, hands down, easily, no contest at all. As it is, the D7000 is my main camera and the D5100, in theory, is the back-up. I do use both of the cameras. When the macro lens is brought out, it always goes on the D5100. At age 70, lying on the ground while trying to photograph a bug is neither convenient nor comfortable. Therefore, the articulating LCD panel on the D5100 is worth its weight in gold. When attempting to photograph birds in flight, the D7000 is always the one in use due to its superior auto focus functions.
