The current line up of Nikon cropped sensor DSLR (DX) is based around a 12.3 mpix CMOS sensor coupled with a new 14 bits processor (Expeed in Nikon terminology).
This sensor/processor combination has been implanted first in the D300 released in 2007 alongside the similar technology full frame CMOS sensor camera the D3. It was used as a basis for the expert model D90 (2008) and the entry-amateur model d5000 (2009). The D300s constitute an update of the 2007 model, which include video capture and some other minor improvements.
The D300-based series described above constitute a substantial upgrade compared to its predecessor based on the sensor/processor combination initiated on the D200. Please note that D80 and d3000 are also based on this architecture.
Main differences between D300 and D200
| D200 | D300 | |
 |  | |
| sensor | CCD 10.2 mpix | CMOS 12.3 mpix |
| processor | 12 bits | 14 bits |
| LCD | low res 2.5”/230k | high res 3”/920k |
| AF areas | 11 | 51 |
| max fps | 5 | 7 (8 wt grip) |
| meter | same | same |
| live view | No | Yes |
| sensor cleaning | No | Yes |
| D-lighting | No | Yes |
| max iso | 100-3200 | 100-6400 |
| max usable iso | 800 | 1600 |
| viewfinder | 95x | 94x |
Substantial improvements include
- Better low ISO and dynamic range performance
- Better, bigger and higher res LCD (3”/920k) for D300/300s/90, smaller res but movable LCD for d5000
- Better battery performances (with for most model same type of battery EN-EL 3e for D200/300/300s/90)
- In camera corrections like Dynamic Range optimization (D-lighting) or for lens defect like lateral fringes
- Introduces live view and video capability (except D300)
The three main models currently available with the 12.3 Cmos sensor differ mainly in built and mechanical aspects which affect price and weight, the image quality is largely comparable.
These are the main differences
D300S
Same as D300 plus
- HD Video capture (720p/24fps), stereo input,
- Dual card slot (CF+SD)
- Live view with dedicated button and artificial horizon
D300
Main differences vs D90/D5000
- Bigger viewfinder
- More dedicated buttons
- More sophisticated metering sensor
- Can matrix meter manual lenses
- Heavier and more weather resistant mostly metal body
- High speed operation and frame rate
- Faster and more precise AF (51 points)
D90
Main differences with D300
- Smaller and lighter plastic body – not sealed
- Smaller finder
- But same LCD screen
- Slight advantage in high ISO performance
- Cannot meter with manual (non-chipped) lenses
- Less precise 11 areas AF system
- Retains two control wheels (thumb and index) controls
- Uses SD card
D5000
Main differences with D300/D90
- Lower res LCD movable
- No AF motor in body, AF only AFS lenses
- Just one control wheel
Main differences between D300/D90 and D5000
| D300 | D90 | D5000 | |
| Body |  |  |  |
| finder | 94x/100% | 94x/96% | 78x/95% |
| AF | 51 | 11 | 11 |
| LCD | high res 3”/920k | high res 3”/920k | 2.7”/230k moving |
| Meter | 1005-pixel RGB | 420-pixel RGB | 420-pixel RGB |
| meter Ai/Ais | Y | N | N |
| Weight empty | 840g | 620g | 560g |
| Price | 1200-1500 | 700-900 | 500-700 |
Please note that D200 and D300 share a similar chassis based on F100. D80 and D90 share similar chassis based on F80.
