By the time I am writing this, Nikon just announced Nikon D5100, a new camera designed for amateur photographers. It has plenty improvements over its predecessor Nikon D5000. Here are some improvements:
- 16 MP image resolution vs 12 MP
- 920k swivel LCD screen vs 230k swivel LCD screen
- Full HD 1080p video recording
- ISO 100-6400 (boostable to 102,400)
These are a few good improvement from D5000. Image quality wise, it is indistinquisable with higher-end Nikon D7000 and even better than D300(s). However, to fully maximize the image resolution, you might want higher quality lens instead of kit lens. It also has higher resolution and side swivel LCD screen which is more practical than D5000 LCD screen design.
However, like most Nikon beginner DSLR cameras, Nikon D5100 does not has built-in auto focus motor (only compatible with Nikon AF-S lenses or third party lenses with internal auto focus motor). It also does not have dedicated buttons as higher end Nikon D7000/D90.
Nikon D5100 will be great for beginner and amateurs that want to get high quality images without spending hundreds $ extra for higher-end DSLR cameras.
Available: Late April, Price: $900 (estimate)
