"Excellent mid range dSLR w/ oustanding picture quality."4.5 starson by kingjames105
Pros: Variety of different shooting modes, in-camera picture editing, HD video capture, great picture quatity, beautiful 3.0 in LCD, LiveView function allows it to work as a point and shoot, Customizable menus, variety of lenses, and solid build quality
Cons: As with any dSLR it is pretty bulky, but is very comfortable to hold. It is quite heavy, and when you add a lense even heavier.
Summary: Overall this is an amazing camera. I have no major complaints with it at all. The picture quality is incredible, even at a high ISO. It has a moderately fast frame rate of 4.5 fps, which easily handles most of your day to day shooting as well as fast enough for most sports, car races, children, etc. The different shooting modes are easy to use and optimize your camera's settings for specific scenes with great results. Great variety of different files to shoot in, with the ability to shoot in RAW as well as JPEG simultaneaously. The in-camera editing is great and easy to use. All the different buttons and dials are easy to navigate and very straight up in their functions.
Unless you are an avid Nikon dSLR user, I would strongly suggest buying a Magic Latern Guide, or a Digital Field Guide by Wiley. These are excellent for beginning to semi-pro photographers and really let you get a grasp of what your Nikon D90 is capable of. The manual can be a little tough to read and completely understand, which is why I would strongly recommend buying a good guide.
I would highly recommend this camera to anyone froma beginning dSLR user, to an advanced dSLR user. Nikon quality is hard to beat and there are so many options when choosing accessories such as lenses, flashes, remotes, etc. If you are looking for a camera in this price range, it is simple, buy the D90.
