Lenses and resolution

Yes, you are correct, the d7000 screen does not articulate like some of the other camera's, like the 5200 and others. The good thing about Nikkor lenses is they can be used on any camera made in the last 25 years, you may lose some functions, but they are usable, the d7000 is an upgrade, in the camera there is another motor, for focusing, that lets you auto-focus with the less expensive, older lenses, that don't have their own motors, on the d3200 these older non-motor lenses won't have the auto-focus control, like the d7000, for the extra money, the d7000 has much more room to grow, it's 39poimt AF system is bested by only the best Nikons costing into the thousands.
