Answers: D5000 vs. Nikon D90:
- Equivalent image quality, altho D5000 tend to underexpose capturing all detail vs. D90 proclivity to overexpose high contrast shots
- D5000 LiveView mode adds subject tracking
- Easy to use auto / scene presets along next to context sensitive help
- More sophisticated interval shooting and time-lapse mode
- Additional in-camera editing including perspective control and fisheye
- Significantly more compact, lighter body
- No autofocus motor in body for elder or more professional lenses
- No top LCD; must use back display to review settings
- No depth of field preview
- Lower resolution peak than D90 but vari-angle allows you to compose hard-to-reach shots
- Slightly slower continuous shot performance (4fps vs 4.5)
- Up to 63 JPEG/11 RAW images can be capture in continuous burst mode (the D90 burst is limited to 25 JPEG/7 RAW images)
- Quiet shooting mode reduce shutter noise in peace situations
- .78x Pentamirror viewfinder vs. the D90's brighter .94x Pentaprism
- Single command dial means more access to Menu for changing settings
- Built-in flash cannot command external flash unit with Nikon Creative Lighting System
- No option for extra mobile grip
- Kit lens only 18-55VR vs 18-105VR
- D5000 adds Airflow Control System within addition to dust reduction system
- Better advantage, especially body only Source(s): http://www.amazon.com/Nikon-D5000-18-55m…
A consumer ("amateur") camera usually has different scene modes as part of its design, usually a smaller vs. full-frame design & just moderate megapixel and processor sizes. They can be pretty fully featured, yet affordable.

A professional camera regularly won't have the scene modes, just guide mode, will be full frame, and have a lot of megapixels & larger processor. They'll habitually also handle more frames per second and not have goofy things similar to incorporating HD video. Additionally, they're often made of more solid construction. These camera bodies (before you add within the lenses) can run $2.5K and up.

The NIkon D90 is a quite high-end consumer camera and may be intimidating to a true beginner near DSLRs. The D40, D60 and D5000 might be better starter cameras.
The difference between a professional and an amateur camera is often more than you'd ponder. A professional camera is one that's designed to be robust, quick (not necessarily easy) to use, flexible, and high characteristic.

Robust: The camera shells are make use of metal components, ports and sockets are sealed against the weather.

Quick to use: Time is spent on the placement of features so the user have quick access to the functions they use everyday, rather than the headline gimmicks.

Flexible: Greater connectivity, allowing the camera to be hooked up to other equipment.

Quality: More than just high pixel counts, it's about physically larger high speed sensors, brighter viewfinders, number of uses up to that time failure, and ease of component repair and replacement.

As for the D90 and the D5000:
The D90 fit's into the Amateur/Prosumer category while the D5000 is manifestly an amateur DSLR. Nikon's current full pro model is the D3X.
