Sporting a side-mounted hinged LCD screen, the new 16.2 MP Nikon D5100 sits squarely between the entry level D3100 and the more expensive D7000. Key features of the D5100 include:
- 16.2 megapixel DX-format CMOS sensor
- Side-articulated 3.0″ LCD monitor (920,000 dots)
- 11 AF points (with 3D tracking)
- IS0 100-6400 range (Up to 25,600 equivalent when expanded)
- HD movies (1080p, 720p or WVGA)
- 4 fps continuous shooting
- In-camera effects filters in both stills and video modes
Compared to the D5000, the D5100 expands available ISO two full stops from ISO 6400 to ISO 25,600, ups sensor resolution from 12MP to 16.2MP, has a larger jpeg and RAW shooting buffer, full 1080p HD video, and has a greatly improved LCD – improving from 230,000 pixels to 931,000 pixels. Significantly, the D5100 now features a 14 bit image processing engine which should add significant smoothness to its files compared to its predecessor. Not bad for about $800.00.
